Clostridial infections in goats have been associated frequently with enteric diseases or gas gangrene but very rarely with the reproductive system. We describe here 12 cases of fatal postpartum gangrenous metritis in does associated with infection by several clostridial species. Clinically, these cases were characterized by rapid onset of hyperthermia followed by death after kidding. On postmortem examination, the uteri appeared to be necrotic and were hemorrhagic and edematous. Microscopically, the uteri had diffuse coagulative necrosis, edema, hemorrhage, and fibrinous thrombi with intralesional gram-positive rods. was isolated from 7 of 9 uterine samples cultured, and , , , or were demonstrated by immunohistochemistry (IHC) in the 5 cases examined. IHC for was negative in all 5 cases. PCR performed on 3 of the isolates was positive for alpha toxin and perfringolysin, identifying these isolates as type A. Clostridial infection should be considered in cases of postpartum gangrenous metritis of does.
山羊梭菌感染常与肠病或气性坏疽有关,但很少与生殖系统有关。我们在此描述了 12 例与多种梭菌感染相关的产后坏死性子宫炎母羊致死病例。临床上,这些病例的特征是产后迅速发热,随后死亡。尸检时,子宫呈坏死性,出血和水肿。显微镜下,子宫弥漫性凝固性坏死、水肿、出血和有纤维蛋白血栓形成,伴有腔内革兰氏阳性杆菌。从 9 个子宫样本中培养的 7 个样本中分离出 ,在 5 个检查的病例中通过免疫组织化学(IHC)显示 、 、 、 或 。在所有 5 个病例中, 免疫组织化学均为阴性。对 3 个分离株进行的 PCR 检测为α毒素和产气荚膜梭菌毒素阳性,鉴定这些分离株为 A 型。产后坏死性子宫炎母羊应考虑梭菌感染。
