A phenotypic characterisation of 150 isolates of bacteria previously identified as Pasteurella multocida was performed. All the isolates had been obtained from Australian pigs in the three eastern States of Queensland (110 isolates), New South Wales (21 isolates) and Victoria (19 isolates). Seven different biochemical biovars were recognised amongst the isolates. A total of 100 isolates (67%) were assigned to biovar 3, previously shown to be the most common biovar in isolates of P. multocida from Australian poultry [Fegan, N., Blackall, P.J., Pahoff, J.L., 1995. Phenotypic characterisation of Pasteurella multocida isolates from Australian poultry. Vet. Microbiol., 47, 281-286.]. Six of the seven biovars, including biovar 3, were identified as P. multocida subsp. multocida, 124 isolates in total. One other biovar, consisting of thirteen isolates, was identified as P. multocida subsp. gallicida. Within the six biovars that were identified as P. multocida subsp. multocida, biovars 12, 13 and 14 represented unusual biochemical variants. The nine isolates assigned to biovar 12 appeared to be lactose positive variants of P. multocida subsp. multocida. The three isolates in biovar 13 appeared to be ornithine decarboxylase (ODC) negative variants of P. multocida subsp. multocida. The single isolate in biovar 14 appeared to be an ODC negative, lactose positive variant of P. multocida subsp. multocida.
对先前鉴定为多杀性巴氏杆菌的150株细菌进行了表型特征分析。所有分离株均来自澳大利亚东部三个州的猪，其中昆士兰州有110株，新南威尔士州有21株，维多利亚州有19株。在这些分离株中识别出了7种不同的生化生物变种。共有100株分离株（67%）被归为生物变种3，该变种先前已被证明是澳大利亚家禽多杀性巴氏杆菌分离株中最常见的生物变种[费根，N.，布莱考尔，P.J.，帕霍夫，J.L.，1995年。澳大利亚家禽多杀性巴氏杆菌分离株的表型特征分析。《兽医微生物学》，47，281 - 286页]。7种生物变种中的6种，包括生物变种3，被鉴定为多杀性巴氏杆菌多杀亚种，总共124株。另一种生物变种由13株分离株组成，被鉴定为多杀性巴氏杆菌鸡亚种。在被鉴定为多杀性巴氏杆菌多杀亚种的6种生物变种中，生物变种12、13和14代表不寻常的生化变体。归为生物变种12的9株分离株似乎是多杀性巴氏杆菌多杀亚种的乳糖阳性变体。生物变种13中的3株分离株似乎是多杀性巴氏杆菌多杀亚种的鸟氨酸脱羧酶（ODC）阴性变体。生物变种14中的单株分离株似乎是多杀性巴氏杆菌多杀亚种的ODC阴性、乳糖阳性变体。
