Abstract

Morphological variation in helminthes parasites is a well- established phenomenon and may have many
sources and important taxonomic implications. The morphological differences between the two isolates of
Echinococcus granulosus were the dimensions of worm total length , number of the developing segment ,
testes distribution , details of the cirrus sac and position of genital pore .The results of present study indicate
that there is a form of the parasite is adapted to donkey and other in camel have some differences in
morphological also biological features not tackled in the present work .Genetic study is required for strain
detection for clarification of the situation in a country .
