Abstract

The current study during the period between thefirst of the September 2014 carrid out end of May 2015 50. birds of  domestic turkey  Meleagrisgallopavowas collested  from different areas of Al- Diwaniya city markets , to isolating and identification  the external and internal parasites parasitized on these birds as well as study the incidence of parasites and intensity and the most important pathological changes and histological changes resulting from external  intestinal infections sex  species of external parasiteswas isolated included four species of biting lice Gonoiocotesgallina , Goniodesgigas , Menacanthusstraminus and Oxylipeurus sp.                                                                                     Theinfection rateand severityof 10%, 6,81,4%, 4,72,2,%, 54.2%, 0.09, respectively, and Two species ofTicksareArguspersicusandHaemophysalissp Nymph.and the severity ofinfectionwas 2%, 0.36; 2%, 0.24: respectively. The  resultsshowedthat  the tripleinfection ofliceare the mostcommon,( 63.63%.) Theinternal parasites9species ofintestinalparasiticwormsin the digestive systemincludedtwo species ofProtozoa Eimeriasp.  andHistomonasmeleagridisTheinfection rate and severitywas14%, 4.200.2%, 0.14, respectively, and 4species oftapeworms Cesticillusrailletina,Tetragonarailletina , Choanoyania infundibulum and HymenolepisspThe severity ofinjurywas2%, 100.2% 53.284, 4,00,2% 2%, 0.42; Respectively, three species  ofnematodesAscardiagallinarum , Capillaria sp. and gallinarumheterakis and  severity ofinjuryandamounted to21.73%, 1.2; 2%0.100; 17.79%, 1.25; .          The study showed the presence of internal parasites  ofwormssitesin the gastrointestinal tractit was observed thatmost oftapewormsparasitizein the small intestineat rateshigher thanwhatis found inother parts ofthe gastrointestinal tract, and the Alaptdaiaatare foundin the liverand small intestine. Thenematodesare also foundin variousparts of thegastrointestinal tract, including bothof the small intestineand thelarge intestineandesophagus. thespecies Haemophysalis sp. and Oxylipeurus sp. and helminthsRaillietinacesticillus ,Raillietinatetragona ,Choanotaniainfundibulum,Hymenolepissp.Ascardiagallinarum ,Capillariasp.Heterakisgallinarum .Eimeriasp first recording in turkeys in Iraq.Also the current study showed a many of gross and  microspcopic pathological changes caused by lice in infected birds, such as lethargy, laziness and sagging wings and nervous tension and break the feathers and hair loss, as well as change the color of the skin.also appeared many of the macroscopic and microscopic changes in the gastrointestinal tract as a result of, intestinal worm included changes macroscopic obstruction and hemorrhagic bruises and blood infiltration The microscopic changes have included the infiltration of inflammatory cells Nicrosis and abstraction  of cells lining the of these channels and the proliferation of Kubffer cells and expansion in  sinosoids and atrophy of the villi tissue.
