Titers of anti-PIV5 antibodies in the PIV5-vaccinated dogs.

<p>Eight dogs which had been vaccinated with live PIV5 were immunized with one dose of 8×10⁷ PFU of rPIV5-H3 viruses in 1 mL or PBS via intranasal route. The dogs were divided into two groups: two dogs received PBS; The remaining six dogs received rPIV5-H3. Blood samples were collected at 0 and 21 days post infection for ELISA (A) and viral neutralization antibody assay (B). Data were presented as average value of duplicate wells. In the neutralization antibody assay, the white column indicates the PIV5 nAb titer is equal to or higher than 10.
