indication of the presence of two distinct strains of echinococcus granulosus in iran by mitochondrial dna markers.sixteen isolates of echinococcus granulosus, collected from iranian patients at surgery, and from domestic animals, including sheep, goats, cattle, and camels at slaughterhouses in tehran and central and southern iran were analyzed for dna nucleotide and predicted amino acid sequence variation within regions of the mitochondrial cytochrome c oxidase i (coi) and nadh dehydrogenase subunit i (ndi) genes. a polymerase chain reaction-restriction fragment length polymorphism method, based on the dna ...19989684648
echinococcosis in the stray dogs of tehran, iran.echinococcus granulosus infections were detected in 29 (48%) of 60 stray dogs from tehran. the adult worms, in a random sample, measured 3.0-7.7 mm in length. the mean, estimated age of the dogs investigated was 5 years, with no significant differences in the prevalences observed in the young, mature and old animals. bad abattoirs and the frequent slaughter of animals in places other than abattoirs appear to be the main reasons for the high prevalence of canine echinococcosis in tehran and elsew ...200010945042
genotype and phenotype of echinococcus granulosus derived from wild sheep (ovis orientalis) in iran.the aim of the present study is to determine the characteristics of genotype and phenotype of echinococcus granulosus derived from wild sheep and to compare them with the strains of e. granulosus sensu stricto (sheep-dog) and e. granulosus camel strain (camel-dog) in iran. in khojir national park, near tehran, iran, a fertile hydatid cyst was recently found in the liver of a dead wild sheep (ovis orientalis). the number of protoscolices (n=6,000) proved enough for an experimental infection in a ...201626951979
genetic characterization of echinococcus granulosus from a large number of formalin-fixed, paraffin-embedded tissue samples of human isolates in iran.cystic echinococcosis (ce), caused by the larval stage of echinococcus granulosus, presents an important medical and veterinary problem globally, including that in iran. different genotypes of e. granulosus have been reported from human isolates worldwide. this study identifies the genotype of the parasite responsible for human hydatidosis in three provinces of iran using formalin-fixed paraffin-embedded tissue samples. in this study, 200 formalin-fixed paraffin-embedded tissue samples from huma ...201525535316
