We present a statistical summary of results from the Model Performance Evaluation Program (MPEP) for Mycobacterium tuberculosis Drug Susceptibility Testing, 1994 to 2008, implemented by the U.S. Centers for Disease Control and Prevention (CDC). During that period, a total of 57,733 test results for culture isolates were reported by 216 participating laboratories for the first-line antituberculo...

The Cobas TaqMan MTB test, based on real-time PCR technology, was evaluated for direct detection of Mycobacterium tuberculosis complex (MTBC) in respiratory specimens. A total of 1,093 samples from 446 patients, including 118 acid-fast smear-positive and 975 acid-fast smear-negative specimens, were investigated. Diagnostic cultures performed with 7H11 agar, Löwenstein-Jensen medium, and the Bac...

Objective: In the study, 419 Mycobacterium tuberculosis complex strains (MTC), which were isolated from samples sent to Regional Tuberculosis Laboratory in our city between 2015 and 2019 with suspected Erzurum surrounding cities investigated. Methods: Our research is a retrospective cross-sectional study clinical Public Health suspicion of within five-year period January December first evaluate...

We noted with interest the paper by Forgacs et al. (2) reporting on a case of tuberculosis with an apparent response to treatment with trimethoprim-sulfamethoxazole (TMP-SMX) and the subsequent in vitro studies indicating that the majority of Mycobacterium tuberculosis strains may be susceptible to TMP-SMX. As the Forgacs paper implied that it is the sulfonamide component of TMP-SMX that has an...

BACKGROUND Molecular resistance testing fails to explain all fluoroquinolone resistance, with a continued need for a suitable rapid phenotypic drug susceptibility testing method. OBJECTIVE To evaluate the optimal method for phenotypic fluoroquinolone susceptibility testing. METHODS Using Löwenstein-Jensen medium, Middlebrook 7H11 agar, BACTEC-MGIT 960 and the resazurin microtitre plate assa...
