Persistence of human Aichi virus infectivity from raw surface water to drinking water.

ABSTRACT: Human Aichi virus 1 (AiV-1) is a water- and food-borne infection-associated picornavirus that causes gastroenteritis in humans. Recent studies on environmental waters showed a high frequency and abundance of AiV-1, suggesting that it might be an appropriate indicator of fecal contamination. We screened 450 surface and drinking water samples from a Tunisian drinking water treatment plant (DWTP) and the Sidi Salem dam for AiV-1 by real time reverse transcriptase PCR (RT-qPCR). The persistence of infectious particles was evaluated using an integrated cell culture approach coupled with quantitative molecular detection (ICC-RT-qPCR). In all, 85 (18.9%) water samples were positive for AiV-1 with viral loads ranging from 0.47 to 11.62 log₁₀ cp/L and a median of 4.97 log₁₀ cp
