Scientists find new replicating mechanism of Salmonella bacteria

New findings by National Institutes of Health scientists could explain how Salmonella bacteria, a common cause of food poisoning, efficiently spread in people. In a study published this week in the Proceedings of the National Academy of Sciences, researchers describe finding a reservoir of rapidly replicating Salmonella inside epithelial cells. These bacteria are primed to infect other cells and are pushed from the epithelial layer by a new mechanism that frees the Salmonella to infect other cells or be shed into the intestine.

New method for detecting spores of non-proteolytic Clostridium botulinum

The Institute of Food Research has collaborated in the development of a new method for detecting spores of non-proteolytic Clostridium botulinum. This bacterium is the major health hazard associated with refrigerated convenience foods, and these developments give the food industry and regulators more quantitative information on which to base the procedures that ensure food safety.

Researchers to develop vaccine for plague

Given the many pressing concerns of the day, fear of plague probably isn't what causes most Americans to lose sleep. But for those whose responsibility it is to combat bioterrorism, plague is among the highest priorities. Those charged with that mission include scientists like medical researcher Steve Smiley, whose lab at the Trudeau Institute is working to develop a vaccine that will protect the public against weaponized forms of plague.
