Summary of "Occurrence, Seasonal Distribution, and Molecular Characterization of and in Shellfish ( and ) Collected in Sardinia (Italy)."

In this study, we investigated the occurrence, seasonal distribution, and molecular characterization of pathogenic vibrios in Mediterranean mussels () and grooved carpet shells () from two harvesting areas of Sardinia (Italy). Samples collected before and after depuration were submitted for qualitative and quantitative determination of spp. spp. isolates were presumptively identified by means of biochemical methods. Identification and virulence profile of and were performed by molecular methods. The prevalence of spp. in and was, respectively, 96 and 77%. The averaged enumeration (mean ± standard deviation) of spp. in samples of and collected at the harvesting time was 2.04 ± 0.45 and 2.51 ± 0.65 log CFU/g, respectively. The average contamination levels in samples collected after purification were 2.28 ± 0.58 log CFU/g () and 2.12 ± 0.67 log CFU/g (). Four potentially pathogenic isolates (tdh or trh) were recovered from grooved carpet shells samples. No isolate was tdh/trh. The presence of potentially pathogenic vibrios in Sardinian waters strengthens the need for rational purification practices under controlled conditions to guarantee the protection of consumers.
