Abstract

An outbreak of nosocomial urinary-tract infection was caused by a strain of Proteus rettgeri that fermented lactose overnight and was resistant to all antimicrobial drugs tested. The nonmotile isolates shared an O (somatic) antigen that differed from those of wild-type P. rettgeri. The organisms proved markedly serum-sensitive. In rats, the isolates elicited an acute interstitial nephritis with associated transient bacteriuria. Attempts to transfer the lac(+) trait and drug-resistance markers to recipient strains of Escherichia coli K-12 failed; exposure of the isolates to acridine orange yielded small numbers of non-lactose-fermenting variants which, however, were still as drug-resistant as before. Epidemiological studies failed to uncover the source of this unique strain and appeared to indicate exogenous spread of infection.

摘要

一次医院内尿路感染暴发是由一株雷特格变形杆菌引起的,该菌株能在一夜之间发酵乳糖,并且对所有测试的抗菌药物均耐药。这些无动力分离株共有一种O(菌体)抗原,与野生型雷特格变形杆菌的抗原不同。这些细菌对血清极为敏感。在大鼠中,这些分离株引发了急性间质性肾炎并伴有短暂菌尿。将乳糖发酵阳性(lac(+))性状和耐药标记转移至大肠杆菌K-12受体菌株的尝试失败了;将这些分离株暴露于吖啶橙后产生了少量非乳糖发酵变体,然而,这些变体仍然像之前一样耐药。流行病学研究未能发现这种独特菌株的来源,似乎表明感染是外源性传播。
