Description

<jats:p>Between 2001 and 2005, 207 raw sewage samples were collected at the inflow of a sewage treatment plant in Aichi Prefecture, Japan. Of the 207 sewage samples, 137 (66.2 %) were found to be positive for amplification of Aichi virus (AiV) nucleotide using reverse transcription (RT)-PCR with 10 forward and 10 reverse primers in the 3D region corresponding to the nucleotide sequence of all kobuviruses. AiV genotype A sequences were detected in all 137 samples. New sequences of AiV were detected in nine samples, exhibiting 83 % similarity with AiV A846/88, but 95 % similarity with canine kobuvirus (CKV) US-PC0082 in this region. The nucleotide sequences from the VP3 region to the 3′ untranslated region (UTR) of sewage sample Y12/2004 were determined. The number of nucleotides in each region was the same as that of CKV. The similarity of the nucleotide (amino acid) identity of a complete VP1 region was 90.5 % (94.8 %) between Y12/2004 and CKV US-PC0082. The phylogenic analyses based on the nucleotide and the deduced amino acid sequences of VP1 and 3D showed that Y12/2004 was independent from AiV, but closely related to CKV. These results suggested that CKV is present in Aichi Prefecture, Japan.</jats:p>
