This study was carried out to determine the prevalence of ovine Sarcocystis species in Izmir province. A total of 734 muscle samples of 200 sheep from four different age groups were surveyed by the digestion and histological examination methods for the presence of Sarcocystis species. Sarcocystis ovifelis, Sarcocystis ovicanis, and Sarcocystis arieticanis were detected as the responsible species for ovine sarcosporidiosis in Izmir province. Macrocysts of S.ovifelis were found in 24.5 % (49/200) of sheep and the highest prevalence was detected in the oesophagus in all age groups. Microcysts of S.ovicanis and S.arieticanis were present in 86.5 % (173/200) of sheep. The prevalence of Sarcocystis cysts increased significantly with the age. Although microcysts were detected in 46 % (23/50) of lambs up to 6 months of age, they were present in all muscle samples of sheep (150/150) over 6 months of age. Histologically, no inflammatory reaction was seen against sarcocysts within the infected muscles, unless they degenerated. There was no significant difference (p>0.05) statistically between sensitivities of two diagnostic methods (digestion and histology) in detecting Sarcocystis species. These results reveal the fact that the environment is heavily contaminated with sporocysts, and the ingestion of sporocysts by sheep begins from the young ages in Izmir province

Bu çalışma, İzmir ilinde koyun Sarcocystis türlerinin yayılışını belirlemek amacıyla yapıldı. Bu amaçla dört farklı yaş grubundan 200 koyuna ait toplam 734 kas örneği, Sarcocystis türlerinin varlığı yönünden enzim tekniği ve histolojik muayene metodları ile araştırıldı. İzmir ilindeki koyunlarda sarcosporidiosis’den sorumlu türler, S.ovifelis, S.ovicanis ve S.arieticanis olarak tespit edildi. S.ovifelis makrokistleri, koyunların % 24,5 (49/200)'inde bulundu ve tüm yaş grublarında en yüksek prevalans ösefagusta tespit edildi. S.ovicanis ve S.arieticanis mikrokistleri, koyunların % 86,5 (173/200)’inde mevcuttu. Sarcocystis kistlerinin prevalansı, yaş ile önemli derecede arttı. Mikrokistler, 6 aylığa kadar olan kuzuların % 46 (23/50)’sında bulunduğu halde, 6 aylıktan büyük koyunların tüm kas örneklerinde mevcuttu. Histolojik olarak, kistler dejenere olmadıkça, enfekte kas tellerindeki sarkokistlere karşı yangısal bir reaksiyon görülmedi. Sarcocystis türlerinin tespitinde, iki teşhis metodunun (enzim tekniği ve histoloji) duyarlılıkları arasında istatistiksel olarak önemli bir fark (p>0,05) bulunmadı. Bu sonuçlar, İzmir ilinde çevrenin sporokistler ile yoğun şekilde kontamine olduğu ve koyunlar tarafından sporokist alımının genç yaşlardan itibaren başladığı gerçeğini ortaya koymaktadır
