Postpartum metritis and septicemia in an adult cross-breed pig: Aetiopathology and antibiotic sensitivity pattern

The adult cross-breed pig had a history of retention of placenta after farrowing and discharge of purulent materials from vagina. At necropsy, epicardial hemorrhage, hemorrhagic lymph nodes, congestion of visceral organs, gastric and caecal mucosa were observed. The uterus was thickened, highly congested and hemorrhagic with presence of necrotic materials in the endometrium. Microscopically, vascular changes in different organs, fibrin thrombi in lymph node, multiple follicular cysts in ovary, severe vascular and inflammatory changes in endometrium and myometrium, meningitis, leucocyte margination and perivascular edemas in brain were observed. Escherichia coli was isolated from heart blood. The isolate was sensitive to ofloxacin, ciprofloxacin, chloramphenicol, levofloxacin, meropenem, ceftriaxone, amikacin, oripenem, ceftazidime/clavulanate. Based on pathology and bacteriology, the case was diagnosed as post-partum metritis and septicemia associated with E. coli.
