This digitally colorized scanning electron microscopic (SEM) image revealed some of the comparative ultrastructure between normal red blood cells (RBCs), and a sickle cell RBC (left) found in a blood specimen of an 18-year-old female patient with sickle cell anemia (HbSS). People who have this form of sickle cell disease, inherit two sickle cell genes (S), one from each parent. HbSS is usually the most severe form of the disease. Sickle cell disease encompasses a group of inherited RBC disorders. Healthy RBCs are round, and move smoothly through blood vessels. In sickle cell disease, the RBCs become hard, and sticky, and look like a C-shaped farm tool called a sickle. The sickle cells die early, which causes a constant shortage of RBCs. Also, when they travel through small blood vessels, they get stuck and clog the blood flow. This can cause pain and other serious problems.

Dr. Goldberger began fighting tropical fevers, typhus, typhoid, and other infectious outbreaks throughout the United States and the Caribbean. Due his many successes, he was later assigned the task of tackling pellagra, a disease which causes skin rashes, mouth sores, diarrhea and if untreated, mental deterioration. His observations in southern mental hospitals, orphanages, and mill towns led him to believe the problem was not infectious, but nutritional. This theory contradicted commonly held medical opinions, but Goldberger fought to convince critics that social reform was necessary to improve diets of Southern tenant farmers and mill workers. Even though Dr. Goldberger died before finding its exact cause, which was later discovered to be a diet deficient in niacin, his selfless devotion to public health was an example to many.

To inform selection of the vaccine viruses used in the seasonal influenza vaccine, Centers for Disease Control and Prevention (CDC) scientists use a test called the hemagglutinin inhibition (HI) assay to characterize influenza viruses according to the "antigens" on the virus' surface. Antigens are molecular structures on the surface of viruses that are recognized by the immune system, and are capable of triggering an immune response, and antibody production. Antigens play a key role in the influenza virus' ability to bind to, and enter cells in the nose, throat and lungs. The HI test measures how well antibodies made from an immune response against a specific influenza virus, bind to other influenza viruses, and thus inactivate them. Scientists also use the HI test to compare antigenic changes in currently circulating influenza viruses, to influenza viruses that have circulated in the past. Here, an HI machine is preparing to perform the HI test.

These blooms most commonly occur in fresh water, such as lakes, ponds, rivers, and streams. They can look like foam, scum, mats, or paint on the surface of the water, and can make the water appear different colors, including green, blue, red, or brown.

This photograph depicts a young Ghanaian woman holding a pipe filter that she wore draped on a cord about her neck. Pipe filters are individual filtration devices, similar to a straw, which allow people to filter their water to avoid contracting Guinea worm disease (GWD), while traveling, or working in the field. Persons become infected by drinking water containing copepods, or water fleas that harbor the infective stage Dracunculus medinensis larvae. Once inside the body, the stomach acid digests the water flea, but not the larvae, which find their way to the small intestine, where they penetrate the wall of the intestine and pass into the body cavity. During the next 10 to14-months, the Guinea worms mature to a full-size adult 2 to 3-feet long, and as wide as a cooked spaghetti noodle. Adult worms mate inside the abdomen. After which, the male dies and the female worm migrates to the site where she will emerge, usually from lower limbs.

Following influenza infection, or receipt of the influenza vaccine, the body's immune system develops antibodies that recognize, and bind to what are known as the virion's antigenic sites, composed of the influenza virus' surface proteins. By binding to these antigenic sites, antibodies neutralize flu viruses, which prevents them from causing further infection.

Photographed from the left rear, this photograph revealed the March of Dimes insignia placed on this Emerson respirator, also known as an iron lung, which was used by polio patients whose ability to breath was paralyzed due to this crippling viral disease. This particular iron lung was donated to the Centers for Disease Control and Prevention's (CDC), David J. Sencer Museum, by the family of polio patient Mr. Barton Hebert of Covington, Louisiana. Mr. Hebert used the device from the late 1950s, until his death in 2003. Iron lungs encase the thoracic cavity externally in an airtight chamber. The chamber is used to create a negative pressure around the thoracic cavity, thereby, causing air to rush into the lungs, thereby, equalizing intrapulmonary pressure with that exterior to the body. By 1970, J. H. Emerson Co. ceased manufacturing this apparatus, but many still depend on such mechanical ventilation systems on a daily basis.

