RT Journal Article SR Electronic T1 Brucellosis and Sacroiliitis: A Common Presentation of an Uncommon Pathogen JF The Journal of the American Board of Family Medicine JO J Am Board Fam Med FD American Board of Family Medicine SP 158 OP 161 DO 10.3122/jabfm.2008.02.070170 VO 21 IS 2 A1 James R. Priest A1 Dennis Low A1 Cliff Wang A1 Thomas Bush YR 2008 UL http://www.jabfm.org/content/21/2/158.abstract AB Musculoskeletal problems are the most common chief complaint in ambulatory medicine across all specialties, and back pain is one of the top 10 problems encountered by the general practitioner.1,2 The differential diagnosis of lower back pain is exhaustive, but a history significant for constitutional symptoms or unusual exposures should prompt a work-up for an infectious cause. We describe the case of a 25-year-old man with a Brucella abortus sacroiliitis and possible orchiitis after consumption of unpasteurized cheese imported from El Salvador. The patient was successfully treated with gentamycin, rifampin, and doxycycline. Though the presentations of brucellosis are myriad, osteoarticular involvement of the axial skeleton is the most common presentation of this zoonotic infection.3 In the United States brucellosis is rarely encountered and is typically limited to people who are exposed during travel to endemic areas. Here we review briefly the epidemiology and presentation of a Brucella infection and current recommendations for treatment.
