PURPOSE Malassezia yeasts are globally distributed agents of pityriasis versicolor and are implicated in the pathogenesis of seborrhoeic and atopic dermatitis. The aim of this study is to identify the Malassezia species obtained from pityriasis versicolor patients, using morphological, biochemical, physiological as well as Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-...

introduction: anthroponotic cutaneous leishmaniasis (acl) is still a major public health problem in the northeast and central parts of iran. this study was designed to compare microscopy and cultivation methods with pcr amplification of kinetoplast dna and its1 followed by rflp analysis for diagnosis of acute and chronic acl. methods: in this study, 66 patients with acl including 24 acute and 4...

background: we evaluated the genetic diversity of samples identified morphologically as fasciola spp. from sheep, cattle and goat from kermanshah province, western iran using pcr-rflp method. methods: we used pcr-rflp analysis of ribosomal its1 fragment using rsai restriction enzyme to investigate the genetic characteristics of fasciola species obtained from different hosts (16 sheep, 28 cattle,...

BACKGROUND The aim of this study was DNA extraction from protoscolecses of Echinococcus granulosus and identification of these strains in West-Azerbaijan Province, north western Iran. METHODS Thirty one livestock isolates from sheep and cattle were collected from abattoirs of the province. To investigate the genetic variation of the isolates, after DNA extraction by Glass beads-phenol chlorof...

Background: Dermatophytes are the most common fungal agents causing superficial skin infections in worldwide. Species identification of these fungi is important for therapeutic and epidemiological apects. The purpose of this study was to determine the epidemiology of dermatophytosis in patients referring to medical mycology laboratory of Razi hospital in Tehran, during 2014. Materials and Meth...

background: fusarium species are capable of causing a wide range of crop plants infections as well as uncommon hu­man infections. many species of the genus produce mycotoxins, which are responsible for acute or chronic diseases in ani­mals and humans. identification of fusaria to the species level is necessary for biological, epidemiological, pathologi­cal, and toxicological purposes. in this s...

BACKGROUND & OBJECTIVE Cystic echinococcosis (CE) has a wide host range and distinct entities, not only reflected phenotypically but also by genotypic variation. Considering this fact, this study was undertaken to characterize the Indian isolates of Echinococcus granulosus to find out difference between Indian cattle, buffalo and sheep isolates on the basis of random amplification of polymorphi...
