We report an uncommon case of a primary Echinococcus cyst that developed in the subcutaneous tissue of the right popliteal fossa, at the spot of a previous wasp sting, suggesting the possibility of an unusual transmission of the eggs by insects. This unusual presentation was initially considered as a Baker cyst until parasytological results verified Echinococcus hydatidosus, the larval form of ...

An update on our understanding of molecular variation in Echinococcus and Taenia is provided. Genetic variation within certain species of Echinococcus is now a well accepted phenomenon and a number of intraspecific variants or strains of E. granulosus, in particular, have been characterized hitherto using a range of procedures. Newly acquired molecular information has now been used in epidemiol...

Enzyme electrophoresis was used to examine genetic variation within and between populations of Echinococcus granulosus from domestic and sylvatic hosts in western and eastern Australia. Substantial genetic diversity was found within all populations. There was no evidence, however, of genetic differentiation between populations from different hosts or geographic areas. When isolates were grouped...

b ackground: the aim of the present study was to determine the molecular characteristics of echinococcus granulosus from paraffin-embedded tissues of hydatid cysts isolated from human and protoscoleces of hydatid cysts from sheep, cattle and camel isolates using pcr- rflp of its1- rdna analysis in golestan province, northern iran. m ethods: e . granulosus isolates from human patients infected w...

Despite the establishment of extensive and successful control programmes in some countries or regions, Echinococcus granulosus still has a very wide geographical distribution. Mature E. granulosus (n = 120) obtained from Parasitology Department, School of Veterinary Medicine, Ferdowsi University of Mashhad (Iran). Soluble protein of whole body of parasite was prepared by freeze-thawing in liqui...

Background: Hydatidosis is a neglected cyclo-zoonotic disease in Middle East countries particularly southeast of Iran which is caused by metacestode of tapeworm Echinococcus granulosus sensu lato. Human hydatidosis is a high public health priority in the area, however there is little known from a phylogenetic perspective on molecular epidemiology of adult Echinococcus spp. in Iranian shepherd d...

Background: Echinococcosis is a zoonotic parasitic disease caused by the larval stage of Echinococcus granulosus. Several native and recombinant antigens, derived from different stages of E. granulosus life cycle, have been used for vaccine trials. In vitro reared adult worms are good candidates for vaccination as they do not produce fertile egg/s and do not have any risk of contamination for r...

PURPOSE Human alveolar (AE) and cystic echinococcosis (CE) caused by the metacestode stages of Echinococcus multilocularis and E. granulosus, respectively, lack pathognomonic clinical signs. Diagnosis therefore relies on the results of imaging and serological studies. The primary goal of this study was to evaluate the efficacy of several easy-to-produce crude or partially purified E. granulosus...
