A 2-year-old DNA-sexed female Congo African grey parrot (Psittacus erithacus erithacus) was evaluated for self-trauma of the feathers and skin of the tail base for a duration of more than 1 year. All rectrices and tail coverts were missing, the skin of the tail base was thickened and ulcerated, and the uropygial gland was swollen. Results of a complete blood cell count revealed relative monocytosis and basophilia. Survey radiographs showed truncation and lysis of the caudal vertebrae and pygostyle. Results of biopsy and bacterial culture of the tail base lesions revealed an ulcerative bacterial dermatitis positive for staphylococcal cassette chromosome mec (SCCmec) type IV (community-acquired) methicillin-resistant Staphylococcus aureus (MRSA). The bird was treated with oral trimethoprim-sulfamethoxazole, meloxicam, fluoxetine, topical lidocaine gel, and hydrotherapy. One month later, tail feather regrowth was evident; however, follow-up over 2 years found continued self-trauma to the rectrices in spite of repeated skin biopsies negative for MRSA or other bacteria. It is unknown if the MRSA cultured from this bird was commensal or acquired from either the environment or humans to which the bird was exposed.
一只2岁经DNA鉴定为雌性的刚果非洲灰鹦鹉（Psittacus erithacus erithacus）因尾基部羽毛和皮肤自我损伤超过1年接受评估。所有尾羽和尾覆羽均缺失，尾基部皮肤增厚并溃疡，尾脂腺肿大。全血细胞计数结果显示相对单核细胞增多和嗜碱性粒细胞增多。X线平片显示尾椎和尾综骨截断和溶解。尾基部病变的活检和细菌培养结果显示为溃疡性细菌性皮炎，对IV型葡萄球菌盒式染色体mec（SCCmec）（社区获得性）耐甲氧西林金黄色葡萄球菌（MRSA）呈阳性。这只鸟接受了口服甲氧苄啶-磺胺甲恶唑、美洛昔康、氟西汀、外用利多卡因凝胶和水疗治疗。1个月后，尾羽明显重新生长；然而，2年的随访发现，尽管多次皮肤活检对MRSA或其他细菌呈阴性，但尾羽仍持续出现自我损伤。尚不清楚从这只鸟身上培养出的MRSA是共生菌，还是从鸟接触的环境或人类身上获得的。
