WebA limitation of our study is that phenotypic pyrazin-amide susceptibility testing was not performed on the se-quenced isolates. Nonetheless, correlation with phenotypic testing has been previously reported in the literature for most polymorphisms, enabling us to estimate the propor-tion likely to be pyrazinamide resistant (10–15). In addition, WebA phenotypic assay provides a direct measure of drug resistance and is analogous to antibiotic-susceptibility testing of bacteria. The currently available phenotypic assays use recombinant DNA methods to measure the ability of a …
