Resumo: | ABSTRACT: A 4-year-old cow with a history of breathing difficulty, progressive weight loss, and muffled heart sound was treated for a period of two weeks, but died and underwent necropsy examination. Macroscopic examination revealed heart with vegetative proliferative lesion firmly adhered to pulmonary valve, lungs with marked consolidation, and the presence of thrombus in vessels. There were grade II ulcers in abomasal mucosa associated to blood clots. Microscopic examination revealed marked thickening of the pulmonary valve due to the proliferation of fibrous connective tissue, inflammatory neutrophil infiltration, fibrin deposition, and a significant number of coccoid basophilic bacteria. Septic thromboemboli were present in the large and small pulmonary blood vessels suggestive of embolic pneumonia. The bacterial culture of the valve showed growth of small, nonhemolytic colonies that demonstrated satellitism to coagulase-negative staphylococci contaminating colonies, which were subjected to 16S gene sequencing and were compatible with Helcococcus ovis in GenBank. This was the first report of H. ovis endocarditis in cattle in South America. |
