Abstract

Feces obtained from 204 domestic cats with gastrointestinal symptoms were genetically examined for feline astrovirus (FeAstV) and feline parvovirus (FPV), both of which are known feline gastroenteric viruses. FeAstV detection rates were significantly higher in winter (44.4%) than in other seasons, and in cats under a year old (27.8%) than in a year or older ones (12.4%) (P<0.05). In contrast, no significant seasonal and age differences were obtained in FPV detection rates. Upon FeAstV ORF2 sequence analysis, the 23 present isolates were classified into the same clade (Mamastrovirus 2) as the 18 reference strains from other countries. Our findings suggest that FeAstV is already circulating in Japan, and it is more prevalent in juvenile cats in winter, unlike FPV.
