Mycobacterium tuberculosis
Mycobacteriology and Aerobic ActinomycetesHeat Inactivation Renders Sputum Safe and Preserves Mycobacterium tuberculosis RNA for Downstream Molecular TestsThe World Health Organization End Tuberculosis (TB) strategy has called for the development of—and increased access to—effective tools for diagnosis and treatment of TB disease. Mycobacterium tuberculosis , the causative agent of TB, is categorized as a highly infectious agent.
MinireviewToward the Development of a Circulating Free DNA-Based In Vitro Diagnostic Test for Infectious Diseases: a Review of Evidence for TuberculosisThe detection of circulating free DNA (cfDNA) has transformed the field of oncology and prenatal diagnostics. Clinical application of cfDNA for disease diagnosis and monitoring, however, is relatively recent in the field of infectious disease.
Mycobacteriology and Aerobic ActinomycetesImpact of External Quality Assurance on the Quality of Xpert MTB/RIF Testing in Viet NamFollowing the endorsement of the Xpert MTB/RIF assay (Cepheid, Sunnyvale, CA, USA) by the World Health Organization (WHO) in 2010, Viet Nam’s National Tuberculosis Control Program (NTP) began using GeneXpert instruments in NTP laboratories. In 2013, Viet Nam’s NTP implemented an Xpert MTB/RIF external quality assurance (EQA) program in collaboration with the U.S.
Mycobacteriology and Aerobic ActinomycetesAdded Value of Xpert MTB/RIF Ultra for Diagnosis of Pulmonary Tuberculosis in a Low-Prevalence SettingXpert MTB/RIF (Xpert) for direct molecular detection of Mycobacterium tuberculosis and rifampin resistance from clinical specimens has dramatically improved the diagnosis of tuberculosis (TB). Xpert MTB/RIF Ultra (Ultra) is proposed as a substitute of Xpert with increased sensitivity and improved rifampin resistance detection.
Mycobacteriology and Aerobic ActinomycetesGenetic Diversity of Multi- and Extensively Drug-Resistant Mycobacterium tuberculosis Isolates in the Capital of Iran, Revealed by Whole-Genome SequencingThe emergence and spread of multidrug resistant (MDR) Mycobacterium tuberculosis complex (MTBC) strains is a critical global health problem. Between 2014 and 2018, 606 MTBC strains were isolated from 13,892 suspected pulmonary tuberculosis (TB) patients in Tehran, Iran, including 16 (2.6%) MDR-TB cases.
Mycobacteriology and Aerobic ActinomycetesIdentifying Mixed Mycobacterium tuberculosis Infection and Laboratory Cross-Contamination during Mycobacterial Sequencing ProgramsThe detection of laboratory cross-contamination and mixed tuberculosis infections is an important goal of clinical mycobacteriology laboratories. The objective of this study was to develop a method to detect mixtures of different Mycobacterium tuberculosis lineages in laboratories performing mycobacterial next-generation sequencing (NGS).
Mycobacteriology and Aerobic ActinomycetesFISHing Mycobacterium tuberculosis Complex by Use of a rpoB DNA Probe BaitRoutine staining of sputum specimens does not identify acid-fast bacilli as Mycobacterium tuberculosis with utmost precision, limiting its usability as a confirmatory test for pulmonary tuberculosis. We have combined Ziehl-Neelsen staining and fluorescence in situ hybridization (FISH) to detect M...
