An avidin-biotin-peroxidase immunoperoxidase staining method was adapted for detection of peste depetitis ruminate virus antigen in impression smears of ocular, buccal, nasal and rectal swabs and tissue impressions from experimentally infected goats. Positive staining was demonstrated in 84% out of 100% swabs smears and 77% of 100 tissue impressions. The test is recommended for use in any PPR surveillance programme.
