Research – NIH scientists study salmonella swimming behavior as clues to infection

NIH

Salmonellaa

Salmonella enterica serovar Typhimurium bacteria (S. Typhimurium) commonly cause human gastroenteritis, inflammation of the lining of the intestines. The bacteria live inside the gut and can infect the epithelial cells that line its surface. Many studies have shown that Salmonella use a “run-and-tumble” method of short swimming periods (runs) punctuated by tumbles when they randomly change direction, but how they move within the gut is not well understood.

National Institutes of Health scientists and their colleagues believe they have identified a S. Typhimurium protein, McpC (Methyl-accepting chemotaxis protein C), that allows the bacteria to swim straight when they are ready to infect cells. This new study, published in Nature Communications, describes S. Typhimurium movement and shows that McpC is required for the bacteria to invade surface epithelial cells in the gut.

The study authors suggest that McpC is a potential target for developing new antibacterial treatments to hinder the ability of S. Typhimurium to infect intestinal epithelial cells and colonize the gut. National Institute of Allergy and Infectious Diseases scientists at Rocky Mountain Laboratories in Hamilton, Montana, led the study. Collaborators included groups from the University of Texas A&M campuses in College Station and Kingsville.

Singapore – Eng’s Heritage at Northpoint suspended after 26 people had food poisoning

Yahoo News

Authorities have suspended the licence of Eng’s Heritage from Wednesday (13 January) until further notice, after 26 people who ate at the wonton noodle chain’s Northpoint outlet came down with food poisoning.

Five of the 26 cases are currently hospitalised and are in a stable condition, while one additional case has been discharged from hospital, the Ministry of Health (MOH) and the Singapore Food Agency (SFA) said in a joint release.

The patrons reportedly had gastroenteritis symptoms after they consumed food at the outlet between 7 and 9 January, MOH and SFA added.

All food handlers working in the suspended premises are required to re-attend and pass the Basic Food Hygiene Course, before they can resume work as food handlers.

The appointed food hygiene officers working at the suspended premises are also required to re-attend and pass the food hygiene officer course before they can resume work.
