Abstract: Complete sequence of feline calicivirus (FCV) CH-GD strain was amplified by RT-PCR and recombinant PCR. DNAStar software was used to analyse nucleotide sequences and amino acid sequences. The homology of CH-GD strain which was isolated first in Guangdong province of China with reference strains was between 75.4% and 77.1%. It was lower than that was between reference strains(78.9% and 99.9%). There were two branches between 14 strains. CH-GD strain was in one branch and there was no evident difference in district. Analysing six regions of FCV capsid protein, the characteristic of A-F region was equal to that had been reported. Antigenicity and hydrophilicity were different from reference strains in three regions where three consecutive amino acids were variation.
