Published: November 2004

Genetic analysis of the embB gene revealed mutations in 17 (68%) of 25 ethambutol (EMB) resistant isolates (M306I, M306V, M306L, Q497R) but also in 4 (20%) of 20 EMB-susceptible isolates of Mycobacterium tuberculosis, namely, an ATG-->ATM substitution resulting in M306I, G406N, and the novel alterations M423I and A659T.

Whole genome sequencing (WGS) is sensitive tool for the analysis of tuberculosis transmission and drug-resistance. We used WGS to analyze the evolution from isoniazid monoresistance to MDR/preXDR during a prolonged household outbreak. The outbreak started with a isoniazid resistant strain (katG S315T mutation) and evolve in two cases to pre-XDR phenotype (with mutations in katG, rpoB, embB, pncA and gyrA genes).

Article Synopsis
  • The study investigated the genomics of zoonotic human tuberculosis caused by Mycobacterium bovis (M. bovis), focusing on virulence and drug resistance using whole-genome sequencing (WGS).
  • Five strains of M. bovis were isolated from patients, all belonging to the same spoligotype and showing resistance to multiple antibiotics, indicating significant drug resistance.
  • Phylogenetic analysis demonstrated genetic ties between the sequenced strains and previously identified strains from cows and humans in different countries, suggesting interconnectedness in the spread of the bacteria.

The rising prevalence of drug-resistant Mycobacterium tuberculosis (MTB) strains poses a significant challenge to global tuberculosis (TB) control efforts. This study aimed to analyze drug resistance patterns and investigate the molecular characteristics of 193 MTB clinical isolates to shed light on the mechanisms of drug resistance. Of the 193 MTB clinical isolates, 28.

Background: Tuberculosis (TB), mainly caused by (), remains a serious public health problem. Increasing evidence supports that selective evolution is an important force affecting genomic determinants of phenotypes. It is necessary to further understand the selective evolution and identify the positively selected genes that probably drive the phenotype of .
