Abstract

Nine fetuses and neonates from sheep and goats in Egypt were screened for pestiviruses using immunohistochemistry (IHC), virus isolation, and reverse transcription-polymerase chain reaction (RT-PCR). Two goat kids with typical border disease (BD) were positive for pestivirus infection by immunohistochemistry (IHC) using polyclonal anti-BDV serum but not when four different monoclonal antibodies (MAbs) were used. On inoculation in MDBK cells, a cytopathic bovine viral diarrhoea virus (BVDV) was isolated from one of the two kids. PCR amplification followed by sequencing of the 5′-UTR region confirmed it as BVDV subtype 1b. Although the circulating virus in Egypt is considered to be BVDV 1a, this report confirms the existence of BVDV 1b in addition to BVDV 1a. To our knowledge, this is the first report of isolation of a pestivirus from goats in Egypt and is probably the second report worldwide of a goat kid showing central nervous signs associated with border disease.
