The biovars and serovars of 57 strains of Pasteurella haemolytica(P haemolytica) isolated from pneumonic calves and goats were investigated. The biovars were determined some biochemical and cultural properties and susceptibility to penicillin. All 57 isolates were considered to correspond to biovar A. Among 57 P haemolytica, 39 isolates of them(68.4%) were serovar 1.2(3.5%) were serovar 5 and 2(3.5%) were serovar 7, the remaining 14 isolates(24.6%) were untypable.
