OMG What the Hell is That? Salmonella Bacteria

salmonella bacteria scanning electron micrograph

Produced by the National Institute of Allergy and Infectious Diseases (NIAID), this digitally-colorized scanning electron micrograph (SEM) depicts a number of red-colored Salmonella sp. bacteria, as they were in the process of invading a mustard-colored, ruffled immune cell. Salmonella sp. bacteria are a common cause of foodborne disease.

These bacteria are members of the family Enterobacteriaceae, and the genus Salmonella. They are Gram-negative, rod-shaped bacilli, and approximately 2000 serotypes cause human disease.

Every year, Salmonella bacteria are estimated to cause one million illnesses, known as salmonellosis, in the United States, with 19,000 hospitalizations and 380 deaths . Most persons infected with Salmonella develop diarrhea, fever, and abdominal cramps 12 to 72 hours after infection.

Salmonellosis, usually lasts four to seven days. Although, most persons recover without treatment, in some persons, the diarrhea may be so severe that the patient needs to be hospitalized.

#OMG What the Hell is That? Yersinia Pestis #Bacteria – #BubonicPlague #wthit #scary

yersinia pestis bacteria bubonic plague

Produced by the National Institute of Allergy and Infectious Diseases (NIAID), this digitally-colorized scanning electron micrograph (SEM) depicts a number of purple-colored Yersinia pestis bacteria that had gathered on the proventricular spines of a Xenopsylla cheopis flea. These spines line the interior of the proventriculus, a part of the flea’s digestive system. The Y. pestis bacterium is the pathogen that causes bubonic plague.

Plague is a disease that affects humans and other mammals. It is caused by the bacterium, Yersinia pestis. Humans usually get plague after being bitten by a rodent flea that is carrying the plague bacterium, or by handling an animal infected with plague. Plague is infamous for killing millions of people in Europe during the Middle Ages. Today, modern antibiotics are effective in treating plague. Without prompt treatment, the disease can cause serious illness or death. Presently, human plague infections continue to occur in the western United States, but significantly more cases occur in parts of Africa and Asia.

OMG What the Hell is That? Staphylococcus Epidermidis Bacteria

staph bacteria micrograph green purple blue

Produced by the National Institute of Allergy and Infectious Diseases (NIAID), this digitally-colorized scanning electron micrograph (SEM) depicts a clump of green-colored, spheroid-shaped Staphylococcus epidermidis bacteria that were enmeshed in a purple-colored, filamentous extracellular matrix, which normally binds cells together within the body’s various tissue types.

Staphylococcus epidermidis are Gram-positive, commensal bacteria normally found as inhabitant of human skin and mucosal surfaces. Infections in human beings have been linked to procedures involving the installation of indwelling medical devices including catheters and implants. With increasing use of biomaterials in the clinical setting, S. epidermidis is becoming more and more prevalent as a nosocomial pathogen.

OMG What the hell is that? Staphylococcus Aureus Bacteria

Produced by the National Institute of Allergy and Infectious Diseases (NIAID), this digitally-colorized scanning electron micrograph (SEM) depicts a clump of yellow-colored, spheroid-shaped Staphylococcus aureus bacteria that were enmeshed in a blue-colored, filamentous extracellular matrix, which normally binds cells together within the body’s various tissue types.

One form of Staphylococcus aureus bacteria known as methicillin-resistant Staphylococcus aureus, or MRSA, causes a range of illnesses, from skin and wound infections to pneumonia and bloodstream infections that can cause sepsis and death. Staph bacteria, including MRSA, are one of the most common causes of healthcare-associated infections.

Resistance to methicillin and related antibiotics (e.g., nafcillin, oxacillin) and resistance to cephalosporins are of concern. CDC estimates 80,461 invasive MRSA infections and 11,285 related deaths occurred in 2011. An unknown but much higher number of less severe infections occurred in both the community and in healthcare settings.

OMG What the hell is that? Staphylococcus aureus (MRSA) bacteria

Produced by the National Institute of Allergy and Infectious Diseases (NIAID), this digitally-colorized scanning electron micrograph (SEM) depicts four magenta-colored, spherical methicillin-resistant Staphylococcus aureus (MRSA) bacteria that were in the process of being phagocytized by a blue-colored human white blood cells (WBCs) known specifically as a neutrophil.

Produced by the National Institute of Allergy and Infectious Diseases (NIAID), this digitally-colorized scanning electron micrograph (SEM) depicts a grouping of red-colored, rod-shaped Mycobacterium tuberculosis bacteria, which cause tuberculosis (TB) in human beings.

The bacteria Mycobacterium tuberculosis usually attack the lungs, but TB bacteria can attack any part of the body such as the kidney, spine, and brain. If not treated properly, TB disease can be fatal. TB disease was once the leading cause of death in the United States.

Produced by the National Institute of Allergy and Infectious Diseases (NIAID), this digitally-colorized scanning electron micrograph (SEM) depicts a single dead yeast particle being phagocytized by a macrophage, which had been activated by the zymosan contained as a component of the yeast particle’s cell wall.

Zymosan found on the surface of fungi, like yeast, is used in microbiologic settings to induce an inflammatory reaction under experimental conditions.

OMG What the Hell is That? HIV Particles

#OMG #WTHIT microbiology-HIV Particles

 

Produced by the National Institute of Allergy and Infectious Diseases (NIAID), this digitally-colorized scanning electron micrograph (SEM) depicts a single, red-colored H9-T cell that had been infected by numerous, spheroid-shaped, mustard-colored human immunodeficiency virus (HIV) particles, which can be seen sttached to the cell’s surface membrane.

HIV is the virus that can lead to acquired immunodeficiency syndrome, or AIDS. Unlike some other viruses, the human body cannot get rid of HIV. That means that once you have HIV, you have it for life.

HIV is a virus spread through body fluids that affects specific cells of the immune system, called CD4 cells, or T cells. Over time, HIV can destroy so many of these cells that the body can’t fight off infections and disease. When this happens, HIV infection leads to AIDS. Learn more about the stages of HIV and how to tell whether you’re infected.
