Abstract:
صممت الدراسة الحالية لمعرفة التغيرات الدموية والكيموحيوية والنسجية الناجمة عن الاصابة التجريبية بالقمل العاض Biting lice وكذلك لاثبات دور القمل في نقل طفيلي المقوسة الكوندية Toxoplasma gondiiمن الطيور المصابة الى الطيور السليمة للمدة من الاول من شهر تشرين | The current study was designed to showed the haematological, biochemical and histological changes caused by experimentally infection with biting lice, as well as to prove the role of lice in the transmission of Toxoplasma gondii parasite from infected to healthy birds for the period from November 2013 to June 2014. 30 bird were taken from the chickens local chicks Gallus gallus domesticus aged one week purchased from local markets of AL - Diwaniya city divided into three groups included of each 10 birds (two experimentally groups and one control group) it was hit by lice from naturally infected chickens and then measured blood, biochemical parameters and histological changes at the end of experiment about seven months. Then we collected 30 bird from adult local chickens Gallus gallus domestics at age greater than 4 months and infected with dense lice from markets of AL - Diwaniya city, All samples tested by serological test using Latex Agglutination Test to detects of Toxolasma gondii parasite, 17 samples were positive for Toxoplasma gondii parasite with percentage 56.66% and the highest proportion in the birds recorded at the standard 1/80 (41.17%) and the lowest proportion at standard 1/40, 1/640 reached (5.88%) for both. Four species of biting lice isolation after end of the experiment include, Menacanthus stramineus, Menacanthus cornutus, Menopon gallinae and Goniocotes gallinae at infected percentage 53.59%, 17.37%, 22.57%, 6.45% respectively. Results showed the blood parameters at end of the experiment significantly decreased in the number of red blood cells2.29(x106/mm3), packed cell volume 37.99%, Haemoglobin 9.52(g/dl) and Mean corpuscular Haemoglobin concentration 29.09(g/dl) while showed significantly increased in Mean corpuscular volume 143.23(µ/m3), Mean corpuscular Haemoglobin 47.32(pg) and blood platelets24.36(x103/mm3), and the results showed significantly increased in white blood cells count144.05(x103/mm3), percentageMonocytes 9.10%, Eosinophils4.82%, Neutrophils2.80% and significantly decreased in percentage Lymphocytes67.43%. The results showed biochemical parameters significantly decreased Glucose and Cholesterol concentration and significantly increased in uric acid and Total protein concentration and non - significantly increased in creatinin concentration. The pathological changes caused by infection in two group experiment showed abnormal behavioral changes in infected birds with lice such as instability, constant irritability as well as tweezing and the frequent use of the beak, legs and moving the wings as well as the lack of eating and decrease of weight. The results also show the occurrence pathological gross changes in the birds represented by molt of feather and appearance nacked areas free of feather as well as redness and inflammation of the areas of the skin as a result of wounds and scratches and haemorrhage as well as incidence of histological changes in each of (skin, muscle, liver, kidney, spleen, small intestine and lungs) represented by proliferation fibrous connective tissue in layer of the dermis and infiltration of inflammatory cells as well as hyperplasia in epithelial layer of the epidermis also appeared degeneration and necrosis of the muscle fibers where appeared free nuclei with infiltration of inflammatory cells out of the blood vessels in addition to the appearance bleeding within the muscle fibers in the liver there appeared congestion of central veins with loss of the geometric structure of the liver tissue and infiltration of inflammatory cells near the central vein with fatty degeneration of the liver cells as happened atrophy of the intestinal villi and crashing and alienation in the villi that lining the vertical cells. in the kidney, noted presence of severe bleeding in the renal tissue and necrosis of the cell lining of renal tubules twisted with atrophy of the renal glomeruli. in the spleen, the results showed atrophy an exhausted pulp white with severe proliferation in red pulp and incidence of hemorrhage and necrosis widely in the lymphoid tissue of the spleen. also the air sacs appeared in lungs full of red blood cells with a large clot inside a blood vessel. Finally, according to the results of molecular analysis of tissue of biting lice from species Menacanthus stramineus using conventional polymerase chain reaction PCR to the emergence of gene diagnostic B1(399bp) specific Toxoplasma gondii parasite in 12 sample of the total samples tested, about 22 samples percentage 54.54% which indicates presence of the parasite and the lice ability to transfer parasite within his body parts
