BACKGROUND/AIM The purpose of the present study was to determine the distribution and epidemiological features of mycobacteria with molecular methods. MATERIALS AND METHODS Fifty-five culture-positive samples were analyzed by polymerase chain reaction-restriction enzyme length polymorphism (PCR-RFLP) at species level, and their molecular typing was performed with spoligotyping. The IS6110 reg...

A new convenient molecular typing method, simultaneous polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) analysis, for three different genes of methicillin-resistant Staphylococcus aureus (MRSA) was evaluated using 35 isolates of MRSA and comparing results with those previously reported for sequencing-based spa typing. Twenty-nine isolates of the most frequent prot...

We describe the use of two insertion sequence elements (ISFtu1 and ISFtu2) in Francisella tularensis to type strains by restriction fragment length polymorphism (RFLP). The RFLP profiles of 17 epidemiologically unrelated isolates were determined and compared. Our results showed that RFLP profiles can be used to assign F. tularensis strains into five main groups corresponding to strains of F. tu...

Growing consumer awareness is forcing food producers to supply raw material and products of increasingly high quality health-promoting properties. Knowledge the genetic background characteristics taking on great importance, enabling selection based molecular markers. The increasing throughput techniques, in combination with an expanding bioinformatics infrastructure, leading continual improveme...

BACKGROUND Enterococci are opportunistic pathogens and are a major factor in nosocomial infections. They may contain ebp operon, which upon expression makes them highly prone to biofilm formation on biotic and abiotic surfaces. OBJECTIVES The aim of the current study was to detect the polymorphism of ebp genes in Enterococcus faecalis. MATERIALS AND METHODS Samples were isolated from patien...

background: henoch-schönlein purpura (hsp) is an lga mediated small vessel systemic vasculitis disease in children. the etiology and pathogenesis of hsp disease remain unknown. however, environmental and genetic risk factors could play important roles in susceptibility to hsp disease. in this study we investigated the association of 5՛-untranslated region polymorphism (-634g/c) of vegf gene wit...

In the present investigation, 49 Aspergillus fumigatus isolates obtained from four nosocomial outbreaks were typed by Afut1 restriction fragment length polymorphism (RFLP) analysis and three PCR-based molecular typing methods: random amplified polymorphic DNA (RAPD) analysis, sequence-specific DNA primer (SSDP) analysis, and polymorphic microsatellite markers (PMM) analysis. The typing methods ...

Introduction: The most common cutaneous fungal infections are caused by dermatophyte fungi such as Microsporum, Trichophyton, and Epidermophyton. In this study, the epidemiologic trends predominant organisms causing dermatophytosis in Urmia, Northwest Iran, were identified.Aims objectives: To get better perception of distribution authors studied identification isolated dermatophytes from human ...

There is an increasing interest about studying possible effects of genetic polymorphisms and risk of cancer progression. E-cadherin (CDH1) involves in many important cellular processes including cell-cell interactions, cell development and genetic changes of this molecule has been associated with greater tumor metastasis. The present study was aimed to evaluate the possible role of CDH1 -160 C/...
