Increasing resistance of M. tuberculosis to anti-TB drugs in Saudi Arabia.
The incidence of drug resistance in Mycobacterium tuberculosis (MTB) isolated from our hospital between April 1996 and March 1998 was compared with an earlier study (1993-1995). Thirty (29.7%) of 101 MTB isolates were resistant to one or more anti-TB drugs and 21 (20%) of 101 were multi-drug resistant M. tuberculosis (MDR-TB). ⋯ Resistance to pyrazinamide and ethambutol was 7.9 and 6.9%, respectively. There was a three-fold increase in resistance compared with the earlier study.
