BACKGROUND Typing of nosocomial pathogens is necessary to determine the source of an outbreak. The aim was to determine the genomic variability among Pseudomonas aeruginosa (P. aeruginosa) by random amplification of polymorphic DNA (RAPD) and enterobacterial repetitive intergenic consensus (ERIC) methods. METHODS Fifty P. aeruginosa isolates were obtained from the hospitals. The source of the...

بیماری سیاهک پنهان جو توسط قارچ بازیدیومیستustilago hordei (pers.) lagerh. ، ایجاد می شود و از اغلب مناطق کشت جو در جهان گزارش شده است. این بیماری علاوه بر کاهش محصول در واحد سطح، از ارزش غذایی تعذیه ای محصولات نیز می کاهد و یکی از عوامل محدود کننده تولید جو در ایران به شمار می رود. با توجه به اهمیت بیماری و عدم وجود اطلاعات جامع و کامل پیرامون ساختار ژنتیکی جمعیت های این بیمارگر در استان خوزست...

بیماری پوسیدگی ذغالی سویا که به وسیله قارچ macrophomina phaseolina ایجاد می شود، یکی از مخرب ترین بیماری های سویا در سطح جهان می باشد. در ایران نیز این بیماری در بسیاری از مناطق کشت سویا، خسارت قابل توجهی را به این محصول وارد می کند. به منظور بررسی تنوع ژنتیکی و بیماریزایی در جمعیت این بیمارگر، در سال 1385 مناطق کشت سویا در استان های گلستان، مازندران، اردبیل و لرستان مورد بازدید قرار گرفت. نمون...

PCR-based fingerprinting using random amplified polymorphic DNA (RAPD) has been used widely for genome identification. In this study, 13 Salmonella Typhi strains were isolated from typhoid patients from Aswan, Cairo, Fayoum, and Monofya Governorates of Egypt. The isolates, along with three reference strains, i.e., O901, H901, and Ty2 were subjected to whole genome typing by RAPD PCR. Three RAPD...

Abstract Random amplified polymorphic DNA-PCR (RAPD-PCR) is a technique successfully used to generate characteristic fingerprints of different bacteria. Bacillus genus that includes heterogeneous species, thus combination techniques essential for their identification. Here we RAPD-PCR methodology distinguish among genetically similar strains and evaluate the genetic diversity species from Salar...

PCR-based DNA fingerprinting was used to characterize 48 clinical isolates of Yersinia enterocolitica. The samples were examined by random amplified polymorphic DNA (RAPD-PCR) and inter-repeat PCR (IR-PCR). IR-PCR with two enterobacterial repetitive intergenic consensus primers resulted in patterns which were poorly discriminated; 2 of 11 arbitrary primers (RAPD-PCR) provided sufficient discrim...

This study was conducted to determine whether there was any genetic heterogeneity among Helicobacter pylori strains isolated from the antrum and corpus of the same individual in a Malaysian population and to determine the presence of heterogeneous susceptibility of the isolates by comparing PCR-RAPD and antibiotic profiles. Forty-four H. pylori isolates cultured from the antrum and corpus of 22...

Edwardsiella tarda is an enterobacterial fish pathogen that causes mortality in various fish species worldwide. In this study, we analyzed the intraspecific variability in a collection of E. tarda strains isolated from turbot. To do this we employed 4 polymerase chain reaction (PCR)-based methods: (1) random amplified polymorphic DNA (RAPD), (2) enterobacterial repetitive intergenic consensus-P...

Random-amplified-polymorphic-DNA(RAPD) was assayed to detect the genetic variation of 6 barley generations from Iraq. Four primers generated a total 17 scoreable bands in RAPD analysis) and resolving power, three polymorphic differed (Rp). The use marker systems distance among generation discovered be beneficial. dendrograms indicate diverse grouping barely specimens, although we did see that c...
