Development of rifapentine susceptibility tests for Mycobacterium tuberculosis.

abstract：:TEM- and SHV-type extended-spectrum beta-lactamases (ESBLs) are the most common ESBLs found in the United States and are prevalent throughout the world. Amino acid substitutions at a number of positions in TEM-1 lead to the ESBL phenotype, although substitutions at residues 104 (E to K), 164 (R to S or H), 238 (G to S...