Photographed from the right front, this photograph depicts an opened Emerson respirator, also known as an iron lung, which was used by polio patients whose ability to breath was paralyzed due to this crippling viral disease. This interior view enables you to see the mattress, upon which a polio patient would lay when enclosed. This particular iron lung was donated to the Centers for Disease Control and Prevention's (CDC), David J. Sencer Museum, by the family of polio patient Mr. Barton Hebert of Covington, Louisiana. Mr. Hebert used the device from the late 1950s, until his death in 2003. Iron lungs encase the thoracic cavity externally in an airtight chamber. The chamber is used to create a negative pressure around the thoracic cavity, thereby, causing air to rush into the lungs, thereby, equalizing intrapulmonary pressure with that exterior to the body.

This image depicts the subcutaneous emergence of a female Guinea worm, Dracunculus medinensis, from the sole of a patient's right foot with Guinea worm disease (GWD). Before the worm emerges, a blister develops on the skin. This blister causes a very painful burning sensation, rupturing within 24-72 hours, leaving an ulcerative lesion. At the bottom of the ulcer, is the anterior end of the Guinea worm. For relief, persons will immerse the affected limb into water. When a person with a Guinea worm ulcer enters the water, the adult female worm releases a milky white liquid containing millions of immature larvae into the water, thereby, contaminating the water supply. For several days after its emergence from the ulcer, the female Guinea worm is capable of releasing more larvae whenever it comes into contact with water. Note the purulent subcutaneous infection surrounding the rupture site.

This was a photographic portrait of Dr. Alexander D. Langmuir, chief epidemiologist at the Centers for Disease Control and Prevention (CDC) for two decades. Dr. Langmuir founded the Disease Investigations Branch of the Epidemic Intelligence Service (EIS) in 1951. He was a strong proponent of shoe leather epidemiology--an intense focus on the people and places where the disease outbreaks actually occurred, and the precise gathering of statistics to support whatever action was needed. In starting the CDC EIS program, his goal was to introduce professionals from medicine, and relevant social sciences, to the science of epidemiology, hoping that they would become well educated in the practice of public health. As a result, many of these disease detectives continued on in the field of epidemiology, while others carried that knowledge with them into whatever careers they chose, as advocates for sound public health practice.

The photo shows a Culiseta melanura mosquito preparing to feed on a blue jay. Eastern equine encephalitis virus (EEEV) is maintained in a cycle between Cs. melanura mosquitoes, and avian hosts, in freshwater hardwood swamps. Cs. melanura is not considered to be an important vector of EEEV to people, because it feeds almost exclusively on birds. Transmission to people requires another mosquito species to create a "bridge" between infected birds, and uninfected mammals, such as people, or horses. Most of the bridge species are within the Aedes, Coquillettidia, and Culex genera.

Under a magnification of 1000X, this photomicrograph revealed the presence of a deformed red blood cell (RBC), or erythrocyte (arrowhead), which had taken on a flattened, sickle-shaped appearance, unlike the rounded, biconcave appearance assumed by the surrounding normal RBCs. This RBC morphology was indicative of sickle cell disease (SCD), a genetic condition that is present at birth. It is inherited when a child receives two sickle cell genes, one from each parent. Healthy red blood cells are round, and they easily move through small blood vessels, while sickle cells are sticky, and have a difficult time freely moving through the vessels. The sickle cells die early, which causes a constant shortage of red blood cells. Vessel obstruction can cause pain and other serious problems including infection, acute chest syndrome, and stroke.

