The Laboratory includes three National Reference Centers (CNR) and a WHO Collaborating Center. All modern aspects of bacterial biodiversity are considered with the purposes of designing new tools for molecular identification and typing of foodborne bacterial pathogens of concern.
National Reference Center for Salmonella . CNR-Salm contributes to the surveillance of salmonellosis in France by performing serotyping of 8-10,000 clinical isolates each year. CNR-Salm also performs fine molecular fingerprinting (PFGE, MLVA, MLST). CNR-Salm develops new subtyping methods (CRISPR polymorphism), and monitors antimicrobial resistance and the underlying molecular mechanisms. CNR-Salm has developed collaborations with prestigious teams working on population genetics and genome projects of serotypes Typhi and Paratyphi A, agents of typhoid and paratyphoid fevers.
National Reference Center for Escherichia coli-Shigella. CNR-coli participates in the surveillance of shigellosis and infections due to shigatoxin-producing E. coli (haemorrhagic colitis and haemolytic and uremic syndromes). E. coli strains are analyzed by serotyping (classical and molecular), PFGE and virulence gene content. CNR-coli develops new subtyping methods (CRISPR polymorphism, MLVA), and monitors antimicrobial resistance and the underlying molecular mechanisms.
National Reference Center for Vibrios and cholera. CNR- Vibrio participates in the surveillance of cholera and non-cholera Vibrio infections in France and collaborates with foreign countries subject to cholera outbreaks and with humanitarian non-governmental organizations. Vibrio strains are identified by phenotypical and molecular (rpoB, rrs) methods, serotyping, and virulence gene content. CNR- Vibrio also performs molecular fingerprinting (PFGE and ribotyping). It is involved in control of food-borne and water-borne contamination by Vibrio species of medical interest and develops methods improving detection and quantification of pathogenic Vibrio strains.
WHO Collaborating Center for Salmonella . WHOCC for Salmonella maintains and updates the White-Kauffman-Le Minor scheme, which lists all known Salmonella antigenic formulae. Characterization of all serotypes by MLST and flagellin genes is ongoing.
