Abstract :
اجپتينلوزيس (Aegyptianellosis) بيماري ايجاد شده به وسيله اجرام داخل گلبولي (قرمز) بوده که محدود به نواحي از آفريقا، آسيا و جنوب اروپا ميباشد. در اين مطالعه ما شيوع گونههاي اجپتينلا (Aegyptianella spp.) را در چهار جنس از ماکيان را در طول ماههاي فروردين لغايت شهريور 1387 در استان لرستان مورد بررسي قرار داديم. 275 پرنده شامل مرغ، اردک، غاز و بوقلمون که به طور آزاد در طبيعت زندگي ميکردند جهت نمونهبرداري انتخاب گرديدند و خون آنها با تهيه اسمير و رنگآميزي و همچنين بافت شناسي مورد بررسي قرار گرفتند. از 275 پرنده تحت بررسي، 21 مورد (6/7%) به اين انگلهاي خوني آلوده بودند. اين ميکرو ارگانيزمها در 7 مرغ (3/33%)، 2 اردک (5/9%)، 7 غاز (3/33%) و 5 بوقلمون (9/23%) شناسايي گرديد. اين انگلها از نظر فراساختاري به وسيله ميکروسکوپ الکتروني مورد مطالعه قرار گرفتند. پرندگان نواحي جنوب غربي ايران به انگلهاي خوني مبتلا ميباشند که تفاوتها و شباهتهاي درون يا خارج جنسي به کمک ميکروسکوپ الکتروني قابل تمايز ميباشد.
Abstract :
Aegyptianellosis is a disease caused by small intraerythrocytic inclusions which is restricted to the area of Africa, Asia and extreme southern Europe. In this study the prevalence of Aegyptianella spp. was evaluated in four genera of domestic poultry in the northern, southern and central regions of Lorestan province from April to September 2008. A total of 275 native adult birds including chickens, ducks, geese, and turkeys which were bred in free range pasture condition were used for blood sampling in the rural areas of the regions. Twenty one (7.6%) out of 275 birds used in this study were infected with the organisms. The detected Aegyptianella were found in 7 chickens (33.3%), 2 ducks (9.5%), 7 geese (33.3%), and 5 turkeys (23.9%), respectively. The majority of the records were from the northeastern regions. Therefore, more than one-half of the infected birds with the Aegyptianella species were located in these regions. The structure morphology of Aegyptianella spp. was studied using light and electron microscopy. The results of the study by electron microscopy demonstrated the developmental stage as well as implemented similar and different extra/intra genus.
