(Submitter supplied) Foodborne illness from contaminated fresh produce has increased over the past decade, with the enteric human pathogen Salmonella enterica being frequently implicated in foodborne illness outbreaks associated with tomato consumption. Our previous work demonstrated that Salmonella responds to tomato cultivar differences, but knowledge of the underlying genetic responses is limited. To identify the mechanisms permitting this human pathogen-plant commodity association, a genome-wide transcriptomic analysis of Salmonella on tomato shoots and roots was conducted using an RNA-seq approach. more...

(Submitter supplied) Salmonella Heidelberg is currently the 9th common serovar and has more than twice the average incidence of blood infections in Salmonella. A recent Salmonella Heidelberg outbreak in chicken infected 634 people during 2013-2014, with a hospitalization rate of 38% and an invasive illness rate of 15%. While the company’s history suggested longstanding sanitation issues, the strains’ characteristics which may have contributed to the outbreak are unknown. more...

(Submitter supplied) Salmonella enterica var. Typhimurium (S. Typhimurium) is a Gram-negative, facultative intracellular pathogen that infects the intestinal tracts of humans and animals. In the host, S. Typhimurium encounters a wide range of oxygen concentrations going from oxic conditions in the stomach to near anoxic conditions in the distal sigmoid colon-rectal junction. In Escherichia coli, FNR (Fumarate Nitrate Reductase) is one of the main regulatory proteins involved in oxygen sensing and in controlling the transcription of the genes required for the aerobic/anaerobic transition.. more...
