BACKGROUND Recurrence of tuberculosis after treatment makes management difficult and is a key factor for determining treatment efficacy. Two processes can cause recurrence: relapse of the primary infection or re-infection with an exogenous strain. Although re-infection can and does occur, its importance to tuberculosis epidemiology and its biological basis is still debated. We used whole-genome...
Background. Considering that Hormozgan province in Iran (southern part of Iran on the Persian Gulf) is among the areas with high prevalence of MDR-MTB and attracts so many sailors and tourists, genetic diversity of MTB isolates circulating in this part of Iran was evaluated. Pattern of TB transmission was also examined. Methods and Material. A total of 38 isolates of MTB were cultured from TB p...
The discovery of an anonymous multiallelic locus in 1980 demonstrated for the first time that the human DNA contains hypervariable regions (Wyman & White, 1980). Eight alleles of a polymorphic locus that was not associated with any known gene were identified during the blot hybridization of total human genomic DNA treated with the restrictase EcoRI with a human DNA fragment (16 tbp in length) i...
BACKGROUND Investigations of Mycobacterium tuberculosis genetic diversity in China have indicated a significant regional distribution. The aim of this study was to characterize the genotypes of clinical M. tuberculosis isolates obtained from Gansu, which has a special geographic location in China. METHODOLOGY/PRINCIPAL FINDINGS A total of 467 clinical M. tuberculosis strains isolated in Gansu...
Background: The variable numbers of tandem-repeat (VNTR) alleles at the phenylalanine hydroxylase (PAH) gene have been used in carrier detection and prenatal diagnosis in phenylketonuria families. This study was carried out to analyze VNTR alleles at the PAH gene in Iranian Azeri Turkish population. Methods: In this study, 200 alleles from general population were studied by PCR. Results: The fr...
