SPONDYLITIS CAUSED BY BRUCELLA-ABORTUS

A case of severe chronic spondylitis of the lumbar spine caused by Brucella abortus is presented. Infection was probably associated with ingestion of raw cow's milk. A technetium bone scan provided evidence of activity as early as two years before the radiographic abnormalities were evident. Although rarely seen in brucellosis, a large left psoas abscess formed. After extensive resection and debridement of all necrotic tissue, along with prolonged use of oral doxycycline, the patient recovered completely. The clinical, laboratory, therapeutic, and pathogenic aspects of Brucella spondylitis are discussed. © 1979 Southern Medical Association.
