This image depicts a Petri dish containing a chocolate agar medium, which had been inoculated with Gram-negative Francisella tularensis live vaccine strain (LVS) bacteria. F. tularensis is the pathogen responsible for causing the disease tularemia. This was the appearance of the colonial growth after 72 hours of incubation. What is tularemia?Tularemia, also known as rabbit fever, is a disease caused by the bacterium Francisella tularensis. Tularemia is typically found in animals, especially rodents, rabbits, and hares. Tularemia is usually a rural disease and has been reported in all U.S. states except Hawaii.How do people become infected with tularemia?Typically, people become infected through the bite of infected insects (most commonly, ticks and deerflies), by handling infected sick or dead animals, by eating or drinking contaminated food or water, or by inhaling airborne bacteria.Created: 2009

Using methylene blue stain, this photomicrograph revealed the presence of Francisella tularensis bacteria, formerly known as Pasteurella tularensis. F. tularensis is the pathogen responsible for causing the disease tularemia.What is Tularemia?Tularemia is a potentially serious illness that occurs naturally in the United States. It is caused by the bacterium Francisella tularensis found in animals (especially rodents, rabbits, and hares).What are the Symptoms of Tularemia?Symptoms of tularemia could include: - sudden fever- chills - headaches- diarrhea - muscle - aches - joint pain - dry cough - progressive weaknessPeople can also catch pneumonia and develop chest pain, bloody sputum and can have trouble breathing and even sometimes stop breathing.Created: 1972

This photomicrograph of a Gimenez-stained yolk sac smear revealed the presence of Rickettsia rickettsii bacteria, which are the cause of Rocky Mountain spotted fever (RMSF). These bacteria range in size from 0.2 x 0.5 micrometers to 0.3 x 2.0 micrometers. They are difficult to see in tissues by using routine histologic stains, and generally require the use of special staining methods, such as the Gimenez stain used in this case.Created: 1974

At an extremely high magnification of 44, 818X, twice that of PHIL 10574 and 10575, this colorized scanning electron micrograph (SEM) revealed some of the morphologic details displayed by a single Gram-negative Escherichia coli bacterium. This bacterium was a member of the strain, 0:169 H41 ETEC (Enterotoxigenic E. coli). See PHIL 10576 for a black and white version of this image.Enterotoxigenic E. coli, a common cause of bacterial diarrhea
Enterotoxigenic Escherichia coli, or ETEC, is an important cause of bacterial diarrheal illness. Infection with ETEC is the leading cause of travelers' diarrhea and a major cause of diarrheal disease in underdeveloped nations, especially among children. ETEC is transmitted by food or water contaminated with animal or human feces. Although ETEC causes a significant amount of illness worldwide, the infection will end on its own and is rarely life-threatening.Created: 2008

Under a high magnification of 10961x, this colorized scanning electron micrograph (SEM) depicted a number of Gram-negative Escherichia coli bacteria of the strain O157:H7. E. coli O157:H7 is one of hundreds of strains of this bacterium. Although most strains are harmless, and live in the intestines of healthy humans and animals, this strain produces a powerful toxin, which can cause severe illness.E. coli O157:H7 was first recognized as a cause of illness in 1982 during an outbreak of severe bloody diarrhea; the outbreak was traced to contaminated hamburgers. Since then, most infections have come from eating undercooked ground beef.The combination of letters and numbers in the name of the bacterium refers to the specific markers found on its surface, which distinguishes it from other types of E. coli.
