During a 2-year study, the presence of human pathogenic bacteria and noroviruses was investigated in shellfish, seawater and/or surface sediments collected from three French coastal shellfish-harvesting areas as well as in freshwaters from the corresponding upstream catchments. Bacteria isolated from these samples were further analyzed. Escherichia coli isolates classified into the phylogenetic groups B2, or D and enterococci from Enterococcus faecalis and E. faecium species were tested for the presence of virulence genes and for antimicrobial susceptibility. Salmonella members were serotyped and the most abundant serovars (Typhimurium and its monophasic variants and Mbandaka) were genetically characterized by high discriminative subtyping methods....

Prevalence and characterization of Salmonella spp. in three shellfish-harvesting areas in France

Shellfish farming is an important economic activity in the Brittany and Normandy regions. However, a part of the production sites corresponds to relatively sensitive areas where the presence of faecal microorganisms is a major concern for shellfish and constitutes a possible health risk. Indeed, shellfish bioaccumulates in their tissues pathogenic contaminants present in water and can cause food-borne diseases such as salmonellosis. During a two-year study, we evaluated the presence of faecal indicators, measured the prevalence of Salmonella spp., isolated and characterized Salmonella spp. from three French shellfish-harvesting areas (shellfish and sediment) and their watersheds (from river water samples).

Successful detection of pathogenic Shiga-toxin-producing Escherichia coli in shellfish, environmental waters and sediment using the ISO/TS-13136 method
Provedor de dados: 5
Autores: Baliere, Charlotte; Rince, Alain; Thevenot, Delphine; Gourmelon, Michele.
The presence of highly pathogenic Shiga-toxin-producing Escherichia coli (STEC) in shellfish, upstream waters and sediment from coastal shellfish sites was evaluated using the ISO/TS-13136 method. Shellfish (oysters, mussels and cockles), water and sediment samples were collected monthly over a period of 1 year. The method used real-time PCR detection of stx1, stx2 and eae genes and genetic markers corresponding to the five major serogroups (O157, O26, O103, O111 and O145) on enrichment broths and the identification of STEC when these genes and markers were detected. stx genes were detected in the broth of 33% of shellfish batches (n = 126), 91% of water samples (n = 117) and 28% of sediment (n = 39). One stx1+, eae+ O26:H11 strain was isolated from a...
