New insights into the bacteria that cause food poisoning

[ad_1]

Recently, provision spp. which has been detected in patients with gastroenteritis, and is similar to enterohemorrhagic Escherichia coli. O157 and Salmonella spp., has attracted attention as a causative agent of food poisoning. For children with low immunity, food poisoning can be lethal as it causes severe symptoms such as diarrhea and dehydration, thus highlighting the source of infection and pathogenic factors of the disease. provision spp., and establishing prevention methods is an urgent problem worldwide.

A joint research group led by Professor Shinji Yamasaki, Dr. Sharda Prasad Awasthi, Specially Appointed Lecturer, and graduate student Jayedul Hassan of the Graduate School of Veterinary Science, Osaka Metropolitan University, determined how pathogenic genes in some provision spp. like providence alcalifaciens and Providencia rustigianii transferred in the bacterial cells of the genus provision. This group also explained that the pathogenic gene from providence rustigianii also transferred to other bacterial cells belonging to Enterobacteriaceae.

Professor Yamasaki concluded, “Hopefully this achievement can provide new insights in identifying infection pathways provision spp. and establishment of prevention methods for food poisoning.”

The findings were published in Infection and Immunity.
