Article Synopsis
  • - The study evaluated the participation of public health laboratories (PHLs) in a tuberculosis external quality assessment (EQA) program over three years (2018-2020), managed by the National Tuberculosis Reference Laboratory (NTRL).
  • - Each year, PHLs performed tests on various EQA samples across microscopy, culture, and drug susceptibility testing, with results recorded and analyzed through the Tuberculosis Laboratories Surveillance Network (TULSA).
  • - Results showed fluctuating participation numbers and noteworthy performance statistics, indicating that engaging in EQA positively impacts the accuracy and reliability of tuberculosis testing methods in laboratories.

The incidence of human tuberculosis (TB) disease due to Mycobacterium caprae, an etiologic agent of zoonotic TB along with Mycobacterium bovis, is very low. There are no guidelines for human TB caused by M. caprae, and treatment protocols for infections caused by this microorganism are based on the recommendations for M.

Resistances to anti-tuberculosis (TB) drugs are related to the mutations in the genome of the complex (MTBC). To expose the genomic mutations that cause anti-TB drug resistance. The GenoType MTBDRplus and MTBDRsl assays were used to detect genetic mutations.

Streptomycin (STR) and ethambutol (EMB) are important drugs used for the treatment of tuberculosis. There is a need for fast, reliable and inexpensive methods for detecting resistance to these drugs. The aim of this study was to evaluate the performance of the crystal violet decolorization assay (CVDA) for the detection of STR and EMB resistance that is important drugs in tuberculosis treatment.