Under a magnification of 400X, this photomicrograph revealed some of the ultrastructural morphology displayed by a species of the filamentous fungus of the genus, Gliocladium. Apparent here, were the thin-walled, transparent, or hyaline conidiophores, which were branched. At their distal tip you can see the flask-shaped phialides, and it's atop these phialides, taking the shape of an oval cluster, that the single-celled conidia emerge. This entire morphologic structure, i.e., conidiophores, phialides, and conidia, is referred to as a penicillus, from Latin for tuft of hair. Members of the genus Gliocladium morphologically resemble those of the genus Penicillium, however, as was the case here in this Gliocladium species, you'll note that the conidia clump together in the shape of a single, ball-shaped mass, while Penicillium genus members display chains of conidia.

As described by Ms. Burkel, "This photo depicts the love and labor involved in collecting data in the field, as National Institute for Occupational Safety and Health (NIOSH), Biological Lab Technician, John Clark, demonstrates the methodology, and force involved in performing a spirometry test, which he demonstrated for each study subject. A spirometer measures lung volume and function, when a study participant expires as much air as possible. This is an important reflection of lung health, especially because NIOSH is interested to know if carbon nanotube, or nanofiber exposure at the workplace, is associated with lung function."

This 2004 photograph depicts a Nigerian man inside a Guinea worm containment center, wearing a pipe filter around his neck, through which he can drink pond water without risk of Guinea worm, Dracunculus medinensis, infection. Often, young men, usually farmers and cattle herders, find themselves at greater risk for disease because they are away for weeks from the community base where household filtered water should be available. Instead, they drink from numerous unprotected water sources, while working in the field. The pipe filter acts as a portable straw that can filter the copepods, or water fleas, that carry the parasitic larvae of the Guinea worm. Case containment centers not only provide free treatment to Guinea worm disease (GWD) patients, who voluntarily come for therapy, but educate the sufferers as to how to avoid the infection.

This digitally colorized scanning electron microscopic (SEM) image depicted eight Gram-negative, Sebaldella termitidis bacteria. "The genome of ATCC 33386, S. termitidis, was recently sequenced, as part of the U.S. Department of Energy - Joint Genome Institute's (DOE-JGI) Genomic Encyclopedia of Bacteria and Archaea (GEBA) project. The GEBA project is aimed at systematically filling in the gaps in sequencing along the bacterial and archaeal branches of the tree of life. Though the wide variety of microbial sequencing projects undertaken throughout the world has created a rich, diverse collection of microbial genomes, strong biases in what has been sequenced thus far are evident. This project represents the first systematic attempt to use the tree of life itself as a guide to sequencing target selection."

Photographed from the front, this photograph depicts an Emerson respirator, also known as an iron lung, which was used by polio patients whose ability to breath was paralyzed due to this crippling viral disease. This particular iron lung was donated to the Centers for Disease Control and Prevention's (CDC), David J. Sencer Museum, by the family of polio patient Mr. Barton Hebert of Covington, Louisiana, Mr. Covington used the device from the late 1950s, until his death in 2003. Iron lungs encase the thoracic cavity externally in an airtight chamber. The chamber is used to create a negative pressure around the thoracic cavity, thereby, causing air to rush into the lungs, thereby, equalizing intrapulmonary pressure with that exterior to the body. By 1970, J. H. Emerson Co. ceased manufacturing this apparatus, but many still depend on such mechanical ventilation systems on a daily basis.

Magnified 1000X, this scanning electron microscopic (SEM) image revealed some of the minute exoskeletal details found at the proboscis tip of an unidentified mosquito found deceased in the suburbs of Decatur, Georgia. The proboscis is the organ used by this, as well as other like insects, to feed upon the blood of a warm-blooded host, including human beings. What you see here, is the sheath that encases a pair of needle-sharp stylets, which together are known as the fascicle. The larger of the two stylets, known as the labrum, when viewed in cross-section, takes on the shape of a V, and acts as a gutter, which directs the ingested host blood towards the insect's mouth. The hair-like structures are known as setae, and are really extensions of the insect's exoskeletal, chitinous covering. These setae act as sensory organs, transmitting impulses indicating changes in the organism's environment.

