Scientists have looked at why humans infected with E. coli are more likely to suffer serious symptoms after studying toxins produced by the bacteria.
The team found that a toxin produced by naturally-occurring E. coli helps the bacteria colonize the intestinal tract of cattle and increases the transmission of the

A revision of Shiga-toxin producing E. coli guidelines in Norway was helped by a survey and new scientific evidence.
In autumn 2016, Shiga-toxin producing E. coli (STEC) guidelines were modified accounting for evidence on the association between hemolytic uremic syndrome (HUS) and virulence profile of STEC strains.
The revised guidelines

Researchers have looked at why dangerous forms of E. coli keep appearing in cattle.
While E. coli bacteria are a known cause of food poisoning, a wide variety of strains exist, many of them are harmless and can be found in the intestines of humans. However, ingestion of harmful strains

Scientists at USDA’s Agricultural Research Service Western Regional Research Center in Albany, CA, have come up with a less-expensive way to detect biologically active Shiga toxin, a product of pathogenic Escherichia coli serotype O157:H7. 
It is estimated that E. coli O157:H7 causes 73,000 cases of food poisoning and more than

A growing reliance on new, cheaper and faster testing for infectious diseases has experts questioning the accuracy of a reported decline of E. coli O157 cases in the U.S., challenging one of the nation’s few food safety success stories.
Rather than identifying the specific strain of E. coli, such as

According to the CDC, E. coli O157:H7 causes 73,000 illnesses and 50 deaths every year in the United States. Another six E. coli strains – O26, O45, O111, O121, O145, and O103 – are considered less pervasive, sickening “only” an estimated 37,000 people a year and killing nearly 30. E.
