A survey was undertaken of the occurrence, serotype, antimicrobial sensitivity and plasmid content of members of the tribe Proteeae in the environment of two calf-rearing units in the county of Avon in South West England. Examples of the following species were found: Proteus mirabilis, Prot. vulgaris, Prot. vulgaris Biogroup 2, Morganella morganii, Providencia stuartii, Prov. alcalifaciens and Prov. rettgeri. A wide range of serotypes was found, many having been previously reported from nosocomial isolates. A total of 15% of isolates carried plasmids; six pairs of isolates were identified which had identical serotypes but different patterns of plasmid carriage. The antimicrobial sensitivity of the isolates was generally similar to isolates of Proteeae from humans. Although no truly aminoglycoside-resistant isolates were found, some isolates of Prov. stuartii and Prov. rettgeri had MIC's higher than the other isolates to gentamicin and netilmicin, suggesting the presence of low levels of the enzyme AAC 2'. The study demonstrates that there is a considerable diversity of species and types of Proteeae associated with calves and their environment. It seems likely that a potential cause of colonization of the human gut by Proteeae is the consumption of meat.
对英格兰西南部埃文郡两个犊牛饲养场环境中变形杆菌族成员的发生情况、血清型、抗菌敏感性和质粒含量进行了一项调查。发现了以下物种的实例：奇异变形杆菌、普通变形杆菌、普通变形杆菌生物群2、摩根摩根菌、斯氏普罗威登斯菌、产碱普罗威登斯菌和雷氏普罗威登斯菌。发现了广泛的血清型，其中许多先前已从医院分离株中报道过。总共15%的分离株携带质粒；鉴定出六对分离株，它们具有相同的血清型但质粒携带模式不同。这些分离株的抗菌敏感性通常与来自人类的变形杆菌族分离株相似。虽然没有发现真正耐氨基糖苷类的分离株，但一些斯氏普罗威登斯菌和雷氏普罗威登斯菌分离株对庆大霉素和奈替米星的最低抑菌浓度高于其他分离株，表明存在低水平的AAC 2'酶。该研究表明，与犊牛及其环境相关的变形杆菌族的物种和类型存在相当大的多样性。变形杆菌在人类肠道定植的一个潜在原因似乎是食用肉类。