This 1966 image depicts a clinic annex building in what was formerly the country of East Pakistan, and in 1971, was renamed Bangladesh. The signage on the side of the annex, indicated the World Health Organization's (WHO) goal of eradicating smallpox. The annex building was located next to the WHO smallpox eradication program headquarters, which was located in what was previously Dacca, but is now Dhaka, and across a field from the old Cholera Hospital, and its associated research laboratories. The laboratories became what are now the Bangladesh International Center for Diarrheal Disease Research. The annex housed the radio shack for communicating with WHO staff around the country, and also contained two meeting rooms. In 1980 the WHO declared the global eradication of smallpox due to a worldwide vaccination campaign. The WHO then recommended that all countries cease vaccination.

This 1970 photograph was created during an investigation that took place in Alamogordo, New Mexico, in Otero County, dealing with a number of cases involving human and porcine, methylmercury poisoning. Inside a hog pen, this public health investigator was conducting an examination upon hogs suspected of having consumed feed that had been contaminated with methylmercury. It was determined that a hog, fed grains treated with methylmercury dicyanamide (a fungicide), was later butchered, and its meat was fed to the hog owner's family members, who in turn began to exhibit symptoms indicative of mercury poisoning, which included "ataxia, decreased vision, and depression of consciousness, which progressed to coma over a period of 3-weeks". Subsequent studies on urine specimens from the affected family members, the pork, and the grain seed, all showed results indicative of abnormally high levels of mercury, confirming the diagnosis of organic mercury poisoning.

This photograph depicts a Nigerian man, who was having a Guinea worm, Dracunculus medinensis, extracted from his right lower leg. The roundworm has emerged from its subcutaneous burrow, just distal to the posterior knee region. The worm has migrated, over a period of approximately one year, to its site of emergence, to release its eggs in a local pond or stream. Before the worm emerges, a blister develops on the skin, causing a very painful burning sensation before rupturing within 24 to 72-hours. Once the white, spaghetti-like worm emerges from the wound, it is pulled out only a few centimeters each day, and wrapped around a small stick or piece of gauze. Sometimes a worm can be pulled out completely within a few days, but this painful process often takes weeks.

This western diamondback rattlesnake, Crotalus atrox, is a well-known, large, gray to rust-colored serpent that is widely distributed across the southwestern, to southcentral aspect of the United States, and adjacent Mexico (Klauber, 1997; Campbell and Lamar, 2004). It's abundant along 80% of the Texas Gulf Coast and its barrier islands, as well as the Tamaulipan region along the southern Rio Grande valley (Tennant 1998), placing it in hurricane-prone areas, which is of importance to those living in these regions, and first-responders. The average adult size varies considerably across its range. In Starr, Willacy, and Hidalgo counties in South Texas, C. atrox commonly grow over 5ft. in length, (Tennant, 1998), and is a highly-excitable, aggressive rattlesnake, responsible for a significant portion of the venomous snake bites, and most of the snakebite fatalities reported in the U. S. each year (Russell, 1980; Gold, 2002).

Magnified 8000X, this digitally colorized scanning electron microscopic (SEM) image revealed some of the ultrastructure displayed by red blood cells (RBCs) from a 6-year-old male patient that has sickle cell with hereditary persistence of fetal hemoglobin (S-HPFH). The persistent fetal hemoglobin reduces the severity of the consequences of the sickle cell disease, thereby, reducing the degree of cellular deformity, or sickling. Sickle cell disease encompasses a group of inherited RBC disorders. Healthy RBCs are round, and move smoothly through blood vessels. In sickle cell disease, the RBCs become hard, and sticky, and look like a C-shaped farm tool called a sickle. Sickle cells die early, which causes a constant shortage of RBCs. Also, when they travel through small blood vessels, they get stuck and clog the blood flow. This can cause pain and other serious problems.

