Abstract: | Shellfish are recognized as a potential vehicle of viral disease and despite the control measures for shellfish safety there is periodic emergence of viral outbreaks associated with shellfish consumption. In this study a total of 81 mussel samples from Ría do Burgo, A Coruña (NW Spain) were analysed. Samples were collected in seven different harvesting areas with the aim to establish a correlation between the prevalence of norovirus (NoV) and hepatitis A virus (HAV) in mussel samples and the water quality. In addition, the genogroup of the detected HAV and NoV strains was also determined. The HAV presence was detected in 18.5 % of the samples. Contamination levels for this virus ranged from 1.1 × 102 to 4.1 × 106 RNA copies/g digestive tissue. NoV were detected in 49.4 % of the cases reaching contamination levels from 5.9 × 103 to 1.6 × 109 RNA copies/g digestive tissue for NoV GI and from 6.1 × 103 to 5.4 × 106 RNA copies/g digestive tissue for NoV GII. The χ²-test showed no statistical correlation between the number of positive samples and the classification of molluscan harvesting area based on the E. coli number. All the detected HAV strains belong to genogroup IB. NoV strains were assigned to genotype I.4, II.4 and II.6. |
