Analysis of the capsid protein gene of a feline calicivirus isolated from a dog.

The authors report the sequence analysis of the capsid protein-encoding gene (ORF2) of a calicivirus strain recently isolated in Italy from a pup with enteritis. Sequence comparison and phylogenetic analysis revealed that the isolate is highly similar to field and reference feline caliciviruses (FCVs). The isolation of a feline-like calicivirus and the results of recent serological investigations suggest that FCV infection frequently occurs in dogs, but the consequences of this interspecies infection in the canine host are still unknow
