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...

conclusions concurrent pulmonary nocardiosis and tuberculosis is frequent in hiv-infected patients. rapid and sensitive methods such as pcr are recommended for detection of such co-infections. results from 157 sputum specimens, positive samples by acid fast staining, culture and pcr for m. tuberculosis were reported for 7.6% (12/157), 10.1% (16/157) and 7% (11/157) of samples, respectively. no ...

methods mycobacterium tuberculosis standard strain crbip7.11 was cultured at 37°c in loewenstein johnson (lj) media for 3-4 weeks. to confirm the species, standard microbiological and biochemical tests were performed. after preparation of membrane vesicles, the amount of protein in membrane vesicles was measured by sds-page and nanodrop. to analyze the integrity and morphology of extracellular ...

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...

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. mat...

introduction: development of effective immunodiagnostic methods for detection of mycobacterium tuberculosis infection is crucial. serodiagnostic methods, based on antibody response to specific antigens could provide promising approaches for rapid, economical and easy to perform diagnostic tests which are crucial for tuberculosis (tb) control. in this study, the level of igg antibody responses a...

conclusions with regard to the ease of urine sample preparation and the 100% specificity the pcr method, performing urine pcr could be used as a diagnostic aid in ptb cases obtaining sputum samples is problematic. results results of the current study indicated that 48 (62.3%) patients out of 77 had a positive sputum culture. urine cultures and acid-fast smears were negative. urine pcr-tb was po...

background since tuberculosis (tb) is a major public health problem that is a leading cause of mortality and morbidity among infectious diseases worldwide, early diagnosis and treatment are important to control an effective tuberculosis (tb) and also the increasing number of patients with atypical manifestations of active tb. it suggests more evaluation for active tb in fibrotic lesion in ct sc...

background: resistance to anti-tuberculosis (tb) drugs is a global problem. previous studies showed that the prevalence of primary mdr-tb is higher and has been increasing. the purpose of this study was to determine the primary drug resistance in strains isolated from patients with smear-positive of the new cases to anti-tb drugs. methods: in this cross-sectional study, 266 smear positive pulmo...
