Abstract Background and Objective: A high level of homogeneity observed within all bacteria in the Mycobacterium tuberculosis complex makes a property that seriously challenges traditional biochemical-based identification methods of these pathogens in the laboratory. The work presented here was conducted to characterize Mycobacterium tuberculosis complex isolates in Golestan, Northern Iran. ...
background: fusobacterium necrophorum as a non-spore-forming gram-negative anaerobic bacillus is an important human and animal pathogen. it may cause severe systemic infections (lemierre's syndrome) and some other infections. the aim of this study was to subtype fusobacterium necrophorum by using pcr methods. materials and methods: twenty five strains of fusobacterium necrophorum subspecies fun...
The analysis of mitochondrial DNA (mtDNA) hypervariable region (HVR) sequence data from ancient human remains provides valuable insights into the genetic structure and population dynamics populations. mtDNA is particularly useful in studying populations, because it maternally inherited has a higher mutation rate compared to nuclear DNA. To determine three Colombian pre-Hispanic populations comp...
background and purpose: by using advanced detection/identification methods, the list of emerging uncommon opportunistic yeast infections is rapidly expanding worldwide. our aim in the present study was sequence-based species delineation of previously unidentified yeasts obtained from a clinically yeast collection. materials and methods: a total of twenty three out of the 855 (5.7%) yeast isolat...
Conidia of Aspergillus species are widely distributed and ubiquitous in outdoor and hospital environments. There are high numbers of patients with weakened immune systems, therefore Aspergillus infections are increasing in hospitals. Molecular typing of Aspergillus strains obtained from patients and their environment is an important tool for epidemiological and public health studies. Fingerprin...

زمینه و هدف : روش miru-vntr به یکی از فراگیرترین روش های استاندارد شده ژنوتایپینگ مایکوباکتریوم توبرکلوزیس کمپلکس تبدیل شده است. این مطالعه به منظور تعیین ساختار ژنتیکی مایکوباکتریوم توبرکلوزیس به روش miru-vntr و نیز تعیین نقش اعضای دیگر مایکوباکتریوم توبرکلوزیس کمپلکس در ایجاد بیماری سل انجام گردید. روش بررسی : این مطالعه توصیفی روی 53 جدایه حاصل از کشت باکتریایی نمونه های خلط و لاواژ معدی بیم...
Strongyloides stercoralis is the causative agent of strongyloidiasis, which affects more than 300 million people worldwide [1]. Canine strongyloidiasis is also caused by the same species, S. stercoralis of an animal origin with up to 50% worldwide prevalence [2–5]. It is known that human S. stercoralis strains can infect dogs in laboratory settings (dogs have to be immunosuppressed to maintain ...