At a magnification of 42X, this 2005 scanning electron microscopic (SEM) image depicts the morphological characteristics seen at the distal end of a domesticated cat, Felis catus, claw. Arranged in a lamellar, or layered configuration, much the same way as an onion, the claw grows from the inside outward. The older, or outermost layers, are sloughed off as the nail ages. This sloughing process produces what are termed claw husks, which are ghost-like remnants reflecting the overall shape of the original nail. The claw is constructed from keratin, a dense, durable protein, which is also the primary constituent of skin and hair. The outer, hard layered portion of the claw is called the unguis, and the inner, softer, underside layer is termed the subunguis.

Caption:This Petri dish culture plate contained an unknown growth medium, to which an inoculum of Staphylococci sp. bacteria had been applied. Atop the growth medium, antibiotic-impregnated disks had been laid, which gave rise to this example of an antibiotic sensitivity test. The medium was kept at a pH of 7.2. The size of the inhibition zones surrounding the antibiotic-impregnated paper disks, depended on the level of sensitivity the bacteria, present in the agar, had to the antibiotic, as well as the antibiotic's ability to diffuse through the culture medium. The overall pH of the medium, in this case 7.2, also played an important role in influencing the results of this antimicrobial sensitivity study.

This image depicts a close view of the skin surface of a patient, who had presented with these two red papular lesions that were determined to be senile angiomas, also known as Campbell de Morgan spots, or cherry angiomas. Note that a pencil eraser had been added to the field of view in order to provide some measure of scale, emphasizing the small size of these angiomas. These lesions are noncancerous, and are composed of numerous capillaries, which proliferate, due to reasons unknown. Usually they appear in middle age, and increase in number as one ages. The coloration of these small capillary clusters is bright red to purple, and are harmless, except for their possible unaesthetic component.

This 1996 image depicted a woman departing a grocery store, while pushing a shopping cart. Due to the nature of the act of pushing the cart, had there have been a door with which to contend, the opening, and subsequent avoidance of its closure, would have made exiting the store more difficult. However, the automatic, electronic eye-controlled door facilitated the exiting of the store, reducing a patron's need to negotiate another portal. Widely used, no-touch automatic doors accommodate all types of users, including the mobility-challenged, as well as those whose hands are filled with purchases. Simple, and in common use, the wide automatic door is an excellent example of Universal Design. Other facilities should, where possible, consider this option.

This was a scene captured from a guided tourist boat, passing along a canal, also known locally as a khlong, in Bangkok, Thailand in 1971. Depicted, was a home that displayed numerous orchid plants on its deck facing the canal. Once an all-important aspect to life in Thailand, these canals are becoming fewer and fewer, sometimes being filled in, and paved over in order to make room for new roadways. Many years ago, before Bangkok became industrialized with the addition of numerous roads and buildings, the canal water was clean enough to drink. However, over time, various community waste products that were pumped, or leeched into the canals, have made the water undrinkable, and unfit for bathing. Recently, the Thai government has begun instituting campaigns that will help to improve awareness of the clean-up measures that will hopefully restore Thai canals to their once pristine nature.

This 3-dimensional (3D) image illustrates the very beginning stages of an influenza (flu) infection. Most experts think that influenza viruses spread mainly through small droplets containing influenza virus. These droplets are expelled into the air when people infected with the flu, cough, sneeze or talk. Once in the air, these small infectious droplets can land in the mouths or noses of people who are nearby. This image shows what happens after these influenza viruses enter the human body. The viruses attach to cells within the nasal passages and throat (i.e., the respiratory tract). The influenza virus’s hemagglutinin (HA) surface proteins then bind to the sialic acid receptors on the surface of a human respiratory tract cell. The structure of the influenza virus’s HA surface proteins is designed to fit the sialic acid receptors of the human cell, like a key to a lock. Once the key enters the lock, the influenza virus is then able to enter and infect the cell. This marks the beginning of a flu infection. See PHIL 15325, for this image with no labels, and PHIL 15326, for a labeled version of this image. The cut-out box shows a close-up view of how an influenza virus’s HA surface protein binds to a sialic acid on the surface of a human respiratory tract cell.

