Change in prevalence and molecular characteristics of isoniazid-resistant tuberculosis over a 10-year period in China

open access: yesBMC Infectious Diseases, 2019
Background Isoniazid (INH) represents the cornerstone for the treatment of cases infected with Mycobacterium tuberculosis (MTB) strains. Several molecular mechanisms have been shown to be the major causes for INH resistance, while the dynamic change of ...

Drug Resistance in Tuberculosis

open access: yesAnnals of Saudi Medicine, 1990
Resistance to antituberculosis drugs is due to the occurrence of resistant mutants in the bacterial population even before exposure to these drugs. These mutations are chromosomal in origin. Resistance occurs when the bacterial population is large or when drugs are used alone. Potent drugs such as rifampicin, isoniazid and streptomycin are effective in

RNA Helicase DDX21 Controls CD4+ T Cell Proliferation and Promotes Inflammatory Bowel Disease via Translational Control

open access: yesAdvanced Science, EarlyView.
ABSTRACT Inflammatory bowel disease (IBD) is characterized by dysregulated T cell responses. RNA helicases, including DExD‐box helicase 21 (DDX21), are pivotal in RNA metabolism, but their role in T cell‐mediated pathology during IBD remains unclear. Here, we demonstrate that DDX21 expression in CD4+ T cells correlates with cell cycle and translation ...

Performance of stool-based Xpert MTB/RIF assay in the diagnosis of presumptive pulmonary tuberculosis in adults unable to expectorate sputum

open access: yesMicrobiology Spectrum
This study aimed to compare the performance of stool-based Xpert MTB/RIF(Xpert) assay (Cepheid, USA) against that of smear, culture, and Xpert using respiratory tract specimens (RTS) and stool samples in the diagnosis of adult pulmonary tuberculosis (PTB)

Xpert MTB/RIF and GenoType MTBDRplus assays for the rapid diagnosis of bone and joint tuberculosis

open access: yesInternational Journal of Infectious Diseases, 2015
Background: Bone and joint tuberculosis (BJTB) constitutes about 10–20% of the extrapulmonary tuberculosis (EPTB) cases in China. The GenoType MTBDRplus assay (MTBDR) has been endorsed by the World Health Organization (WHO) for the diagnosis of pulmonary

Significant difference in Th1/Th2 paradigm induced by tuberculosis-specific antigens between IGRA-positive and IGRA-negative patients

open access: yesFrontiers in Immunology, 2022
False negative interferon-γ release assay (IGRA) results constitute the major dilemma for the diagnosis of tuberculosis (TB) infections. Herein, we conducted a cohort study to compare the host immunological response to TB-specific antigens between active
