The data from this study helped shape another piece of the puzzle by looking at the physiological effects of a single Taser activation in human subjects,â said study director Gary Vilke, M.D., professor of clinical medicine and director of Clinical Research for Emergency Medicine at UC San Diego.
Definition. Escherichia coli (E. coli) bacteria normally live in the intestines of healthy people and animals. Most varieties of E. coli are harmless or cause relatively brief diarrhea. But a few particularly nasty strains, such as E. coli O157:H7, can cause severe abdominal cramps, bloody diarrhea and vomiting. You may be exposed to E. coli from contaminated water or food â especially raw vegetables and undercooked ground beef.
Most diarrhea is due to self-limited, mild infections of the colon or small intestine. Salmonellosis: The bacteria Salmonella can contaminate food and infect the intestine. Salmonella causes diarrhea and stomach cramps, which usually resolve without treatment. Shigellosis: The bacteria Shigella can contaminate food and invade the colon. Symptoms include fever, stomach cramps, and diarrhea, which may be bloody. Travelers' diarrhea: Many different bacteria commonly contaminate water or food in developing countries.