Huddled in their coop, these chickens were being raised for their eggs in a privately-owned pen. Male and female birds, were all grouped together. Eggs from these chickens were collected each morning to be used as food by their owners. It's common for chickens, ducks, and other poultry to carry Salmonella bacteria, which is a type of germ that naturally lives in the intestines of poultry, and many other animals, and is shed in their droppings, or feces. Even organically fed poultry can carry Salmonella organisms. While it usually doesn't make the birds sick, these bacteria can cause serious illness when it is passed to people.

What do you do if you are in the middle of a remote village that has no electricity, or running water, it's raining, and you need a dry place with a little light, in order to set up a lab for the night? You use the backseat of the team's land cruiser, of course. Captured in 2016, in the Quartier Morin commune in Haiti, this photograph, depicted a lab tech, who was in the process of performing a fingerstick on a man in the community, in order to extract a blood sample, to look for the parasite, Wuchereria bancrofti. As the parasite is best detected in the blood at night, lab teams went into the field after 9:30pm, to begin their work. Here, the nurse was standing next to the lab tech with a bag of two different anti-parasitic medications, and a glass of water. Once the blood had been drawn, the nurse would treat the patient on the spot. These activities actually made the team's Land Cruiser a backseat lab, pharmacy, and nurse's station!

This image showed a Latin American woman standing in a pit, which had been dug down to a water pipe through which water was being pumped. This pipe had been intentionally punctured, enabling the water within to leak out into a collection bucket with which this woman, and others like her, would collect, and bring water back to their homes. In Latin America, waterborne transmission continues to play an important role in the spread of diseases like cholera. Large municipal water distribution systems distribute unfiltered, and unchlorinated water through leaky pipes at low pressure. Nearby this pit, were others, where sewage was being collected, to be used by city inhabitants to fertilize and water gardens in small fields between houses. These unsanitary methods enable water in this pipe to become contaminated, when the pipe's interior pressure drops below safe levels, and back siphonage occurs, allowing dirty water to enter the clean water system.

This image depicts a Centers for Disease Control and Prevention (CDC) scientist placing samples into a real-time PCR machine, known as a Corbett Research Rotor-Gene 6000 thermocycler, in order to identify the various types of poliovirus contained therein. The data from this analysis is stored in a computer, while the software further analyzes the data before being reviewed by a scientist. The themocycler can vary the temperature, which is important, for PCR requires multiple test rounds at different temperatures. In the instrument, viral RNA is copied into DNA and then the DNA is amplified. Specific probes bind to the DNA, in order to determine what type of polio present. One hundred ten labs around the world can run this assay, and can tell if an isolate contains polio, or not, and if so, what kind.

This 3-dimensional (3D) image illustrates the very beginning stages of an influenza (flu) infection. Most experts think that influenza viruses spread mainly through small droplets containing influenza virus. These droplets are expelled into the air when people infected with the flu, cough, sneeze or talk. Once in the air, these small infectious droplets can land in the mouths or noses of people who are nearby. This image shows what happens after these influenza viruses enter the human body. The viruses attach to cells within the nasal passages and throat, i.e., the respiratory tract. The influenza virus's hemagglutinin (HA) surface proteins then bind to the sialic acid receptors on the surface of a human respiratory tract cell. The structure of the influenza virus's HA surface proteins is designed to fit the sialic acid receptors of the human cell, like a key to a lock. Once the key enters the lock, the influenza virus is then able to enter and infect the cell. This marks the beginning of a flu infection. The cut-out box shows a close-up view of how an influenza virus's HA surface protein binds to a sialic acid on the surface of a human respiratory tract cell.

