Key result
A feline calicivirus isolate (W109-1443) was identified from a road-killed leopard cat in Taiwan, sharing 81.7% sequence identity with a Chinese domestic cat strain and belonging to genogroup II.

The identification of a recombinant genogroup II feline calicivirus in a wild leopard cat in Taiwan highlights the potential for pathogen transmission between domestic and wild felids.
May indicate FCV spillover to endangered leopard cats; leaves open recombination dynamics in genogroup II strains.
The leopard cat (Prionailurus bengalensis) is an endangered wildlife that is protected under Taiwan's regulations. The body of a road-killed leopard cat was found to contain sequences of feline calicivirus (FCV), designated W109-1443. Analysis of the complete genomic sequence revealed that it shared approximately 81% similarity with a Chinese strain of FCV found in a domestic cat. Phylogenetic analysis of the VP1 gene indicated that the W109-1443 isolate belonged to genogroup II. Recombination analysis revealed that the W109-1443 isolate may have resulted from recombination between two FCV strains. Given the potential impact of FCV on the health and survival of wild felids, further investigation is necessary to assess its pathogenicity in the leopard cat population.

Chen et al. (2024) conducted a case report in Feline calicivirus infection (n=1). Feline calicivirus (FCV) detection was evaluated on Genomic characterization of FCV. A feline calicivirus isolate (W109-1443) was identified from a road-killed leopard cat in Taiwan, sharing 81.7% sequence identity with a Chinese domestic cat strain and belonging to genogroup II.
