the increasing incidence of multi drug resistance tuberculosis (mdr-tb) and extensively drug resistance tb (xdr-tb) worldwide highlight the urgent need to search for newer anti-tuberculosis compounds. it has been determined that pharmaceutical plant, hops ( humulus lupulus ), possesses some antibacterial effect. in this study, the antimycobacterial effect of this plant on rifampin sensitive and...
Several reports have indicated that infection with Non-Tuberculosis Mycobacteria (NTM) is increasing worldwide.Therefore,monitoring species causing micobacterial infection in any region is of great importance. This study was going to detect, differentiate, and identify pathogenic mycobacteria in primary clinical samples. Eighty samples collected from tuberculosis suspected patients in Isfahan/I...
Background and purpose: Mycobacterium tuberculosis complex (MTBC) members are causative agents of human and animal tuberculosis. Differentiation of MTBC members is essential for appropriate treatment of individual patients and reduce drug resistance. Materials and methods: A total of 1345 samples were collected from patients clinically suspected of contracting tuberculosis that referred to hea...
background and objectives: resistance in mycobacterium tuberculosis is caused by mutations in genes encoding drug targets. investigators have already demonstrated the existence of mutations in codons 88 to 94 in the gyra gene and also in codons 1400, 1401, and 1483 of rrs gene among extensively and extremely drug resistant tuberculosis (xdr & xxdr-tb) strains. the aim of this study was to ident...
Abstract Background and Objective: A high level of homogeneity observed within all bacteria in the Mycobacterium tuberculosis complex makes a property that seriously challenges traditional biochemical-based identification methods of these pathogens in the laboratory. The work presented here was conducted to characterize Mycobacterium tuberculosis complex isolates in Golestan, Northern Iran. ...
in this study, substitution at codon ser315 of katg gene, a reliable marker for isoniazid (inh) resistance was analyzed and compared by three molecular methods such as dna sequencing, polymerase chain reaction restriction fragment length polymorphism (pcr-rflp) and pcr-single strand conformation polymorphism (pcr-sscp) in 105 phenotypically resistant isolates obtained from various parts of indi...
Background and Aims: Unlike many global efforts to eradicate tuberculosis caused by Mycobacterium, it remains as a life-threatening infection with a worldwide incidence of 1.5 million cases each year. However, due to the lack of information about Mycobacterium tuberculosis characterization, more studies are required to evaluate strain diversity and epidemiology of tuberculosis to improve the th...
Background: Tuberculosis is still one of the most important causes of mortality and morbidity in many countries and is the second only to human immunodeficiency virus as a cause of death worldwide resulting from a single infectious agent. In 1993, the World Health Organization declared tuberculosis a global public health emergency. Conven-tional methods for the diagnosis of Mycobacterium tuberc...
