Necropsy of 65 donkeys in abattoir of Fac. of Vet. Med. Moshtohor and of Giza Zoo during the period from Feb.2007 to Jan. 2008 revealed the presence of 22 helminthes with infection rate (98.45%). The collected worms were Fasciola hepatica, Anoplocephala perfoliata, Hydatid cyst, Parascaris equorum, large Strongylids, small Strongylids, Habronema muscae, H. megastoma, H. microstoma, Setaria equina, Oxyuris equi. Large Strongylids in the present study were identified as Strongylus vulgaris, Strongylus edentatus and Triodontophorus serratus, while small Strongylids were Cylicodontophorus mettami, Cylicostaphanus longibursatus, Cylicostaphanus goldi, Cylicocyclus auriculatus, Cylicocyclus brevicapsulatus, Cylicocyclus insigne, Cyicocyclus labratum, Cyathostomum labiatum, Cyathostomum tetracanthum, Cyathostomum coronatum and Cyathostomum pateratum. All infected donkeys by Fasciola hepatica, hydatid cyst, Parascaris equorum, Setaria equina and Oxyuris equi showed low parasite burden (1-100 worm/ animal). Anoplocephala perfoliata in 60% of infected donkeys of low parasites burden per animals, also 61.11%, 75% and 73.33% of infected donkeys by large Strongylids, small Strongylids and Habronema spp. were found in moderate worm burden (100-500 worm/ animal), respectively. While 86.21% of infected donkeys by Gastrophilus spp. larvae had low burden per animal.Adult ages of autopsied donkeys harbored most of detected parasites except for Habronema spp. which found in older ages. The present data revealed that male donkeys were more susceptible to infection with Fasciola hepatica than females whenever females were more susceptible to hydatid cyst, small Strongylids, Habronema spp., Oxyuris equi and Gastrophilus spp. infection. |
