Isoniazid-resistant TB and associated factors in Ethiopia

Public Health Action
BACKGROUND: Isoniazid-resistant, rifampicin-susceptible Mycobacterium tuberculosis (Hr-TB) is the most common form of drug-resistant TB (DR-TB). We investigated the prevalence of and risk factors for Hr-TB in Ethiopia.

Probing Host Pathogen Cross-Talk by Transcriptional Profiling of Both Mycobacterium tuberculosis and Infected Human Dendritic Cells and Macrophages.

, 2008
BACKGROUND: Transcriptional profiling using microarrays provides a unique opportunity to decipher host pathogen cross-talk on the global level. Here, for the first time, we have been able to investigate gene expression changes in both Mycobacterium ...

Mycobacterium tuberculosis Beijing genotype. [PDF]

, 2003
Molecular epidemiologic studies of strains of Mycobacterium tuberculosis are currently conducted worldwide. The genetically distinct Beijing family of strains has been associated with large outbreaks of tuberculosis, increased virulence, and multidrug ...

SERS Facemask for Rapid and Portable Sensing Mycobacterium Tuberculosis Antigens for TB Screening

Advanced Science, EarlyView.
Our study introduced an Au─Ag embedded covalent organic framework (U@COF) ‐mediated facemask for sensing TB antigen ESAT‐6/CFP‐10 complex in clinical droplet samples toward TB screening. Practical analysis of clinical samples demonstrated the availability of our facemask, which is capable of identifying the TB subjects (N = 17) from healthy candidates (

Unlocking a Nitrosuccinate Lyase for Decarboxylative Enzymatic Hydronitration

Angewandte Chemie, EarlyView.
The nitrosuccinate lyase CreD catalyzes C–NO2 bond formation using nitrite in water and shows synthetic practicality with high turnover numbers up to 102,000. A combination of protein engineering and computational methods helped to reveal the mechanistic principles that underpin this unique enzymatic activity.

The impact of the coexistence of mycobacterium avium with mycobacterium tuberculosis on the result of GeneXpert and MGIT susceptibility test

Journal of Infection and Public Health, 2020
Rapid tests to diagnose tuberculosis relies on molecular detection of the M. tuberculosis. GeneXpert MTB/RIF test identifies M. tuberculosis and rifampicin resistance. We present a case of simultaneous coinfection with M. tuberculosis and M. avium.

HLA-B*35-restricted CD8(+)-T-cell epitope in Mycobacterium tuberculosis Rv2903c.

, 2002
Few human CD8(+) T-cell epitopes in mycobacterial antigens have been described to date. Here we have identified a novel HLA-B*35-restricted CD8(+) T-cell epitope in Mycobacterium tuberculosis Rv2903c based on a reverse immunogenetics approach.

Bilateral SERS‐Microneedle Patch for Co‐Diagnosis of Diabetes Mellitus and Tuberculosis Comorbidity

Advanced Science, EarlyView.
Our study introduced a U@mP@Au‐mediated bilateral SERS‐microneedle patch for analyzing glucose levels from ISF and sensitively detecting TB biomarkers from sputum, respectively. This integrated dual‐analyte detecting platform can be used for co‐diagnosis of diabetes mellitus (DM) and tuberculosis (TB) comorbidity, which was demonstrated in ex vivo ...

An investigation of the transmission dynamics of M. tuberculosis. [PDF]

We develop an age-structured deterministic model (TBDYN3) of the transmission dynamics of M. tuberculosis in England and Wales since 1900. The model estimates the age-specific risks of developing' primary', 'endogenous' and 'exogenous' disease and ...

CREAT: A CRISPR‐Based Genome Trimming Strategy for Systematic Identification of Dispensable Regions and Rapid Genome Reduction

Advanced Science, EarlyView.
Current genome‐reduction methods work in a trial‐and‐error fashion, constituting a long‐standing bottleneck in the research. We developed CREAT (CRISPR‐based genome trimming with a multi‐homology‐arm template), a CRISPR‐based genetic approach that enables systematically classifying essential versus non‐essential genomic regions and subsequently ...
