%X Parvoviruses are ubiquitous pathogens that cause fatal disease in cats. Feline panleukopenia virus (FPV) is a primitive virus reported first and canine parvovirus (CPV) evolved from FPV and was reported later. Both induce disease in cats and dogs with correlative signs. FPV in domestic cats is genetically diverse and some strains may differ from those used for vaccination. In this study, a virus of FPV strain, ABT/MVC/2022/FPV/001, was identified from a fecal sample of the suspected cat with severe haemorrhagic gastroenteritis. The phylogenetic analysis and complete genome sequence of the strain share 99.75% nucleotide identity with FPV variant MH559110 belonging to Tamil Nadu, India. The results also reveal similarities to strains isolated from Italy, Belgium, and China. The deduced amino acid sequence of isolated strain revealed specific amino acid substitution (Pro5Ala, Phe6Val, His7Gln, Asn9Asp, Lys16Arg, Lys19Arg, Asn52Lys, Gly58Trp, Thr66Ser, Lys67Arg, Leu70His, Asn373Asp and Ala390Thr) which differed from MH559110 and other strains. The complete genomic analysis revealed that the FPV strain circulating in India is evolving rapidly with unique antigenic variations between field FPV, CPV and vaccine strains which may be the major cause for vaccine failure in vaccinated cats.
