A thorough phenotypic and genotypic analysis of 150 strains belonging to the Mycobacterium terrae complex resulted in the identification of a number of previously unreported sequevars (sqvs) within the species known to belong to the complex. For the species Mycobacterium arupense, three sqvs were detected in the 16S rRNA gene, six sqvs in the hsp65 gene and 15 sqvs in the rpoB gene; in Mycobact...
مقدمه: مایکوباکتریوم آویوم کمپلکس به صورت گسترده در محیط وجود دارند و عامل ایجاد کننده بیماری در حیوانات، پرندگان و بیماران نقص سیستم ایمنی و افراد سالم می باشد. هدف از این مطالعه به کارگیری روش ترادف یابی چند جایگاهی (MLSA) در شناسایی مایکوباکتریوم آویوم کمپلکس بود. روش کار: در این مطالعه، ابتدا توالی ژن های 16S rRNA، rpoB و hsp65 برای 8 زیر گونه از کمپلکس مایکوباکتریوم آویوم از بانک ژنی جمع آ...
زمینه و هدف: باتوجه به اهمیت افزایش بیماری های ناشی از مایکوباکتریوم های غیر سلی در سرتاسر جهان، ما مطالعه ای را به منظور ارزیابی بسامد این بیماری ها در منطقه خود انجام داده ایم. هدف از مطالعه حاضر شناسایی و بررسی میزان شیوع مایکوباکتریوم های غیر سلی در ایران از نمونه های مختلف بالینی، طی یک دوره 8 ساله در بیمارستان مسیح دانشوری بوده است. روش بررسی: این مطالعه به صورت توصیفی بر روی 8322 نمونه ج...
It has been suggested that molecular mimicry between self-(mammalian)-components, such as self-stress, heat-shock proteins (HspIGO 81 bacterial Hsp65 (Mycobacterium [M.] tuberculosis or M. bovisl might be implicated in the human rheumatoid arthritis IRA) --an autoimmune inflammatory joint disease, which is characterized by infiltration of lymphocytespredominantly of the T lineage in the synovia...
Mycobacterium avium complex (MAC) species cannot be discriminated by the usual methods of biochemical identification of mycobacteria. This study showed that amplification by PCR of DT1 and DT6, two single copy sequences identified in the genome of M. avium serotype 2, the insertion sequence IS1245, found to be consistently present in M. avium strains and the heat-shock protein gene hsp65, follo...
Resistant C57BL/6 mice infected in the lungs with Mycobacterium tuberculosis and then therapeutically vaccinated with Mycobacterium leprae-derived hsp65 DNA develop severe granulomatous pneumonia and tissue damage. Analysis of cells accumulating in the lungs of these animals revealed substantial increases in T cells secreting tumor necrosis factor alpha and CD8 cells staining positive for granz...
In this article, the first isolation of Mycobacterium kyorinense specimens in Brazil is described. M. kyorinense is a recently identified species, with a few strains reported only in Japan. The Brazilian isolates were initially identified as Mycobacterium celatum by PCR restriction enzyme pattern analysis (PRA) with hsp65. However, biochemical tests indicated the same profile of M. kyorinense a...
We report the first Korean case of lung diseases caused by Mycobacterium abscessus subsp. bolletii in a previously healthy male, except for a previous history of pulmonary tuberculosis and bronchiectasis. All serial isolates are identified as M. abscessus subsp. bolletii by multi-locus sequence analysis based on the hsp65, rpoB, and 16S rRNA fragments. At the genetic level, the isolate has the ...
A Gram-positive, rod-shaped acid-fast bacterium was isolated from a patient with a post-traumatic chronic skin abscess associated with osteitis. Morphological analysis, 16S rRNA, hsp65, sodA and rpoB gene sequence analysis, cell-wall fatty acid and mycolic acid composition analyses and biochemical tests showed that the isolate, designated ABO-M06(T), belonged to the genus Mycobacterium. Its phe...
