Research by scientists in Australia could help open up new possibilities to treat enterohemorrhagic E. coli (EHEC) infections.

University of New South Wales (UNSW) microbiologists discovered a molecular pathway that controls Shiga toxin production. The findings were published in the journal Proceedings of the National Academy of Sciences (PNAS).

Contaminated blood from slaughterhouse pigs infected with hepatitis E could be reaching the human food supply chain, according to researchers.

“. . . 40 percent of U.S. slaughterhouse pigs (sampled) were seropositive for HEV (hepatitis E virus), indicating prior HEV infection of the pigs on the farms, which was consistent

Infections from a lesser-known foodborne pathogen most commonly associated with infants may be more common in elderly populations — and even adults and adolescents — than previously thought, according to a new study by researchers at the U.S. Centers for Disease Control and Prevention. The study, set to be published

A study from the Emerging Infections Program at Yale School of Public Health found that, in adults, campylobacteriosis is more common among those of higher socioeconomic status, but, for children younger than 10, more cases occurred among those of lower socioeconomic status. Researchers Kelley Bemis, Ruthanne Marcus and James Hadler

A developing threat to the effectiveness of antibiotics are carbapenemases — enzymes that allow bacteria to break down carbapenem-class antibiotics, thereby developing resistance. What’s most troubling about carbapenemase-producing organisms is that they are resistant to most other classes of antibiotics as well. Carbapenems are used as a last resort. Infections
