A case is presented of coinfection with Mycobacterium malmoense and Mycobacterium tuberculosis in a Cuban patient with AIDS which produced respiratory and liver disease respectively. Cultures done from sputum samples showed the presence of a non-pigmented, slow growing mycobacterial strain belonging to Runyon group III and identified as Mycobacterium malmoense. From cultures of liver tissue rem...

At the time macrophages phagocyte against Mycobacterium tuberculosis entry, it occurs respiratory burst, and become the initial formation of reactive oxygen species (ROS). Reactive oxygen species such as nitric oxide and oxygen radicals kill the mycobacterium bacteria. However, Mycobacterium tuberculosis has an antioxidant that plays a role in redox homeostasis system which protects itself from...

A standardized clarithromycin susceptibility test for Mycobacterium genavense is reported. The BACTEC radiometric broth dilution test method recommended for Mycobacterium avium complex was modified to develop a reliable and reproducible procedure. Test development involved optimization of medium pH and inoculum densities for antibiotic vials as well as growth control vials. MIC control organism...

background and aims: infectious diseases are disorders caused by organisms such as bacteria, viruses, fungi or parasites .the th9 subset develops in response to combined signals from tgf-b and il-4 among a cacophony of other cytokines in the extracellular milieu.t helper 9 (th9) cells,a novel cd4 t cell subset, seem to play a complex role in the outcome of specific immune responses. in this art...

objective: antigen 85 complex of mycobacterium tuberculosis includes three immunogenic proteins which are important tb vaccine candidates. the use of these protein as a component of subunit vaccines, as a part of dna vaccines or recombinant bcg boosters, enhances their recombinant production. recombinant production of these mycobacterial proteins located in the cell wall somehow differs from th...

conclusions subcutaneous nodules in the absence of a local reaction at the site of bcg vaccination may be the sole manifestation of disseminated bcg disease. case presentation we report on an 11-months-old boy with prolonged fever and diffuse hyperpigmented subcutaneous nodules. due to lymphopenia, oral thrush and severe adverse reaction to bcg vaccination, the possibility of primary immunodefi...

molecular isolation of biodegradable mycobacteria from water supplies of iranian hospitals background and objectives: some microorganisms, mainly members of two genera including pseudomonas and mycobacterium , were found to be capable of transforming and degrading of polluting agents. we herein report the isolation of a few mycobacteria with the ability to biodegrade organic and inorganic compo...

conclusions the results of the current study showed a high rate of co-infection of m. tuberculosis and p. jirovecii in the iranian patients with hiv. as the immune system condition worsened, the probability of occurrence of pneumocystis pneumonia (pcp) increased. therefore, more specific, most rapid and sensitive tests should be utilized for diagnosis of pcp in this group of patients. results a...

We report the draft genome sequence of Mycobacterium obuense strain UC1 from a patient sputum sample. This is the first draft genome sequence of Mycobacterium obuense, a rapidly growing scotochromogenic mycobacterium.

We report the draft genome sequence of Mycobacterium heraklionense strain Davo, isolated from a fine-needle aspirate of a right-ankle soft-tissue mass. This is the first draft genome sequence of Mycobacterium heraklionense, a nonpigmented rapidly growing mycobacterium.
