Abstract:
The Genotype MTBDR assay was tested for its capability to detect rifampicin (RMP) and isoniazid (INH) resistance (r) and susceptibility (s) directly from 42 smear-positive sputum specimens (15 RMPr/INHr, 2 RMPs/INHr and 25 RMPs/INHs Mycobacterium tuberculosis complex strains). The concordance between the MTBDR assay and conventional drug susceptibility testing was 100%.

Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
