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...

We have identified based on gene cluster analysis that the genes between Rv3799-Rv3807 in M. tuberculosis have orthologs in Corynebacteria, Mycobacteria and Nocardia (CMN) genomes. Therefore, this gene cluster possibly corresponds to the 'Ancient Conserved Region' of CMN mycolyltransferases. The evolutionary trace analysis suggests that twelve amino acid residues; Leu39, Trp51, Pro71, Trp82, Tr...

In summary, in order to control tuberculosis, we require a rapid diagnosis of TB patients, who act as the source of disease; and if remain untreated, these patients can spread the disease throughout the population. Therefore, we need to introduce the new approach for quick and accurate identification of Mycobacterium tuberculosis, and CYP141 gene is a new approach for rapid and accura...

Two regions of the gene coding for 16S rRNA in Nocardia species were selected as genus-specific primer sequences for a PCR assay. The PCR protocol was tested with 60 strains of clinically relevant Nocardia isolates and type strains. It gave positive results for all strains tested. Conversely, the PCR assay was negative for all tested species belonging to the most closely related genera, includi...

conclusions the detection of mycobacterium tuberculosis is always an important differential diagnosis for skin and soft tissue involvement in endemic areas. the cold abscess is an uncommon form of cutaneous tuberculosis that can be single or multiple and with or without fistula. case presentation the case was a 42-year-old female, a known case of rheumatoid arthritis that was receiving predniso...

extrapulmonary tuberculosis is a complication of pulmonary tuberculosis that is disseminated through hematogenous or lymphatic system and may involve any organs. we present a case of primary tuberculosis of the penis that is a very rare presentation of tuberculosis. patient the patient was a 43-year-old man who had kidney transplantation. he admitted with painful ulceration on the glans of peni...

tuberculosis (tb) is one of the most important aids associated infectious diseases worldwide. it is a leading cause of illness and death among people with hiv/aids in resource-poor areas of the world. the annual incidence of tb among indigenous iranians stands at 14 cases per 100,000 inhabitants. this study aimed to identify mycobacterium infection among iranian hiv positive patients. two sputu...

Tuberculosis is an infectious disease caused by the germ Mycobacterium tuberculosis. The group of bacteria in addition to tuberculosis that can cause disorders airways known as MOTT (Mycobacterium Other Than Tuberculosis), which sometimes interfere with enforcement TB diagnosis and treatment. (TB) a high burden for Indonesia, not only because itself, but also its resistant several first-line dr...
