Abstract:

Introduction: Protoscolex and hook morphology had been used to identify different strains of Echinococcus granulosus. Method: In the present study, hydatid sand was isolated from infected organs such as liver, lung and spleen from slaughtered animals in several abattoirs in the selected study areas in Libya. Scanning Electron Microscope (SEM) was used to describe the outer surface of the Protoscoleces and the hooks. Result: SEM pictures showed different morphological characters of the outer surface of the different parts of the same protoscolex. Also, the buds on the outer surface of brood capsule, and showed some differences between the large and small hooks. These findings appeared the that there was a correlation with significant statistical difference between the measurements of large as well as small hooks from the same organs of each host as well as between different hosts. Conclusion: Finally, it was difficult to determine whether these cases are not real distortions in the morphology of E. granulosus. They possibly could be caused by mutation or related to a special strain of E.granulosus. Thus, the findings of the present study would suggest that there is a need to consider relationships between the different characters of hooks with different strains of E.granulosus.
