Results for different samples evaluated by an IFA and PCR. a IFA for identifying DF-1 cells infected with viral isolates using the monoclonal antibody 5D3; A, DF-1 cells infected with an isolate; B, noninfected DF-1 cells. b PCR results for the env genes of the isolates. Lane 1: 1-kb DNA marker; Lane 2: positive control; Lane 3: negative control; Lane 4–13: amplified env genes from samples 1–10, respectively
