Introduction. The Mycobacteriology Spanish Working Group (MSWG) has conducted an epidemiological, descriptive and retrospective study to try to know the level of first line drug resistances in Mycobacterium tuberculosis strains in Spain.


Material and methods. Data were obtained from a total of 1083 strains isolated between October and November 2006 in 120 microbiology laboratories from 16 autonomous communities and Melilla.


Results. A primary resistance rate of 8.3% and 4.9% was obtained for isoniazid (INH). The probability of suffering resistant tuberculosis was major in the immigrant population with a resistance rate of 12%. Repeating these surveillance studies in later years is recommended.

Key words: Tuberculosis. Resistance. Antituberculous agents.