This image depicts a Centers for Disease Control and Prevention (CDC) scientist, who was quantitatively measuring the polio antibodies present in someone's blood. Each of these purple colored plates tests four serum samples, for antibodies against a single poliovirus serotype. This scientist was using a robotic plate stacker to collect data from the stained serology plates. This test allows one to determine how many antibodies are present, by using the color purple. A purple well means the antibodies in the serum sample prevented poliovirus from infecting and killing cells within the cell culture. If the well shows up as colorless, this means that antibodies did not block the virus from infecting and killing the cells. The presence of antibodies in a serum sample, capable of blocking poliovirus from infecting cells, means that the person, from whom the sample was extracted, is protected from developing paralysis after exposure to poliovirus.

Photographed from the right front, this photograph depicts an opened Emerson respirator, also known as an iron lung, which was used by polio patients whose ability to breath was paralyzed due to this crippling viral disease. This interior view enables you to see the mattress, upon which a polio patient would lay when enclosed. This particular iron lung was donated to the Centers for Disease Control and Prevention's (CDC), David J. Sencer Museum, by the family of polio patient Mr. Barton Hebert of Covington, Louisiana, Mr. Covington used the device from the late 1950s, until his death in 2003. Iron lungs encase the thoracic cavity externally in an airtight chamber. The chamber is used to create a negative pressure around the thoracic cavity, thereby, causing air to rush into the lungs, thereby, equalizing intrapulmonary pressure with that exterior to the body.

Magnified 8000X, this digitally colorized scanning electron microscopic (SEM) image depicted a large grouping of Legionella pneumophila bacteria. Note the presence of an elongated-rod morphology in some organisms, seen in other images from this series as well. L. pneumophila frequently elongate when grown in broth, when plate-grown cells age, or when refrigerated, as in this case. Usually, L. pneumophila are stout, fat bacilli, which was the morphology displayed by the majority of these organisms. These bacteria originated on a 1 week-old culture plate (+/- 1 day), forming a single colony, at 37oC, on a buffered charcoal yeast extract (BCYE) medium with no antibiotics. The original sample was acid-treated for 15 min, to minimize fungal impurities, which would have inhibited the visualization of these organisms.

This machine is a sequencing instrument, a Sanger sequencer, which implements a traditional type of sequencing. The plates go in and the machine analyzes the reactions. Each base is represented by a different color. The machine processes the bases, and sorts them, producing this four-color chromatogram. The peaks on the graph correspond to the intensity of color, and translates each color into a letter. By reading left to right, one can see the sequence of the material. A computer compares one viral sequence to another, and determines how closely related different viruses are to one another. This creates a family tree of viruses that allows CDC to visualize how the viruses are moving throughout a country. Reservoirs are then identified, from which the virus spreads. Sequencing gives us a window as to where a virus has been, and how long it has been circulating, allowing CDC to focus its vaccination programs on specific regions inside pertinent countries.

This is a composited view, combining three images captured at the water's surface, as this soon-to-be adult Anopheles sp. mosquito was about to begin its life as a winged warrior. Emerging from its pupal exoskeleton, if this was a female mosquito, she would quickly assume her role as a malarial vector, obtaining her blood meal from her mammalian hosts, once every few days, and soon begin laying her own eggs at a rate of 50-200 eggs per oviposition. See PHIL 18764, and 18765, for two of these individual composited stages of this emerging mosquito, helping to tell the story of the next phase of this insect's lifecycle.

This image was captured in 2014, by U.S. Centers for Disease Control and Prevention (CDC) Veterinary Medical Officer, Ryan M. Wallace, DVM, MPH. In some countries, cultural practices prohibit euthanasia of unwanted, diseased, and aggressive animals. For these countries, they must find alternative methods for controlling street dog populations. This Buddhist temple provides a refuge for street dogs. However, the prospects of adoption are near non-existent. When many dogs enter, but no dogs leave, it results in overcrowding, unsanitary conditions, death and disease. Volunteers at this temple do their best to provide care for these dogs, but without alternative methods for population control the result is often not a positive one.

