Prevalence and pathologic study of Eimeria cameli in slaughtered camels

Amaç: Araştırmanın amacı mezbahada kesime tabi tutulan develerde Eimeria enfeksiyonunun varlığını araştırmak ve gastrointestinal kanalda histopatalojik lezyonlarını tanımlamaktır. Gereç ve Yöntem: Kesilen 100 adet (68 erkek, 32 dişi, 6 ay - 8 yıl) deveye ait barsaklar Eimeria varlığı için mikroskopik olarak incelendi. Develer yaş (4 yıl) ve cinsiyet (erkek, dişi) olarak 3 gruba ayrıldı. Eimeria spp. prevalansı ve gaitada ookist varlığı flotasyon ve sporulasyon teknikleri ile belirlendi. İntestinal kanaldan alınan doku örnekleri %10 formalinde sabitlendi. Örnekler parafine gömüldükten sonra 5 μm kalınlıkta kesilerek Hematoxylin- Eosin ile boyandı. Bulgular: Araştırılan 100 devenin 29 (%29)’unda Eimeria cameli tespit. Develerde cinsiyet ve yaş grupları arasında hastalığın prevalansı açısından fark belirlenmedi (p>0.05). Mikroskopik incelemede eozinofilik enterit ve Lieberkuhn bezinin epiteli ile lamina propriada giant sizont, mikrogamet, makrogamet ve ookistler belirlendi. Öneri: Eimeria cameli enfeksiyonlarının İran’ın güney doğusunda yaygın olduğu ve kontrol programları düşünüldüğünde enfeksiyon varlığının değerlendirilmesinin faydalı olacağı ifade edilebilir.

Kesime tabi tutulan develerde Eimeria cameli prevalansı ve patolojik araştırması.

Aim: This study was carried out to determine Eimeria infection in slaughtered camel and describe the gross and histopathologic lesions caused by Eimeria species in the intestinal tract. Materials and Methods: Slaughtered 100 camels (68 males, 32 females, 6 months to 8 years, Kerman) were investigated for the presence of Eimeria parasites microscopically in intestinal tracts. Camels were classified into 3 groups according to the age (4 years) and sex (male, female). The prevalence of Eimeria spp. infection and the intensity of faecal oocysts were determined using floatation and sporulation techniques. Tissue samples were taken from the intestinal tracts and then fixed in 10% buffered formalin. They were processed and embedded in paraffin. Sections of 5 μm thickness were cut and stained with Hematoxylin and Eosin. Results: Eimeria cameli were found in 29 (29%) of the 100 camels. Sex and age of camels did not have significant (p>0.05) effect on prevalence. Microscopic examination revealed eosinophilic enteritis and existence of developmental stages of the parasite such as giant schizonts, microgamont, macrogametocytes, and oocysts in the lacteals of lamina propria and in the epithelium of Lieberkuhn glands. Conclusion: Eimeria cameli infection is prevalent in camels in the south-eastern part of Iran and the evaluation of infection potential can be useful when considering control programs.
