Scientists have used a new method to map the response of every salmonella gene to conditions in the human body, providing new insight into how the bacteria triggers infection. In a world first, the scientists exposed salmonella to 22 lab environments that mimic conditions that the bacterium finds when it enters the human body and discovered the effects of these conditions on individual genes in the bacteria. After people eat salmonella, the microbes enter the stomach, and intestine, and...

The potentially deadly bacterium Salmonella possesses a molecular machine that marshals the proteins it needs to hijack cellular mechanisms and infect millions worldwide. In a paper published Feb. 3 online in Science Express, Yale University researchers describe in detail how Salmonella, a major cause of food poisoning and typhoid fever, is able to make these proteins line in up in just the right sequence to invade host cells. "These mechanisms present us with novel targets that might form...

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...

Salmonella enterica is a subspecies of Salmonella enterica, the rod shaped, flagellated, aerobic, Gram-negative bacterium. It is a member of the genus Salmonella and many of the pathogenic serovars of the S. enterica species are in this subspecies. Serovars can be designated fully or in a shortened form. The genus, Salmonella, is on the short form lists which are followed by the capitalized and non-italicized serovar. Each serovar can have many strains as well, which allows for a rapid...
