thrips tabaci lindeman is an extensively distributed pest insect in many areas that affects plants through direct feeding and at the same time, it makes damage as a vector of different viruses. as a basic first step to control pests is authentic identification, but the inability to determine morphological characters of thrips species makes this process very difficult. for creating an identifica...

the identification of mycobacteria in the species level has great medical importance. biochemical tests are laborious and time-consuming, so new techniques could be used to identify the species. this research aimed to the comparison of biochemical and sequencing 16s rdna gene methods to identify nontuberculous mycobacteria in patients suspected to tuberculosis in golestan province which is the ...

pythium species are cosmopolitan, fungus-like oomycotes which may cause diseases in plants, animals and even human beings. some of the species, however, are saprophytes and also well-proven biological control agents of plant pathogenic fungi. since 1968, when the first pythium species was reported from iran, ca 44 species, two varieties, and five groups of this genus have been reported from dif...

Abstract Background and Purpose: Candida parapsilosis is a common cause of candidemia in children and onco-hematologic patients as well as in patients with septic arthritis, peritonitis, vaginitis, and nail and skin infections. Here, we evaluated intra- and inter-species beta tubulin DNA sequence variation within the C. parapsilosis complex with a view to establishing its utility in the identi...

Background: Traditional dairy products are the main sources for probiotic bacteria. This study aimed to isolate and characterize the potentially probiotic Lactobacillus strains isolated from traditional dairy products in Iran. Methods: Microbial population of each dairy product was enriched and screened for acid- and bile- resistant strains. The isolates were ...

Background: Classical bacteriological detection of Brucella species from food, and environment is routinely carried out based on morphological and biochemical characteristics. However, for increasing specificity and sensitivity of species identification methods, development of a molecular assay is necessary that was main aim of this study. Methods: Panel of some reference strains belonging to ...

the parasitoid wasps of the genera leiophron nees and euphorus nees were studied in northern iran (guilan, mazandaran and alborz provinces). the specimens were collected using malaise traps from different habitats during 2010-2011. four species of both genera were collected and identified, of which three species, euphorus pallidistigma (curtis), e. similis (curtis) and leiophron fascipennis (ru...

Species of Phyllosticta are important group of pathogenic and endophytic fungi that are reported from various crop plants, ornamental and non-fruiting plants. These fungi cause several diseases such as leaf and fruit spots and fruit rot. In order to identify Phyllosticta species in Guilan province, several collections were examined around the region. Altogether 14 taxa were isolated from differ...

Five taxa of Lepiota, namely, L. anthomyces, L. serena, L. metulaespora, L. roseoalba and L. cristata were collectedfrom different localities are described in details. Microscopic and macroscopic descriptions along with drawings are given for all the five species. Of  these   L. anthomyces, L. serena, L. metulaespora and L. roseoalba,are newly recorded for Iranian fungus flora.
