Studies On The Helminth Parasites Infesting Aquatic Egyptian And Migrant Birds

The survey(39 migratory of helminthes in 172 aquaticduoks, 87 domestic duoks and 46 birds domestic geese) from Sharkia Governoratc revealedthat the incidence of infestation was 89.7%~ 31% and 56.5% respeotively.Fourteen species of helminthes were oollect-ed from migratory ducks: Psilochasmus sp ..spelophallus!sp..echinostoma revolutum, notocotylus spp., echino- bulbode.s, Retinometers~acrocaqt4oE. Dipopotps laevis, Amidost_olcutum.caEillar:i”.a anat.i.f1.and C,a.pi1lux:i,a obsi&na.t.E!.The parasites which were collected tromdomestic ducks and geese were: One species of trematoda(~cotcestodaobolevicanthus gracilisin ducks only) and twospecies of nematoda. (heterakis dispar and capillaria obsignata psigna~a).The seasonal dynamics of helminth parasitesin migratory ducks showed that all the migratory duckswhich were examined during December and March were all
