    Abstract:
    Shellfishes are a significant economic and nutritious seafood amongst people in different countries. Seafood products, particularly shellfish, are potential reservoirs of enteric viruses. This research investigated the incidence of rotavirus (RoV), norovirus (NoV) GI and GII, hepatitis A virus (HAV), and hepatitis E virus (HEV) in shellfish samples from the Persian Gulf, Iran. One hundred and fifty shellfish samples were collected. RNA extraction and cDNA synthesis were performed using commercial kits. The real-time polymerase chain reaction assessed the presence of enteric viruses in extracted cDNA samples. Thirty-two out of 150 (21.33%) shellfish samples were contaminated with enteric viruses. Prevalence rates of NoV GI, NoV GII, HAV, and RoV amongst shellfish samples were 8.00%, 11.33%, 1.33%, and 0.66%, respectively. There were no contaminated shellfish samples with HEV. Simultaneous prevalence of HAV and NoV GI, and HAV and NoV GII viruses were 0.66% and 0.66%, respectively. Examined viruses had a higher prevalence in shellfish samples collected in the winter season (P<0.05). Prevalence of HAV, RoV, NoV GI, and NoV GII amongst shellfish samples gathered in the winter season was 2.85%, 9.09%, 11.90%, and 20%, respectively. To the best of our knowledge, this was the first report of the incidence of enteric viruses, particularly HAV, NoV GI, NoV GII, and RoV, in shellfish samples from the Persian Gulf, Iran. Shellfish samples may serve as a potential source of enteric viruses for the human population. Therefore, routine viral assessments should be conducted. The consumption of fully cooked shellfish can significantly reduce the risk of HAV, RoV, NoV GI, and NoV GII infections. Furthermore, given the export value and importance of shellfish samples, their microbial quality and safety should be routinely monitored.
