“…Bronchitis and/or lymphoid hyperplasia of the bronchus-associated lymphoid tissue can be observed histologically with Mycoplasma spp infection in poultry and would have provided corroborating evidence of a mycoplasmal infection. 6,25,28 The presence of Mycoplasma spp in the respiratory system was investigated by culture and mycoplasma PCR in vulture Nos. 2 and 3.…”

Mycoplasma Corogypsi–Associated Polyarthritis and Tenosynovitis in Black Vultures (Coragyps atratus)

et al. 2012

Three wild American black vultures (Coragyps atratus) were presented to rehabilitation centers with swelling of multiple joints, including elbows, stifles, hocks, and carpal joints, and of the gastrocnemius tendons. Cytological examination of the joint fluid exudate indicated heterophilic arthritis. Radiographic examination in 2 vultures demonstrated periarticular soft tissue swelling in both birds and irregular articular surfaces with subchondral bone erosion in both elbows in 1 bird. Prolonged antibiotic therapy administered in 2 birds did not improve the clinical signs. Necropsy and histological examination demonstrated a chronic lymphoplasmacytic arthritis involving multiple joints and gastrocnemius tenosynovitis. Articular lesions varied in severity and ranged from moderate synovitis and cartilage erosion and fibrillation to severe synovitis, diffuse cartilage ulceration, subchondral bone loss and/or sclerosis, pannus, synovial cysts, and epiphyseal osteomyelitis. No walled bacteria were observed or isolated from the joints. However, mycoplasmas polymerase chain reactions were positive in at least 1 affected joint from each bird. Mycoplasmas were isolated from joints of 1 vulture that did not receive antibiotic therapy. Sequencing of 16S rRNA gene amplicons from joint samples and the mycoplasma isolate identified Mycoplasma corogypsi in 2 vultures and was suggestive in the third vulture. Mycoplasma corogypsi identification was confirmed by sequencing the 16S-23S intergenic spacer region of mycoplasma isolates. This report provides further evidence that M. corogypsi is a likely cause of arthritis and tenosynovitis in American black vultures. Cases of arthritis and tenosynovitis in New World vultures should be investigated for presence of Mycoplasma spp, especially M. corogypsi.

“…28 In avian species, Mycoplasma spp–induced arthritis and tenosynovitis are well documented in galliformes where infection with Mycoplasma synoviae or, less commonly, Mycoplasma gallisepticum causes articular and tendon lesions in chickens and turkeys, affecting infected populations with increased morbidity and mortality. 28 …”
