Biotic and abiotic factors influencing in vitro growth of Escherichia coli O157:H7 in ruminant digestive contents

Article Abstract:

The gastrointestinal tract (GIT) of ruminants is the main reservoir of enterohemorrhagic Escherichia coli, which is responsible for food-borne infections in humans leading to severe kidney disease. Characterization of biotic and abiotic factors that influence the carriage of these pathogens by the ruminant would help in the development of ecological strategies to reduce their survival in the GIT and to decrease the risk of contamination of animal products.

Yersiniabactin production by Pseudomonas syringae and Escherichia coli, and description of a second yersiniabactin locus evolutionary group

Article Abstract:

The siderophore and virulence factor yersiniabactin is produced by Pseudomonas syringae and yersiniabactin was detected by high-pressure liquid chromatography (HPLC). A study gives clues about the evolution and dispersion of yersiniabactin genes and it describes methods to detect and study yersiniabactin producers even where genes have evolved.
