Use of the indirect fluorescent antibody test in the detection of bovine respiratory syncytial virus antibodies in bovine serum.
The indirect fluorescent antibody test was adapted for identifying bovine respiratory syncytial virus and its specific antibody, using goat turbinate (GTU) cells. The virus caused maximal cytopathic effects in GTU cells 4 to 8 days postinfection, but fluorescence was not readily detected during this period. Fluorescence was maximal in infected GTU cells at 24 to 36 hours postinfection, but could be detected 48 hours postinfection. Bovine serums (331) which had been submitted to the Oklahoma Animal Disease Diagnostic Laboratory were tested for antibodies to this virus, and 73.6% were found to be positive.
