Detection and characterization of Bifidobacterium crudilactis and B. mongoliense able to grow during the manufacturing process of French raw milk cheeses.

Background: The study of a production chain of raw milk cheeses (St Marcellin, Vercors area, France) led to the isolation of two Bifidobacterium populations: B. crudilactis and B. mongoliense, that were able to grow along the production chain.

Antimicrobial resistance in the food chain: a review.

Antimicrobial resistant zoonotic pathogens present on food constitute a direct risk to public health. Antimicrobial resistance genes in commensal or pathogenic strains form an indirect risk to public health, as they increase the gene pool from which pathogenic bacteria can pick up resistance traits. Food can be contaminated with antimicrobial resistant bacteria and/or antimicrobial resistance genes in several ways.

Validation of a method for simultaneous isolation of Shiga toxin-producing Escherichia coli O26, O103, O111, and O145 from minced beef by an international ring-trial.

An isolation method described by Possé et al. (FEMS Microbiol Lett 2008;282:124-131) was satisfactorily validated in an international ring-trial using artificially contaminated minced beef samples. Until now, no validated method existed for the simultaneous isolation of Shiga toxin-producing Escherichia coli serogroups O26, O103, O111, and O145 in food.
