Identification of primary drug resistance to rifampin in Mycobacterium leprae strains from leprosy patients in Amazonas State, Brazil.

چکیده
The aim of this study was to identify polymorphisms in the folp1, gyrA, and rpoB genes in leprosy patients treated in Amazonas State, Brazil. Among 197 slit-skin smear samples from untreated or relapsed patients, we found three cases of primary resistance to rifampin and one confirmed case of multidrug resistance.

Molecular basis of rifampin resistance in Mycobacterium leprae.
Rifampin is currently the most potent drug used in leprosy control programs. We show that the rifampin resistance which emerged in nine patients with lepromatous leprosy, who had received rifampin monotherapy, stemmed from mutations in the rpoB gene, which encodes the beta subunit of RNA polymerase of Mycobacterium leprae. In eight cases missense mutations were found to affect a serine residue,...

Despite more than three decades of multidrug therapy (MDT), leprosy remains a major public health issue in several endemic countries, including India. The emergence of drug resistance in Mycobacterium leprae (M. leprae) is a cause of concern and poses a threat to the leprosy-control program, which might ultimately dampen the achievement of the elimination program of the country. Rifampicin resi...

For advanced control of leprosy in Pakistan where the World Health Organization leprosy elimination goal was achieved in 1996, we conducted surveillance of Mycobacterium leprae-seropositive patients and their contacts and drug resistant strains of M. leprae. We measured anti-PGL-I antibody level in sera from leprosy patients and their contacts for early detection of M. leprae infection. Out of ...
متن کاملEvaluation of Gene Mutations Involved in Drug Resistance in Mycobacterium Tuberculosis Strains Derived from Tuberculosis Patients in Mazandaran, Iran, 2013
Drug resistance (especially multiple drug resistance) in Mycobacterium tuberculosis makes global concerns in treatment and control of tuberculosis. Rapid diagnosis of drug resistant strains of the bacteria has vital importance in the prognosis of the disease. The aim of this study was to identify the mutations responsible for drug resistance in Mycobacterium tuberculosis strains derived from pa...
متن کاملMutation analysis of mycobacterial rpoB genes and rifampin resistance using recombinant Mycobacterium smegmatis.
Rifampin is a major drug used to treat leprosy and tuberculosis. The rifampin resistance of Mycobacterium leprae and Mycobacterium tuberculosis results from a mutation in the rpoB gene, encoding the β subunit of RNA polymerase. A method for the molecular determination of rifampin resistance in these two mycobacteria would be clinically valuable, but the relationship between the mutations and su...
