Abstract

In this study, the prevalence of various enteric viruses in Mytilus galloprovincialis (Mediterranean mussel) belonging to class A and class B mollusc-harvesting areas in the Campania region in southern Italy was evaluated. One hundred and eight mussels were analysed using real-time reverse transcription PCR during a 2-year collection period (2014–2015) to detect the following viruses: human norovirus (genogroups I and II), rotavirus, astrovirus, sapovirus, aichivirus, hepatitis A virus and hepatitis E virus. Overall, 50.93% of mussels were contaminated by at least one of the tested viruses. Of these virus-positive mussels, 63.63% were contaminated by two or more viruses. In 2014, only three of the eight investigated viruses were detected: astrovirus, sapovirus and aichivirus, whereas in 2015, seven of the eight viruses were detected (only hepatitis E virus was not identified). Astrovirus was the most frequently detected virus in both sampling periods. In 2014, sapovirus was detected at the same frequency as astrovirus (16.00%), followed by aichivirus (8%). In 2015, astrovirus (32.53%) was most frequently detected, followed by norovirus GII (26.50%), sapovirus (18.07%), hepatitis A virus (16.87%), rotavirus (16.87%), aichivirus (13.25%) and norovirus GI (12.05%).This study describes, for the first time, the presence of aichivirus and sapovirus in mussels in Italy.
