title: Intra-abdominal botryomycosis in a dog.
abstract: A 6-year-old 41.8-kg (92-lb) sexually intact male German Shepherd Dog used as an attack and pursuit dog by the local police department was examined because of general malaise and sudden onset of ataxia. Abnormal findings included a high WBC count, fever, and ongoing weight loss. Physical examination was unrevealing initially, in part because of the aggressive nature of the dog. Following treatment with antibiotics, an abdominal mass was detected during a second physical examination, and was confirmed radiographically. Subsequent ultrasound examination revealed a walled mass of mixed echogenicity, with areas of detectable fluid movement. A laparotomy was performed to remove the mass, which weighed 2.2 kg (4.5 lb). Histologic findings were consistent with botryomycosis, and Staphylococcus intermedius was isolated on bacteriologic culture. Postoperative treatment consisted of intravenous, intra-abdominal, and oral administration of antibiotics. Diagnosis of botryomycosis requires histologic examination and bacteriologic culture of the lesion. Treatment consists of surgical intervention and administration of antimicrobials. Botryomycosis is a poorly understood and rarely reported disease found in many species. A computer search of the literature failed to reveal any previous reports of intra-abdominal botryomycosis in dogs.