This image depicts the process of hydraulic fracturing, or fracking, a 24/7 activity, and shows how the need for occupational health and safety never stops. NIOSH researchers from the Western States Division, and the Division of Applied Research and Technology, were the first to systematically document hazardous exposures to workers at fracking sites, including exposures to respirable crystalline silica (RCS), diesel particulate matter, and volatile organic compounds. This sand mover operator was monitoring the sand level in the blender tub, framed in the bottom left handrail. His half-face cartridge respirator, may not have been providing a high enough assigned protection factor to protect him from the elevated concentration of RCS, to which he was exposed. This photograph was taken in Encinal, Texas, during a test of a NIOSH-developed engineering control, known as the NIOSH mini-baghouse retrofit assembly, installed to reduce RCS emissions.

To inform selection of the vaccine viruses used in the seasonal influenza vaccine, Centers for Disease Control and Prevention (CDC) scientists use a test called the hemagglutinin inhibition (HI) assay to characterize influenza viruses according to the antigens on the virus' surface. Antigens are molecular structures that are recognized by the immune system, and are capable of triggering an immune response, and antibody production. Antigens play a key role in the influenza virus' ability to bind to, and enter cells in the nose, throat and lungs. The HI test measures how well antibodies made from an immune response against a specific influenza virus bind to other influenza viruses, and thus inactivate them. Scientists also use the HI test to compare antigenic changes in currently circulating influenza viruses with influenza viruses that have circulated in the past. Here, an HI machine is prepared to perform the HI test.

This image depicts a Centers for Disease Control and Prevention (CDC) scientist interacting with her Caliper LifeSciences' Zephyr Molecular Biology Workstation, working with samples to be tested using a real-time PCR machine, known as a themocycler (see PHIL 22904), in order to identify the various types of poliovirus contained therein. The data from this analysis is stored in a computer, while the software further analyzes the data before being reviewed by a scientist. The themocycler can vary the temperature, which is important, for PCR requires multiple test rounds at different temperatures. In the instrument, viral RNA is copied into DNA and then the DNA is amplified. Specific probes bind to the DNA, in order to determine what type of polio present. One hundred ten labs around the world can run this assay, and can tell if an isolate contains polio, or not, and if so, what kind.

Centers for Disease Control and Prevention (CDC) performs genome sequencing to compare the genetic sequences of vaccine viruses with those of circulating viruses. This is one way to assess how closely related the circulating influenza viruses are to the viruses the influenza vaccine is formulated to protect against.CDC uses "Next Generation Sequencing" (NGS) methodologies that provide a tremendous amount of detail about each influenza genome. NGS techniques represent various high-throughput DNA sequencing strategies, whereby, millions to billions of DNA strands are sequenced in a highly parallel manner, dramatically improving throughput to understand sample complexity. This level of detail benefits decision-making with regard to vaccine composition, because it can help identify emerging changes in circulating flu viruses much earlier than before. Here, a scientist prepares a sequencer machine for a run.

In order to test whether the flu virus in a sample taken from a patient matches an influenza vaccine virus, the sample needs to be grown in a cell culture, or an embryonated chicken egg. Growing the virus in cell culture or eggs, produces a larger volume and concentration of virus than what was in the original sample. The larger volume of flu virus is needed for additional laboratory tests. These eggs had been injected with influenza virus, and were warming in an incubator. The warmth encourages influenza viruses to grow faster than they would at room temperature. The eggs will stay in the incubator for two to three days, depending on the influenza viruses they contain. Influenza B viruses take a bit longer to grow with this method compared to influenza A viruses.

In order to test whether the flu virus in a sample taken from a patient matches an influenza vaccine virus, the sample needs to be grown in a cell culture, or an embryonated chicken egg. Growing the virus in cell culture or eggs, produces a larger volume and concentration of virus than what was in the original sample. The larger volume of flu virus is needed for additional laboratory tests. In this case, this Centers for Disease Control and Prevention (CDC) scientist was in the process of using a small needle in order to puncture a hole in the top of each of these embryonated chicken eggs. A syringe will then be inserted into the hole, and inject influenza virus into a specific cavity (a sac) inside the egg. There the influenza virus will grow and multiply.
