Reoviruses are a common class of enteric viruses capable of
infecting a broad range of mammalian species, typically with low pathogenicity. Previous studies have shown that reoviruses are common
in raw water sources and are often found along with other animal
viruses. This suggests that in addition to the commonly monitored
enteroviruses, reoviruses might serve as an informative target for
monitoring fecal contamination of drinking water sources. Mammalian
reoviruses were detected and identified by a combined cell
culture-reverse transcription-PCR (RT-PCR) assay with novel primers
targeting the L3 gene that encodes the

Detection and Identification of Mammalian Reoviruses in Surface
Water by Combined Cell Culture and Reverse Transcription-PCR
3 major core protein. Five of
26 (19.2%) cytopathic effect-positive cell culture lysates inoculated
with surface water were positive for reoviruses by RT-PCR. DNA sequence
analysis of RT-PCR products revealed significant sequence diversity
among isolates, which is consistent with the sequence diversity among
previously characterized mammalian reoviruses. Sequence analysis
revealed persistence of a reovirus genotype at a single sampling site,
while a sample from another site contained two different reovirus genotypes.
