Genetic diversity, pathogenicity, and serological cross-neutralization characteristics of contemporary feline calicivirus isolates from China.
Feline calicivirus (FCV) shows extensive genetic and antigenic diversity and typically causes oral-respiratory disease (ORD), although some isolates are associated with virulent systemic disease (VSD). The molecular basis of FCV-associated VSD remains unclear and cannot be attributed to a single VP1 residue, phylogenet...
