Mycobacteria are ubiquitous in the environment, but they are not part of the normal human microbial flora. It has been suggested that variable contact with mycobacteria can influence susceptibility to mycobacterial pathogens and the efficacy of subsequent Mycobacterium bovis BCG vaccination. To test this, mice were immunized with high or low doses of an environmental saprophyte, M. vaccae, that...

Introduction: Determination of produced cytokines, especially interleukin 10, interleukin 12, interferon gamma and TNF-α is an important tool in the review of safety responses against inducers such as illnesses. The purpose of this study was to investigate the immune system status in patients with mycobacterium infections such as tuberculosis and non-tuberculosis as compared to healthy controls...
The potentially pathogenic Non-Tuberculosis Mycobacteria (NTM) are emerging nowadays which result in pulmonary and non-pulmonary infections in human. This group of bacteria consists of at least 200 different species. While the pulmonary disease is the most common form of NTM infections, NTM can cause diffused infections as well as extrapulmonary infections in every organ, such as bone marrow, s...
a case of mycobacterium marinum infection of the nasal cavity is described. a 57 years old man was being on infliximab for 2 years for severe psoriasis presented with five months history of epistaxis, nasal blockage and snoring. local examination revealed bilateral nasal mass. the diagnosis of mycobacterial infection was suspected based upon the histopathological finding of granuloma in the bio...
background and objectives: sub-minimum inhibitory concentration (s-mic) can induce changes in morphology, virulence factors and biochemical properties ofbacterial pathogens. the goal of this study is to determine the sub-mic effect of ciprofloxacin and ampicillin on the haemotytic activity of e. coli. material and methods:two clinical isolates of e. coli with high heamolytic activity was select...
TB remains a global health challenge and, until now, only one licensed vaccine (the BCG vaccine) is available. The main goal of this work to assess the progress in development new vaccines and highlight research nanovaccines. A review was conducted using methodology with appropriate keywords inclusion exclusion criteria. search revealed 37 clinical trials that were further reviewed. results ava...
Abstract Background and objectives: Identification and monitoring of multidrug-resistant Mycobacterium tuberculosis strains (MDR) is highlighted by the high risk of their spreading in different areas. Prevalence of these strains was evaluated in Golestan province in northeast of Iran. Material and Methods: Drug susceptibility testing to Isoniazid and rifampin was carried out for 148 clinical sa...
i Rapiddentification of atypical mycobacterium(Non-tuberculosis mycobacterium NTM) is important because of increase of these organisms infection in recent years. As phenotypic tests are time consuming and expensive, nowadays the molecular methods are widely used for rapid identification of mycobacterium spcies. The aim of this study was molecular differentiation of atypical mycobacteria usin...
