background: to evaluate immunotherapy against canine visceral leishmaniasis, leishmania major antigen and heat-killed mycobacterium vaccae (srl172) were used as stimulators of immune defense mechanisms and the results were compared with standard chemotherapy meglumine antimoniate. methods: nineteen mongrel dogs aging 1-3 years old were used in this experiment. infection was carried out in 15...
isoniazid, is the only antituberculous drug for which the relation between lack of virulence and acquisition of resistance was associated. inh-resistant mutants were shown to contain defective katg gene. classical studies showed that inh-resistant south indian isolates have lower virulence in guinea pigs and higher susceptibility to h2o2. it is of interest to assess the virulence in south india...
background: tuberculosis (tb) is a major cause of death worldwide. finding an effective vaccine against tb is the best way to control it. several vaccines against this disease have been developed but none are completely protective. the aim of this study was to design and construct a cloning vector containing the mycobacterium tuberculosis (m. tuberculosis) heat shock protein x (hspx). methods: ...
in most countries, tuberculosis caused by mycobacterium bovis is mainly a disease of cattle but can infect buffalos too. the disease can be controlled successfully by mean of a test-and-slaughter program. in iran test-and-slaughter program has started since 1971 and prevalence of bovine tuberculosis reduces from 5% to less than 0.12% in recent years. in western azarbaijan, north west of iran, t...
زمینه و هدف: امروزه اهمیت بیماریزایی مایکوباکتریوم های غیرکلوزیس (Non-Tuberculosis Mycobacterium) برای انسان مشخص گردیده است. بطور کلی این گروه علاوه بربیماریزایی در دستگاه تنفس، از قدرت بیماریزایی درغدد لنفاوی، پوست، بافت نرم، استخوان ها برخوردار است. تعیین هویت مایکوباکتریاها بر اساس کشت و تستهای بیوشیمیایی هفته ها طول میکشد و درتشخیص قطعی به ما کمک نمی کند. تکنیک PCR-RFLP (PRA ) از ژن hsp65 ...
Background and Objective: Tuberculosis (TB) is amongst the common infectious diseases in the world so that the World Health Organization (WHO) has declared it as a global emergency as well as an extremely contagious disease. Although the cause of the disease and its therapy are well known, TB is considered as a global dilemma. The present study was set to isolate and identify Mycobacterium Tube...
Abstract A dataset of (E)-N’-benzylideneisonicotinohydrazide derivatives as a potent anti-mycobacterium tuberculosis has been investigated utilizing Quantitative Structure-Activity Relationship (QSAR) techniques. Genetic Function Algorithm (GFA) and Multiple Linear Regression Analysis (MLRA) were used to select the descriptors and to generate the correlation QSAR models that relate the Mi...
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...
conclusions results of the current study showed the high prevalence of m. tuberculosis among the patients with lung cancer; therefore, it seems that continuous surveillance is essential to monitor the m. tuberculosis in the patients with lung cancer. results the subjects included 252 (66.3%) males and 128 (33.7%) females. based on cultural and microscopic methods, m. tuberculosis infection was ...
discussion transthoracic echocardiography disclosed massive pericardial effusion, respiratory variation in mitral and tricuspid inflow e velocity, increased diastolic flow reversal with expiration in the hepatic vein, septum deviation in inspiration toward the left ventricle (lv), preserved lv function, and inferior vena caval (ivc) dilation without any collapse in inspiration. chest computed t...
