OBJECTIVE: To evaluate preventive measures recommended during patient care for respiratory symptoms, with pulmonary tuberculosis. METHODS: Exploratory-descriptive study, retrospective, developed from information collected in medical records of patients with respiratory symptoms, diagnosed with pulmonary tuberculosis. RESULTS: The number of tuberculosis cases in the city diagnosed during hospitalization during the study period was 65,29 (44.6%). As for the biosecurity measures during the hospitalization of 29 diagnosed cases, early aerosol were found in medical records in 13 (44.8%) patients. CONCLUSION: Data show that nursing professionals, working in hospitals, still exposed to risks of latent infection.

OBJETIVO: Avaliar as medidas preventivas recomendadas durante a assistência aos pacientes sintomáticos respiratórios, com tuberculose pulmonar. MÉTODOS: Estudo exploratório-descritivo, retrospectivo, desenvolvido a partir deinformações coletadasnos arquivosde pacientes sintomáticos respiratórios, com diagnóstico de saída tuberculose pulmonar. RESULTADOS: O número de casos de tuberculose no município durante o período do estudo foi de 65, 29 (44,6%) destes casos foram diagnosticados durante a internação. Quanto as medidas de biossegurança, durante a admissão dos 29 casos diagnosticados, foram encontrados registros de precaução por aerossóis nos prontuários de 13 (44,8%) pacientes. CONCLUSÃO: Os dados mostram que os profissionaisde enfermagem, que trabalham nos hospitais, continuam expostos aorisco de infecção latente.

Indirect drug susceptibility tests of Mycobacterium tuberculosis was done to investigate the accuracy and feasibility of a broth microdilution method (BMM) for determining minimal inhibitory concentrations of conventional drugs against M. tuberculosis. Test drugs included isoniazid (H), rifampicin (R), ethambutol (E), streptomycin (S) and pyrazinamide (Z). Fifty isolates of M. tuberculosis from patients who had never received drug therapy, and H37Rv strain for control, were evaluated in the system. When comparing this method with the gold standard proportional method in Lowenstein-Jensen medium, sensitivity of 100% for all drugs and specifities of 91, 100, 96, 98 and 85% were observed respectively for H, R, E, S and Z. The BMM was read faster (14-20 days) than the proportional method (20-28 days). The microdilution method evaluated allows the testing of multiple drugs in multiple concentrations. It is easy to perform and does not require special equipment or expensive supplies. In contrast to radiometric method it does not use radioactive material.
