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...

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...

recent studies have indicated that 1, 4-dihydropyridine-3, 5-dicarboxamidederivativesshow significant anti-tubercular activity. in this research, new derivatives of 1, 4-dihydropyridine were designed and synthesized using hantzsch condensation in which dicyclohexyl and different dicyclohexylcarbamoylwere substituted at c-3 and c-5 positions of the dhp ring.in addition, 4 (5)-chloro-2-methyl-5 (...

introduction an unusual incidence of tuberculosis in different parts of the body is called tuberculomas. the rate of brain tuberculosis is rare. case presentation the following case of tuberculamas of the brain, presented by enhancing rings of meninges, is reported because of its rarity. it was a case of brain tuberculomas in a 15-year-old girl with primary symptoms of headache and general weak...

TYPE: Case Report TOPIC: Chest Infections INTRODUCTION: Bronchopulmonary sequestration (BPS) is a rare congenital malformation of the lower respiratory tract; it consists nonfunctioning mass lung tissue that irrigated by an anomalous systemic artery.

Cutaneous tuberculosis (cTB) represents 1-2% of extrapulmonary [1] and is caused by the Mycobacterium tuberculosis complex (M. tuberculosis, M. bovis, africanum, microti, canetti, caprae, pinnipedii).

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...
