The necropsy records of dairy cows with mastitis were reviewed from the provincial veterinary laboratory in Guelph (44 cases of mastitis in nine years) and from the Ontario Veterinary College (168 cases in 14 years). Mastitis was considered to be the primary cause of death in 167 of 212 cows (79%). Of these 167 cases of mastitis, Escherichia coli was involved in 107 (64%), Klebsiella sp. in 12 (7%) and Staphylococcus aureus in 11 (7%). Bacteriology was not reported in 22 cases. Coliform mastitis, the most commonly identified type of fatal mastitis, was characterized histologically by the presence of infarcted areas in affected glands and by the lack of demonstrable bacteria, and was thus easily identified from fatal mastitis caused by S. aureus.

对来自圭尔夫省兽医实验室（九年中有44例乳腺炎病例）和安大略兽医学院（十四年中有168例病例）的患乳腺炎奶牛的尸检记录进行了回顾。在212头奶牛中，167头（79%）的乳腺炎被认为是主要死因。在这167例乳腺炎病例中，大肠杆菌感染107例（64%），克雷伯菌属感染12例（7%），金黄色葡萄球菌感染11例（7%）。22例未报告细菌学检查结果。大肠菌性乳腺炎是最常见的致命性乳腺炎类型，其组织学特征为受影响腺体出现梗死区域且未发现明显细菌，因此很容易与金黄色葡萄球菌引起的致命性乳腺炎区分开来。
