Primarydrug-resistance of Mycobacterium tuberculosis in Shanghai, 1985

OBJECTIVE: To evaluate the problem of antituberculosis drug resistance in Shanghai, 1985-1995. METHOD: All of the strains of M. tuberculosis from new patients with pulmonary tuberculosis were tested for resistance to INH, RFP, EMB, SM, PAS, and KM by the absolute concentration method on Lowenstein-Jensen medium. RESULTS: The rates of primary drug resistance to SM, INH, RFP, PAS, and KM were 10.2%, 5.2%, 4.8%, 5.6%, and 3.9% respectively in 1985, and decreased to 4.8%, 4.8%, 4.3%, 3.6%, and 2.6% in 1995, while the rate of drug resistance to EMB was 1.3% in 1985, and increased to 3.3% in 1995. The primary resistance rate to one or more drugs was 15.6% in 1985 and 8.2% in 1995. The resistance rates to one, two, three, four, five, and six drugs were 5.9%, 4.6%, 2.5%, 1.5%, 0.4%, and 0.8% respectively in 1985, and decreased to 1.9%, 3.5%, 1.2%, 1.2%, 0.1%, and 0.4% in 1995. The resistance rates to INH and RFP were 1.9% in 1992-1993, 2.4% in 1994-1995. CONCLUSION: The primary drug resistance of M. tuberculosis in Shanghai, 1985-1995, was in a trend of decline, but multi-drug resistance is still seriously existed.
