Norovirus genotypes present in oysters and in effluent from a wastewater treatment plant during the seasonal peak of infections in Ireland in 2010.

ABSTRACT: We determined norovirus (NoV) concentrations in effluent from a wastewater treatment plant and in oysters during the peak period of laboratory-confirmed cases of NoV infection in Ireland in 2010 (January to March). Weekly samples of influent, secondary treated effluent, and oysters were analyzed using real-time quantitative reverse transcription-PCR for NoV genogroup I (GI) and genogroup II (GII). The mean concentration of NoV GII (5.87 × 10(4) genome copies 100 ml(-1)) in influent wastewater was significantly higher than the mean concentration of NoV GI (1.40 × 10(4) genome copies 100 ml(-1)). The highest concentration of NoV GII (2.20 × 10(5) genome copies 100 ml(-1)) was detected in influent wastewater during week 6. Over the study period, a total of 931 laboratory-confirmed cases of No
