Mutations and insights into the molecular mechanisms of resistance of Mycobacterium tuberculosis to first-line [PDF]

Genetics and Molecular Biology, 2023
Genetically antimicrobial resistance in Mycobacterium tuberculosis is currently one of the most important aspects of tuberculosis, considering that there are emerging resistant strains for almost every known drug used for its treatment.

Prevalence and drivers of false-positive rifampicin-resistant Xpert MTB/RIF results: a prospective observational study in Rwanda

The Lancet Microbe, 2020
Summary: Background: The Xpert MTB/RIF (Xpert) assay is used globally to rapidly diagnose tuberculosis and resistance to rifampicin. We investigated the frequency and predictors of false-positive findings of rifampicin resistance with Xpert. Methods: We

The RNA Polymerase Inhibitor Corallopyronin A Has a Lower Frequency of Resistance Than Rifampicin in Staphylococcus aureus

Antibiotics, 2022
Corallopyronin A (CorA) is active against Gram-positive bacteria and targets the switch region of RNA polymerase. Because of the high frequency of mutation (FoM) leading to rifampicin resistance, we determined the CorA FoM in S.

Rifampicin resistance in tuberculosis outbreak, London, England [PDF]

, 2005
Mycobacterium tuberculosis isolates cultured from 6 patients associated with an isoniazid-resistant M. tuberculosis outbreak acquired rifampicin resistance. The rpoB gene sequence showed that resistance was associated with rare mutations in each isolate.

Low-cost rapid detection of rifampicin resistant tuberculosis using bacteriophage in Kampala, Uganda. [PDF]

, 2007
BACKGROUND: Resistance to anti-tuberculosis drugs is a serious public health problem. Multi-drug resistant tuberculosis (MDR-TB), defined as resistance to at least rifampicin and isoniazid, has been reported in all regions of the world.

Negligible risk of inducing resistance in Mycobacterium tuberculosis with single-dose rifampicin as post-exposure prophylaxis for leprosy [PDF]

, 2016
Post-exposure prophylaxis (PEP) for leprosy is administered as one single dose of rifampicin (SDR) to the contacts of newly diagnosed leprosy patients. SDR reduces the risk of developing leprosy among contacts by around 60 % in the first 2-3 years after ...

Cell membrane components of Brucella melitensis play important roles in the resistance of low-level rifampicin.

PLoS Neglected Tropical Diseases, 2020
Brucella spp. are facultative intracellular pathogens that can persistently colonize host cells and cause the zoonosis- brucellosis. The WHO recommended a treatment for brucellosis that involves a combination of doxycycline, rifampicin, or streptomycin ...
