A total ... -
Effect of Linezolid in Combination With Isoniazid and Rifampicin Against Multidrug Resistant Mycobacterium Tuberculosis Clinical Isolates
Coban, Ahmet Yilmaz; Bilgin, Kemal; Uzun, Meltem; Durupinar, Belma (Ankara Microbiology Soc, 2009)Tuberculosis continues to be a serious public health problem worldwide. Since multi-drug resistant strains of Mycobacterium tuberculosis constitutes a serious problem in tuberculosis control, new and more effective ... -
Evaluation of Agar-Based Medium with Sheep Sera for Testing of Drug Susceptibility of Mycobacterium tuberculosis to Isoniazid, Rifampin, Ethambutol, and Streptomycin
Coban, Ahmet Yilmaz; Uzun, Meltem; Bozdogan, Bulent (Amer Soc Microbiology, 2013)The performance of sheep sera instead of sheep blood in agar-based media was investigated for susceptibility testing of Mycobacterium tuberculosis against primary drugs. The levels of agreement between agar-based medium ... -
Evaluation of crystal violet decolorization assay for minimal inhibitory concentration detection of primary antituberculosis drugs against Mycobacterium tuberculosis isolates
Coban, Ahmet Yilmaz; Akbal, Ahmet Ugur; Uzun, Meltem; Cayci, Yeliz Tanriverdi; Birinci, Asuman; Durupinar, Belma (Fundaco Oswaldo Cruz, 2016)In this study we evaluated the crystal violet decolorization assay (CVDA) for detection of minimum inhibitory concentration (MIC) of antituberculosis drugs. 53 isolates were tested in this study and 13 of them were multidrug ... -
