Elucidating isoniazid resistance using molecular


Regarding INH, all 11 phenotypically susceptible strains were detected as such by pyrosequencing.Nonetheless, in 18 out of 78 phenotypically INH-resistant strains, pyrosequencing did not detect any mutations in the studied regions.These 11 failures corresponded to 5 different specimens.One sample had no results for any of 5 regions analyzed, 2 specimens failed in 2 of the regions (one in 526, respectively).All clinical strains were genotypically characterized with the Geno Type assay.In addition, for 67 of 79 INH- and/or RIF-resistant strains, genotypic characterization by sequencing was also available.

Ninety clinical strains were analyzed by pyrosequencing.These data were not taken into account when calculating sensitivity and specificity values.

    Gentle, pious and scholarly, this new model was the original Yeshiva bocher—a stark contrast to the traditional Roman warrior of the time.
