Abstract:
امتدت الدراسة الحالية من شهر تشرين الاول 2011 ولغاية شهر اذار 2012 , حيث جمعت خلالها 108 نموذجا بواقع 36 عينة من الذكور و72 عينة من الاناث من الدجاج المحلي1758) Gallus gallus domesticus (Linnaeus, من محافظة البصرة بهدف عزل الديدان المتطفلة على القناة الهض | The recent study extended from October 2011 to January 2012, collected 108 samples by 36 samples of males and 72 samples of female of local chickens Gallus gallus domesticus (Linnaeus, 1758)from Basrah to isolate parasitic worms on the gastrointestinal tract and diagnosed as well as study percentage and severity of the infection, as well as monitoring biological activities of isolated parasites and find out macroscopic and pathological changes caused by these worms and find out the impact of tapeworms on the values of the blood parameters of chicken. The results showed infected of chicken with five types of tapeworms (Hymenolepis carioca, Raillietina tetragon, Raillietina cesticillus, Choanotania infundibulum, Cotugina sp) with percent of infection and severity reached 4.62%, 11.4; 19.44%, 12.09; 5.55%, 12.66; 9.25%, 12.6; 6.48 %, 11.14 respectively and got one type of nematodes Subulura brumpti with percentage of infection and severity reached 10.18%, 91 and three types of trematode Echinostoma revulatum, Hypoderm coniodium, Psilolecithum longorchum with percent of infection and severity reached 1.85%, 15.5; 0.92%, 10; 0.92% , 7 respectively.The results of the recent study showed that infection with two types is the most common reaching incidence of 25.92%, and study results indicated that there were significant differences between males and females in susceptibility to intestinal worms.Observed by studying the sites of worms in the gut that the proportion of tapeworms in the small intestine are more than in the large intestine while recorded nematodes only in the large intestine As for worms Trematode has found in the small intestine. The results also included monitoring biological activities of isolated parasites from the gastrointestinal tract from the beginning of the division of the egg and develop into a larva has been observed that the nematodes have the ability to survive outside the host, who were present more than tapeworms.the study contained a physiologic side on the impact of tapeworms on some blood parameters where showed infection of domestic fowl with anemia by observing the decrease in the number of red blood cells R.BC , hemoglobin Hb and P. CV while there was an increase in the number of white blood cells WBC. The study recorded the number of grossly and histological lesions in the intestine and the cecum of domestic chicken Because they infected with tapeworms, nematodes and flukes. grossly lesions included blockage and swelling in the intestines infected with tapeworm and cecum infected with nematode and appearance of rough nodules on the walls of the intestine infected with tapeworm with hemorrhage and the appearance of yellowish green purulent material in the inner wall of the intestines, and the histological changes has included atrophy of intestinal villi with sloughing and desquamation of epithelial layer with appearance of inflammation in the form of pseudomembrane and infiltration of inflammatory cells and coaglative necrosis, it have seen hemorrhage and superficial erosion in the mucous layer and sloughing of villi and epithelial layer with hyperplasia appearance purulent cells and destruction of intestinal glands and ulceration in the mucous layer in addition to the congestion
