The particular strain (serotype) of Escherichia coliform (E. coli) bacteria that causes of tenfatal diarrhea, internal bleeding, and kidney damage in humans. Although cattle were susceptible to E. coifs toxins prior to the 1980s, they eventually developed resistance. That meant that the cattle could carry these bacteria without getting sick, and transmit E. coli 0157:H7 to humans whenever conditions allow (e.g., when E. coli 0157:H7-infected cattle are slaughtered and people consume the meat without first heating it to a high enough temperature to kill the E. coli 0157:H7). Some varieties of E. coli 0157:H7 are resistant to the antibiotics tetracycline and streptomycin.<\/p>\n
In 1996, researchers at Cornell University in New York State, U.S.A. discovered that nonambulatory cows (that could not walk) were approximately four times as likely as other cows to test positive for E. coli 0157:H7. Other research in Canada indicates that fasting of cattle (common occurrence of nonambulatory cows) tends to alter the pH inside the cow’s rumen (stomach) in a way that encourages the proliferation of E. coli 0157:H7 instead of the bacteria that normally populate the rumen.<\/p>\n
