AI Article Synopsis

  • * The study compared the effectiveness of the DiversiLab™ system (rep-PCR) with traditional IS6110-RFLP analysis to identify Mycobacterium tuberculosis in 89 clinical isolates from Korea.
  • * The DiversiLab system successfully grouped the isolates into 8 categories, showing quick and reliable results, and is suggested for molecular epidemiological studies of tuberculosis in Korea.

Article Abstract

Tuberculosis remains a severe public health problem worldwide. Presently, genotyping is used for conducting epidemiologic and clinical studies on tuberculosis cases. We evaluated the efficacy of the repetitive sequence-based PCR (rep-PCR)-based DiversiLab™ system (bioMérieux, France) over the IS6110-restriction fragment length polymorphism analysis for detecting Mycobacterium tuberculosis. In all, 89 clinical M. tuberculosis isolates collected nationwide from Korea were used. The DiversiLab system allocated the 89 isolates to 8 groups with 1 unique isolate when a similarity level of 95% was applied. Seventy-six isolates of the Beijing family and 13 isolates of non-Beijing family strains were irregularly distributed regardless of rep-PCR groups. The DiversiLab system generated a rapid, sensitive, and standardized result. It can be used to conduct molecular epidemiologic studies to identify clinical M. tuberculosis isolates in Korea.

Tuberculosis (TB) is historically the world's deadliest infectious disease. New TB drugs that can avoid pre-existing resistance are desperately needed. The β-lactams are the oldest and most widely used class of antibiotics to treat bacterial infections but, for a variety of reasons, they were largely ignored until recently as a potential treatment option for TB.

Objectives: This study aimed to investigate genotypic characteristics and drug resistance profiles of complex (Mtbc) strains isolated from patients with suspected tuberculosis (TB) in Gabon.

Methods: We performed whole genome sequencing of 430 Mtbc strains cultured between 2012 and 2022. Phylogenetic strain classification, genomic resistance prediction, and cluster analysis were also performed.

The growing issue of drug resistance, particularly multidrug-resistant TB (MDR-TB), has exacerbated this problem. The rise of drug resistance TB is a severe global health concern. In Thailand, a persistent community outbreak of primary MDR-TB has been confirmed in the Tha Maka district of Kanchanaburi province, with an increasing prevalence of MDR-TB among newly diagnosed pulmonary tuberculosis cases.

Whole genome sequencing has been used to investigate the genomic diversity of M. tuberculosis in the northern and southern states of India, but information about the eastern part of the country is still limited. Through a sequencing-based strategy, this study seeks to comprehend the diversity and drug resistance pattern in the eastern region.

Mycobacterium tuberculosis (M. tuberculosis) bacteria can cause oxidative stress and the production of inflammatory cytokines, creating an environment that enhances tumour formation, progression and metastasis. Epidemiological studies have found a link between lung cancer and tuberculosis (TB), but the cellular mechanism is still unclear.
