| الوصف: | Bacillus cereus is a Gram-positive bacterium commonly reported in soils and plants that occupy various ecological habitats, and the main source of contamination for cattle is silage. This report described a case of fetal loss associated with B. cereus infection in a cow. An 8-month-old, Nelore female bovine fetus from a beef farm was submitted for necropsy. A gross examination revealed fibrinous pleuropneumonia and fibrin exudation on the liver surface. The morphological diagnosis was restricted to the lungs and liver. In the lungs there was fibrinosuppurative pleuropneumonia associated with numerous aggregates of rod-shaped bacteria. In the liver there was moderate focally extensive fibrinous peri hepatitis.The lungs, liver, thoracic, and abomasal fluid cultures yielded pure cultures of B. cereus, indicating that these bacteria should be recognized as a cause of bovine abortion in fetuses that macroscopically present fibrin in the abdominal and thoracic cavity. RESUMO: Bacillus cereus é uma bactéria Gram-positiva, comumente encontrada em solos e plantas que ocupam diversos habitats ecológicos sendo a silagem a principal fonte de contaminação para bovinos. Este relato descreve um caso de perda fetal associada à infecção por B. cereus em uma vaca. Um feto bovino fêmea da raça Nelore, de oito meses de idade, procedente de uma fazenda de corte, foi submetido à necropsia. Ao exame macroscópico observou-se pleuropneumonia fibrinosa e exsudação de fibrina na superfície do fígado. Histologicamente, as lesões estavam restritas aos pulmões e fígado. Nos pulmões havia pleuropneumonia fibrinosupurativa associado a numerosos agregados de bactérias em forma de bastonete. No fígado haviaperi hepatitefibrinosa focalmente extensa moderada. As culturas de pulmão, fígado, líquido torácico e abomasal produziram cultura pura de B. cereus indicando que esta bactéria deve ser reconhecida como causa de aborto bovino em fetos que apresentem macroscopicamente fibrina nas cavidades abdominal e torácica. |
