| مستخلص: |
A 31-month-old Holstein dairy cow aborted at 224 days of gestation with ejection of cheese-like lochia. Citrobacter koseri, which commonly exists in the normal flora of human and animal digestive tracts, was isolated from aborted fetal tissues (liver, spleen, kidney, heart, lung, cerebrum, and skeletal muscle) and fetal membranes. Histopathological examination revealed suppurative fibrinous meningoencephalitis of the cerebrum, cerebellum, and brainstem; suppurative bronchopneumonia; suppurative chorioamnionitis; and fibrous splenic serositis. Numerous gramnegative bacilli were detected in the cytoplasm of macrophages and/or neutrophils in these lesions. Bacteriological investigation and immunohistochemical staining identified the bacilli as C. koseri. This is the first report of cattle abortion caused by C. koseri infection in dairy cattle.
