Uterine pathology in buffaloes: A pathomorphological study

In present study, 375 uteri of non-descript and graded murrah buffaloes aged 4–10 years with no breeding history were collected from the slaughterhouses in and around Hyderabad. Gross, histopathological and electron microscopic studies were carried out. The distribution of the lesions into acute, sub-acute, chronic and chronic suppurative endometritis was 11.20, 6.10, 18.10 and 3.20 per cent, respectively. Microscopically, acute endometritis was characterized by severe congestion of blood vessels, enlargement of stromal cells, denudation of surface epithelium and mild to moderate infiltration of polymorphs and lymphocytes in stratum compactum. Severity of some of the lesions observed in acute endometritis was increased in sub acute and chronic endometritis. Dilatation of endometrial glands and necrosis of glandular epithelium in chronic suppurative endometritis cases was recorded. Confirmed chronic endometritis tissues subjected to scanning electron microscopy revealed thickening of endometrium, presence of fibrous tissue and lack of microvilli with complete destruction of glandular structures at few places.
