Genetic Evolution and Biological Characteristics of Feline Caliciviruses Isolated from Dogs

Figure 5

Distribution of neutralizing antibody titers against the two canine-origin FCV isolates in dogs and vaccinated cats. Fifty canine and fifty feline serum samples with known vaccination histories were collected. The neutralizing titers were determined by using a specific virus dilution in order to assess their 50% serum neutralization endpoint.
