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...
background : multi drug-resistant mycobacterium tuberculosis (mdr-tb) is an infection with a causative bacillus which is resistant to at least two drugs, isoniazid and rifampin. the purpose of this study is to evaluate the prevalence of tb resistance to first-line drugs of newly diagnosed active pulmonary tuberculosis. methods : this cross-sectional study was performed on 77 patients with newly...
Background and purpose: Hepatotoxicity and elevated serum aminotransferase is a severe side effect of anti-Tuberculosis therapy and some cases could even develop hepatitis. This study aimed at determining the prevalence of drug induced hepatitis and predisposing factor after anti-Tuberculosis therapy in Razi hospital. Materials and methods: In this cross-sectional study we used the medical ...
a modified pulsed-field gel electrophoresis (pfge) protocol was developed and applied to clinical isolates of mycobacterium tuberculosis complex to reduce the cost of using lyticase. this protocol reduces the expense of pfge typing of mycobacterium tuberculosis complex as it removes the use of lyticase during the spheroplast formation from these bacteria.
Background and purpose: The incidence of tuberculosis (TB) in Iran is about 13 in 100000 people and this rate in Golestan and Sistan & Balouchestan Provinces is the highest. Due to the proximity of Golestan to Mazandaran, this epidemiological survey has been done to identify the high risk locations by using of disease mapping of tuberculosis incidence rate. Materials and methods: This obse...
background: human immunodeficiency virus (hiv) makes infected cases prone to opportunistic infections like tuberculosis (tb) due to impaired immunity of the body, especially multi drug resistant (mdr) ones which are a major concern. with hiv outbreak starting late in the 20th century, the international health community is observing a huge rise in the incidence of this complex disease. herein, w...
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...
background: predicting the incidence of tuberculosis (tb) plays an important role in planning health control strategies for the future, developing intervention programs and allocating resources. objectives: the present longitudinal study estimated the incidence of tuberculosis in 2014 using box-jenkins methods. materials and methods: monthly data of tuberculosis cases recorded in the surveillan...
Drug resistant tuberculosis (DR-TB) has been reported since the early days of introduction of antitubercular chemotherapy, but recently multi drug resistant tuberculosis (MDR-TB), has been an area of growing concern, and is posing threat to global efforts of tuberculosis control. Prevalence of MDR-TB, in a community mirrors the functional state and efficacy of tuberculosis control programme and...
Drug-resistant tuberculosis is a major public health problem. The aim of this study was to assess the local susceptibility patterns of Mycobacterium tuberculosis and clinical outcomes of drug resistant tuberculosis (DR-TB) at Srinagarind Hospital, a tertiary care center in northeastern Thailand. Between January 2004 and December 2008, 1,052 patients had culture-proven M. tuberculosis infections...
