Between March and July 1987, a study was undertaken to determine the prevalence of and factors associated with toxigenic type D Pasteurella multocida infection in New South Wales pig herds. Toxigenic type D P. multocida was isolated from the nasal cavities of pigs in one (2%) of 50 randomly selected herds. Toxigenic isolates were also recovered from 2 (8%) of a separate group of 25 herds that had purchased pigs from a known infected piggery in South Australia (herd SA). Snout abnormalities were present in 9.4%, 3.2% and 1.8% of grower pigs in the 3 affected herds. Isolation of toxigenic P. multocida was significantly associated (p less than 0.0001) with the occurrence of clinically affected pigs in the herd. Purchase of at least 5 pigs from herd SA was associated with an elevated risk (p less than 0.05) of isolation of toxigenic P. multocida.
1987年3月至7月期间，开展了一项研究，以确定新南威尔士州猪群中产毒素D型多杀性巴氏杆菌感染的流行情况及相关因素。从50个随机选择的猪群中的1个（2%）猪群的猪鼻腔中分离出了产毒素D型多杀性巴氏杆菌。在另外一组25个从南澳大利亚一个已知受感染猪场（SA猪场）购买过猪的猪群中，也有2个（8%）猪群分离出了产毒素菌株。在3个受影响猪群的生长育肥猪中，分别有9.4%、3.2%和1.8%出现了口鼻部异常。产毒素多杀性巴氏杆菌的分离与猪群中出现临床感染猪显著相关（p<0.0001）。从SA猪场购买至少5头猪与产毒素多杀性巴氏杆菌分离风险升高相关（p<0.05）。
