Arm. Valim et al., Mutations in the rpoB gene of multidrug-resistant Mycobacterium tuberculosis isolates from Brazil, J CLIN MICR, 38(8), 2000, pp. 3119-3122
Mutations in a 69-bp region of the rpoB gene associated with rifampin resis
tance (Rif) in 100 isolates (82 Rif(T)) from three states of Brazil were st
udied. Twenty-one different kinds of mutations were identified in the Rif(T
) isolates, and six new alleles are described.
