“…In agreement with these results, Ripabelli et al (11), analyzing 62 mollusc samples from the Adriatic Sea and searching for the presence of verotoxigenic Vibrio, Salmonella and E. coli, detected no Salmonella strains. Salmonella was also absent in oyster samples studied by Eyles and Davey (6).…”

“…On the other hand, Vibrio sp. was isolated from 48.4% of the samples analyzed by Ripabelli et al (11), with the most frequent species being V. alginolyticus (32.2%) and V. vulnificus (17.7%), while contamination with V. parahaemolyticus (1.6%) and V. cholerae (1.6%) was low. Eyles and Davey (6) isolated V. cholerae in 20, 30 and 11% of oysters, water and sediment samples, respectively.…”

Oysters are filter feeders able to ingest particles in suspension that may carry pathogenic microorganisms. In this respect, the consumption of raw oysters can cause foodborne diseases in humans. The aim of the present study was to evaluate the microbiological quality of Crassostrea gigas oysters cultivated and commercialized in the coastal region of Florianópolis, SC, Brazil. The study comprised counts of coliforms at 35ºC and at 45ºC, Escherichia coli and coagulase-positive staphylococci, and detection of Salmonella sp, Vibrio cholerae and Vibrio parahaemolyticus. Ninety samples were analyzed, 45 of them collected at seafood commercial establishments and the other 45 were collected in the cultivation area. All analyses were performed according to methods of the American Public Health Association. Vibrio cholerae, V. parahaemolyticus and Salmonella sp. were not detected in any of the samples. Coagulase-positive staphylococci were observed in only one sample (80 CFU/g). The counts of coliforms at 35 and 45ºC indicated that samples obtained from both the cultivation area and place of sale were contaminated. E. coli was detected in 4 (9%) samples collected in the cultivation area and in 16 (35.5%) samples obtained from commercial establishments. These results indicate the need for monitoring the quality of raw oysters, including the implantation of programs for good mollusk manipulation and management practices.

“…For example, Vibrio and other pathogenic bacteria were frequently found in M. galloprovincialis [17,18]. Among those pathogens, Vibrio species have been demonstrated to be an important cause of diseases in shellfish [19], which could induce cytotoxicity and the production of reactive oxygen (ROS), etc.…”

a b s t r a c tHeat shock 70 kDa protein 12A (HSPA12A) is an atypical member of HSP70 family, and the translationally controlled tumor protein (TCTP) is a novel HSP with chaperone-like activity. They are both involved in protecting organisms against various stressors. In the present study, the cDNAs of HSPA12A and TCTP (called MgHSPA12A and MgTCTP) were identified from Mytilus galloprovincialis by RACE approaches. The full-length cDNA of MgHSPA12A and MgTCTP encoded a peptide of 491 and 171 amino acids, respectively. Real-time PCR was employed to analyze the tissue distribution and temporal expression of these two genes after bacterial challenge and cadmium (Cd) exposure. It was found that the transcripts of MgHSPA12A and MgTCTP were dominantly expressed in gonad and muscle, respectively. The expression level of MgTCTP at 48 h post Vibrio anguillarum challenge was detected to be significantly up-regulated in hepatopancreas (P < 0.05). As concerned to Cd exposure, 2.0-fold increase of MgHSPA12A expression compared to that of the control was observed at 48 h in 5 mg/L Cd 2þ -treated group, while the expression levels of MgTCTP were significantly decreased after exposed to both 5 and 50 mg/L Cd 2þ for 24 h and 96 h.These results suggested the potential involvement of MgHSPA12A and MgTCTP in the mediation of the immune responses and environmental stress in mussels.
