Abstract

Foi realizada uma comparação entre os métodos de microscopia fluorescente e Ziehl-Neelsen, para evidenciação de bacilos álcool-ácido resistentes em secreções pulmonares. A sensibilidade e especificidade de cada método foram avaliadas em função da cultura, mostrando que o método fluorescente apresentou uma diferença de sensibilidade de 7,28% e 3,17% para as áreas estudadas. As diferenças quanto a especificidade foram desprezíveis. Houve uma associação positiva entre ambos os métodos.<br>A comparison between fluorescent microscopy and the Ziehl-Neelsen methods for evidencing resistant acid-fast bacilli in pulmonary secretions was drawn. Sensibility and specificity of each one were evaluated according to the results of the sputum culture examination. The fluorescent method showed a variety in sensibility of 7.28% and 3.17% in the studied areas. The differences in specificity were insignificant. There was a positive association between the two methods
