Laboratory-acquired brucellosis: a Spanish national survey.
A retrospective postal survey was carried out among 1240 clinical microbiology laboratory workers in Spain. Overall, 75 (43 microbiologists and 32 technicians) had suffered from laboratory-acquired brucellosis (LAB). Considering the total number of replies (N=628), the rate of LAB was 11.9%. The risk of suffering from LAB was clearly related to the number of isolates of Brucella spp. per year. A major break in biosafety measures was recognized in 60 cases (80%). In nine cases, processing was considered to be secure, and in six cases, the source of infection was unknown. Diagnosis was based on serology in all cases. In 51 cases (68%), blood cultures confirmed diagnosis. A variety of regimens were used to treat the 75 LAB cases. The combination of tetracycline and streptomycin was the most commonly used regimen (in 35 patients), followed by the combination of tetracycline and rifampicin (in 19 cases). Only 10 patients (13.3%) suffered from complications. No differences in resolution were observed according to the antimicrobial regimen. Microbiological laboratory workers are still at risk of developing LAB. Improvements in safety seem to be the best means of
