| Popis: | 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. |
