Aim. To evaluate the epidemiological and clinical features, therapeutic regimen, complications and outcome of human brucellosis in Bulgaria over the last 3 years.Methods. The study was carried out between August 2007 and December 2009. Fifty-five cases were included in this retrospective study. The diagnosis was based on clinical manifestations compatible with brucellosis and/or serological evidence of Brucella infection.Results. Fifty-five cases were evaluated. The main route of transmission was the consumption of unpasteurized milk and fresh goat and sheep cheese. The infection was introduced in Haskovo region, bordering on Greece and Turkey, by illegally imported animals. Asymptomatic infection predominated and only 10 patients were with symptomatic brucellosis: acute in 4 and subacute in 6 of the patients. Focal involvement was present in 3 patients.Conclusion. Although the diagnosis was delayed a multidisciplinary approach involving measures pointed to both humans and animals helped control the infection in 2009. Physicians in nonendemic countries such as Bulgaria should be aware of the fact that brucellosis is a possible cause of fever of unknown origin with a history of animal contact.
