| Abstract: | A viral agent was isolated from the trachea of a lamb that was suffering from a respiratory disorder. The physical and chemical properties of the isolates are characteristic of the herpesvirus group. It contains DNA in its virion, is ether sensitive, acid labile at pH 3.0 and heat labile at 56 degrees C after five minutes. The cytopathology observed provided further evidence of a herpesvirus isolate. The neutralization of the infectivity of the isolate with antiserum to bovine herpesvirus 1 is evidence that it should be considered an isolate of bovine herpesvirus 1. It is concluded that this is a report of a bovine herpesvirus infection in sheep. |
