Abstract excerpt
We have investigated the effect of genetic alterations in the rpsL gene on the MICs of streptomycin for Mycobacterium tuberculosis strains. Direct DNA sequencing showed a point mutation in 23/121 strains; in 18 strains the mutation was associated with an amino acid change. The MICs of streptomycin in 22 out of 23 point-mutated strains were > or = 256 mg/L. Restriction fragment length polymorphism (RFLP) analysis...
