Comparison of Protoscolex Hook Morphologies in Human, Sheep, Cattle Echinococcus granulosus Isolates

Objective: Cystic echinococcosis (CE) is an important parasitic infection caused by Echinococcus granulosus (E. granulosus) larvae, adults of which live in Canidae. Although CE observed all over the world, it more prevalent developing and underdeveloped nations.
 Material Method: This study was conducted on a total 60 cyst samples, including 20 sheep cattle slaughtered abattoir patients operated with diagnosis KE University Medical Center between dates June 2018 April 2019. The collected fluids were centrifuged protoscolices collected. For each these hosts, large small hooks examined. Large hook length (LHL), (SHL), width (LHW), (SHW), blade (LHBL), (SHBL) measured. measurements made single person, taking into account characteristics specified Hobbs et al. (1990). results evaluated SPSS program.
 Results: average human, bovine LHL 21.710 ± 1.073 μm, 24.322 25.223 μm; SHL 16.946 0.840 20.746 0.911 21.199 0.977 LHW 5.437 0.358 7.817 0.729 8.528 0.589 respectively; SHW 7.229 0.631 6.417 0.507 6.488 0.463 LHBL 13.236 0.746 13.862 0.767 13.345 0.728 SHBL determined as 8.918 0.471 9.414 0.483 9.457 0.476 respectively. length, lengths isolated from significant difference groups. When morphology grouped pairs human-sheep, human-cattle sheep-cattle analyzed statistically; It that LHL, SHL, significantly different but not sheep-cattle. found sheep-cattle, while only human-sheep.
 Conclusion: morphological features E. may represent adaptation vertebrate hosts. this reason, thought parameters can be useful differentiation isolates used together molecular studies future
