Researchers have detected a highly virulent new form of pathogenic Listeria monocytogenes.

It was identified as the cause of serious diseases in sheep in a remote area of the Chinese province Jiangsu.

An international research group led by the Institute of Medical Microbiology at the Justus Liebig University Giessen (JLU)

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

Scientists have found the virulence of Listeria differs depending on the food type, discovering that dairy products are contaminated with the most virulent bacteria.

Researchers from the Pasteur Institute, the French National Institute of Health and Medical Research (Inserm), and the University of Paris said the discovery paves the way

Future Salmonella outbreaks are likely to become more severe, according to researchers from an Australian university.

The team from the University of Sydney used more than 17,000 Salmonella Typhimurium isolates collected from 2008 to 2016 to demonstrate that genetic networks of Salmonella are linked through a few degrees of separation,

Researchers at the University of Edinburgh have shown that Listeria responds to an antibiotic, despite the pathogen carrying genes that should make it highly resistant.

Their study report, published in the journal PLOS Genetics, reports that the susceptibility of the bacterium Listeria monocytogenes to the antibiotic is complex and

Could identifying certain hypervirulent subtypes of Salmonella be a first step toward preventing food poisoning outbreaks caused by the bacteria?


An international research team, led by University of California Santa Barbara researchers Michael Mahan and Douglas Heithoff, thinks so and has detailed its findings in a paper titled “Intraspecies Variation
