Figure 1.
Concentration and genetic diversity of Rotavirus A (RVA) in water samples from DWTP E. The RVA NSP3 gene was quantitatively detected by real-time RT-PCR and plotted together with cases of rotavirus gastroenteritis reported for the week of sample collection in the prefecture upstream (A). Relative abundance (%) was calculated for RVA G genotypes determined by the VP7 gene (B), P genotypes determined by the VP4 gene (C), and I genotypes determined by the VP6 gene amplified in human (D) and animal (E) nested PCR assays. The value above each column of relative abundance represents the number of OTUs with > 500 reads.
