LOPEZ NOVO, Magaly; ECHEMENDIA FONT, Miguel  e  VALDIVIA ALVAREZ, José A.. Evaluación de la prueba de la pirazinamidasa para la determinación de la susceptibilidad de Mycobacterium tuberculosis a la pirazinamida. Rev Cubana Med Trop [online]. 1999, vol.51, n.1, pp. 53-54. ISSN 1561-3054.

The pyrazinamidase test was used to determine susceptibility to pyrazinamide in 55 strains of Mycobacterium tuberculosis received at the National Laboratory of Reference and Research of Tuberculosis and Mycobacteria of the "Pedro Kourí" Institute of Tropical Medicine during the first semester of 1997. On comparing the results obtained with the method of proportions, it was attained a correlation of 83.6 % of sensivity with 16.4 % of false positives. It was proved that the pyrazinamidase test should not replece the method of proportions.
