Cytauxzoonosis in Van cats

Cytauxzoonosis; kedilerin theileriosis’i olarak da bilinen, kedilerde yüksek oranda ölümlere yol açabilen, keneler ile bulaşan ve eritrositer formları ile makrofajlarda doku şizogoni fazına sahip Cytauxzoon felis’in neden olduğu bir protozoon hastalığıdır. Çalışmada 1-7 yaş arasındaki 120 adet Van kedisinde klinik ve hematolojik muayeneler yapıldı. Kedilerde klinik olarak herhangi bir semptoma rastlanmadı. Kan örneklerinden hazırlanan frotilerin mikroskopik muayenesinde 9 (% 7,5) kedide Cytauxzoon felis etkeni belirlendi. Sonuç olarak; Türkiye’de varlığı ilk defa tespit edilen Cytauxzoon felis’e Van kedilerinde %7,5 oranında rastlandı. Ancak kedilerde muhtemelen oluşan preimmünisyon nedeniyle hastalığa ilişkin spesifik semptomlar görülmedi. Bu nedenle, özellikle yaz aylarında kediler sadece mikroskopik olarak değil aynı zamanda serolojik olarak C. felis yönünden incelenmelidir.

Van kedilerinde cytauxzoonosis

Cytauxzoonosis; the disease is known as cat’s theileriosis is a high rate fatal disease transmitted by tick and causes by Cytauxzoon felis, a protozoon, which has shizogony period in both erythrocytes and macrophages. In the present study, the presence of Cytauxzoon felis in Van cats was aimed to investigate. In this study, 120 Van Cats aged between 1-7 and in different sexes were used as materials. For this purpose, routine hematological and biochemical analyses were performed. Clinically, symptoms related to the disease were not observed. Blood smears were also prepared from all cats. Examination of the smears revealed 9 (7.5%) cats had Cytauxzoon felis in their blood. As a result, Cytauxzoon felis which determined first time in Turkey was present at 7.5% ratio. But specific clinical symptoms for the disease were not present possibly due to preimmunity. Therefore, these cats should be examined in terms of Cytauxzoon felis especially during summer season not only microscopically but also serologically.
