一头成年棕色瑞士牛因产后唐纳牛综合症被送往蒙特利尔大学兽医中心医院的大型动物医院。该动物四肢均出现严重全身肿胀，并处于休克状态，表现为低血压、脱水、体温过低、精神状态改变和血液参数异常。它迅速死亡，尸检显示其患有由停乳链球菌亚种引起的全身性严重蜂窝织炎。停乳、支气管肺炎和肾脏弥散性血管内凝血 (DIC) 病变。由于没有皮肤外伤或乳腺炎病史，未发现细菌进入皮下组织的入口。大量侵入性链球菌的纯粹生长与低血压、凝血病和肾功能衰竭相关，支持牛的链球菌中毒性休克样综合征。
An adult Brown Swiss cow was presented to the Large Animal Hospital of the Centre Hospitalier Universitaire Veterinaire de I'Universite de Montreal due to a postpartum downer cow syndrome. The animal had severe and generalized swelling of all 4 limbs and was in shock, as demonstrated by hypotension, dehydration, hypothermia, altered mental status, and abnormal blood parameters. It died rapidly, and necropsy revealed a generalized, severe cellulitis caused by Streptococcus dysgalactiae subsp. dysgalactiae, bronchopneumonia, and lesions of disseminated intravascular coagulation (DIC) in the kidneys. The portal of entry of the bacteria in the subcutaneous tissue was not found, as there was no history of skin trauma or mastitis. The pure growth of large quantities of an invasive Streptococcus species, associated with hypotension, coagulopathy, and renal failure, are supportive of streptococcal toxic shock-like syndrome in a bovine.
