sarcocystis is one of the most prevalent parasites of domestic ruminants worldwide. this study was aimed to determine prevalence of sarcocystis infection and molecular discrimination of sarcocystis gigantea and sarcocystis medusiformis infecting domestic sheep. tissue samples from 638 sheep slaughtered at urmia abattoir were randomly collected from february 2011 to january 2012. genomic dna ext...

onion thrips, thrips tabaci lindeman, is a broadly distributed pest that attacks a wide range of crops. to investigate the intra-specific morphometric variation and the genetic diversity of the species in iran, four populations from tobacco plus 18 populations from onion were studied in some 17 provinces of iran. morphological analysis, using principal components and canonical discriminant anal...

background and aims: rotaviruses are the main cause of gastroenteritis in the young of human and a variety of animals in the world. rotavirus g6 and g10 are the most prevalent genotypes in cattle worldwide, but are also found in human with possible origination from animals. materials and methods: in this work, we have detected the g6 and g10 genotypes of bovine rotaviruses isolated from diarrhe...

dirofilaria immitis is an important filarial nematode in dogs. in this study, age and sex distribution of this zoonotic nematode among dogs were investigated in northwest of iran in meshkin-shahr city. molecular characteristics of the isolates, based on cytochrome oxidase subunit 1 (cox1) gene were compared to the isolates from other areas of the world.blood samples were collected from 91 dogs ...

the flowering and fructification period of the chilean strawberry (fragaria chiloensis (l.) duch.) is restricted to approximately 2 mo, which seriously limits the commercial development of the species. the objective of the current investigation was to identify inter simple sequence repeat (issr) polymorphisms associated with flowering duration in accessions of f. chiloensis. the flowering durat...

having knowledge about genetic relationships among accessions is necessary for developing breeding strategies to produce improved cultivars. in present study, genetic diversity and inter-relationship among 29 genotypes of citrus were comparatively analyzed using morphological and rapd markers. significant variability was observed among citrus genotypes for 61 quantitative and qualitative morpho...
