Enterococcus hirae infections are reported to cause growth depression, encephalomalacia, endocarditis, and septicemia in chickens. This report describes osteomyelitis in the proximal femur of a 3-week-old broiler chicken that also suffered from valvular endocarditis and liver necrosis. Histologically, clusters of gram-positive coccoid bacteria were found in many organs, including bone lesions. In tissues from 5 of 6 examined chickens from the same flock, E hirae was isolated in large numbers. To the authors' knowledge, this is the first report of spontaneous bacterial osteomyelitis where E hirae was cultured from bone and where coccoid bacteria consistent with Enterococcus spp were simultaneously demonstrated within bone lesions.
屎肠球菌感染据报道可引起鸡生长抑制、脑软化、心内膜炎和败血症。本报告描述了一只 3 周龄肉鸡的股骨骨髓炎，该肉鸡还患有瓣膜心内膜炎和肝坏死。组织学检查发现，包括骨病变在内的许多器官中都存在革兰阳性球菌簇。在来自同一鸡群的 6 只鸡中的 5 只的组织中，大量分离出屎肠球菌。据作者所知，这是首例从骨中培养出屎肠球菌并同时在骨病变中发现与肠球菌属一致的球菌的自发性细菌性骨髓炎的报告。
