In this study, molecular characterization of Echinococcus granulosus sample obtained from water buffalo originating from southwest of Iran was performed using comparative sequence analysis of cox1 mitochondrial gene. DNA was extracted from protoscoleces removed from hydatid cyst from the liver of a 2-year-old male buffalo slaughtered in Khuzestan province. Molecular and phylog...

30 milled rice samples were collected from retailers in four states of Malaysia. These samples were evaluated for Eurotium spp. contaminations by direct plating on malt extract salt agar (MESA). All Eurotium were isolated and identified based on morphology and nucleotide sequences of internal transcribed spacer 1 (ITS1) and ITS2 of the rDNA.  Four Eurotium species (E. rubrum, E. amstelodami, E....

background : strongyloides stercoralis is a prevalent parasite in some rural areas in the north of iran. we decided to investigate whether the 18s ribosomal dna sequence of the parasite in iran is similar to the findings of the other re­searchers. methods :  we collected 3514 stool samples from gilan and mazandaran, northern iran, during the year 2005-2006, from which 96 were found infected wit...

Simple sequence repeat (SSR markers or microsatellites), based on the specific PCR amplification of DNA sequences, are becoming the markers of choice for molecular characterization of a wide range of plants because of their high polymorphism, abundance, and codominant inheritance. Different methods have been used for the analysis of the SSR amplified fragments being submarine agarose electropho...

Background and Aims: Tomato yellow leaf curl virus (TYLCV) is one of the most destructive viruses of tomato that leads to reduced tomato yield up to 100% in tropical and subtropical regions. In this study, the complete sequence of TYLCV isolate from Hormozgan province, Iran and its recombination evsent was determined. Methods: TYLCV infected tomato was collected from Hormozgan province. Total D...

A reliable DNA extraction method for use on extra virgin olive oil based on a commercial kit was defined, and the possibility of using this DNA for fingerprinting the original cultivar was demonstrated. The genetic traceability of single-cultivar virgin olive oil from two cultivars (Carolea and Frantoio) was achieved by identifying the varieties from which they were produced. This involved the ...

background: approximately 85-90% of malaria infections in iran are attributed to plasmodium vivax , while little is known about the genetic of the parasite and its strain types in this region. this study was designed and performed for describing genetic characteristics of plasmodium vivax population of iran based on the merozoite surface protein-3α gene sequence. methods: through a descriptive ...
