This report summarized the findings of a case of Erysipelothrix rhusiopathiae infection in a farmed Norwegian Red heifer located in the south-east of Norway. The 2.5-year-old pregnant heifer was found dead after a short episode of inappetence. On gross exam, the heifer was severely dehydrated with uterine torsion. Microscopically, necrosis of the endometrium was present throughout the uterus along with presence of intralesional Gram-positive bacteria, interstitial nephritis, and pyelonephritis. E. rhusiopathiae was isolated from the uterus and placenta and was also demonstrated by immunohistochemistry (IHC) in the uterus, placenta, and kidney. The E. rhusiopathiae isolate was further characterized as serotype 5. To the authors' knowledge, this is the first report of bacterial metritis associated with E. rhusiopathiae serotype 5 infection. The etiology of the infection is unknown but the E. rhusiopathiae could have been a primary or opportunistic pathogen. Serotype 5 of E. rhusiopathiae has been identified in several mammalian species in recent years and could be emerging.
本报告总结了挪威东南部一头养殖的挪威红牛小母牛感染豕红斑丹毒丝菌的病例结果。这头2.5岁的怀孕小母牛在出现短暂食欲不振后被发现死亡。大体检查发现，该小母牛严重脱水并伴有子宫扭转。显微镜检查显示，整个子宫的子宫内膜均有坏死，同时存在病灶内革兰氏阳性菌、间质性肾炎和肾盂肾炎。从子宫和胎盘中分离出了豕红斑丹毒丝菌，免疫组织化学（IHC）也在子宫、胎盘和肾脏中证实了该菌的存在。分离出的豕红斑丹毒丝菌进一步被鉴定为血清型5。据作者所知，这是首例与豕红斑丹毒丝菌血清型5感染相关的细菌性子宫炎报告。感染的病因尚不清楚，但豕红斑丹毒丝菌可能是原发性或机会性病原体。近年来，在几种哺乳动物物种中都发现了豕红斑丹毒丝菌血清型5，它可能正在出现。
