To characterize neutralizing antigenicity in relation to env genotypes of feline foamy virus (FeFV), serological analyses were performed using FeFV-infected cat sera and several field isolates including two env genotypes (F17- and FUV-types). Since three cats from which FeFV were isolated were found to have undetectable titers of virus neutralization (VN) antibodies, even to the homologous virus, VN antibodies were further examined with complement supplementation as an enhancement factor. With the presence of complement, the VN titers of FeFV-infected cat sera increased drastically. Although most of serum samples neutralized strains of either env genotype, sera sampled from two cats neutralized all the strains examined at similar titers, suggesting that superinfection with both env genotypes of FeFV might have occurred in the two cats. Further, we produced a monoclonal antibody (mAb) specifically neutralizing FeFV strains of FUV-type. The mAb was shown to have higher affinity to an epitope on Env of FUV-type than that of F17-type by immunoprecipitation assay. This study supplies basic information important for studies on FeFV vector development as well as on the relationship between the virus and the host immune response.
