At a very high magnification of 25,920X, twice that of PHIL 10570 and 10571, this scanning electron micrograph (SEM) revealed some of the morphologic details displayed by a two joined Gram-negative Escherichia coli bacteria. These bacteria were members of the strain, 0:169 H41 ETEC (Enterotoxigenic E. coli).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

See PHIL 11379 for a colorized version of this image.What is ETEC?Escherichia colii is a bacterium that normally lives in the intestines of humans and other animals. Most types of E. coli are harmless, but some can cause disease. Disease-causing E. coli are grouped according to the different ways by which they cause illness. Enterotoxigenic Escherichia coli, or ETEC, is the name given to a group of E. coli that produce special toxins which stimulate the lining of the intestines causing them to secrete excessive fluid, thus producing diarrhea. The toxins and the diseases that ETEC causes are not related to E. coli O157:H7.Created: 2008

Under a magnification of 7075x, this scanning electron micrograph (SEM) depicted a number of Gram-negative Escherichia coli bacteria of the strain O157:H7, which 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.
