LEO H, Elena et al. Determinacion de la susceptibilidad de Mycobacterium tuberculosis a la pirazinamida mediante la prueba de la  pirazinamidasa,: Perú - 1999. Rev. perú. med. exp. salud publica [online]. 2003, vol.20, n.2, pp.105-106. ISSN 1726-4634.

The pyrazinamidase test was used to determine susceptibility to pyrazinamide in 1217 Mycobacterium tuberculosis strains from different areas in Peru received in the National Reference Laboratory of the Instituto Nacional de Salud (Lima, Perú) from March to December 1999. In Vitro susceptibility to pyrazinamidase was determined using Wayne´s method. Primary and acquired resistance to pyrazinamidase rates were 1,9% y 10,5%, respectively.
