Insights into the bacteria that induce foodborne illness 2023

The characteristics of a certain type of food-poisoning bacteria were discovered by researchers, which paved the way for the creation of preventative techniques.

Journal of Infection and Immunity was the publication that ultimately made the findings public.

Providencia spp., which has been found in individuals suffering from gastroenteritis and is very similar to enterohemorrhagic Escherichia coli O157 and Salmonella spp., has received a lot of attention as a potential cause of food poisoning as of late.

Food poisoning can be fatal for children with a poor immune system since it produces severe symptoms such as diarrhea and dehydration.

Understanding Providencia spp.’s infection source and pathogenic factors

A joint research group led by Professor Shinji Yamasaki, Dr. Sharda Prasad Awasthi, a Specially Appointed Lecturer, and graduate student Jayedul Hassan from the Graduate School of Veterinary Science at Osaka.

Metropolitan University discovered how the pathogenic genes in some Providencia spp., including Providencia alcalifaciens and Providencia rustigianii, are transferred within the bacterial cells of the genus Providencia.

The researchers have also uncovered evidence that the harmful genes of Providencia rustigianii may be transmitted to the cells of other bacteria that belong to the family Enterobacteriaceae.

Professor Yamasaki came to the conclusion that “this achievement is expected to provide new insights into the identification of infection routes of Providencia spp. and the establishment of preventive methods for food poisoning.”
