Özet
Bu çalışma, Mart 1999-Şubat 2000 tarihleri arasında Niğde yöresinde B. ovis'in seroprevalansının araştırılması amacı ile yapılmıştır. Çalışmanın başlangıcında Niğde iline bağlı ve koyunculuğun yoğun olarak yapıldığı Gümüşler, Dikilitaş, Ulukışla, Konaklı, Darboğaz, Kızılca kasabaları, Halaç, Kılavuz, Postallı, Kavuklu köyleri, Ulukışla ve Bor ilçeleri araştırma merkezi olarak seçilmiştir. Çalışma süresince her ay bir merkeze gidilerek rastgele seçilen bir yaş ve üzerindeki 100 koyun belirlenmiş ve bu koyunlar, B. ovis'in varlığı yönünden hem ELISA testi ile serolojik, hem de kan frotilerinde eritrositer form bakımından muayene edilmiştir. Niğde yöresinde muayene edilen toplam 1200 koyunun 645 (%53, 75)'inin B. ovis'e karşı antikor taşıdığı, 297 (%24, 75)'sinde ise B. ovis'in piroplasm formlarının bulunduğu tespit edilmiştir. Serolojik olarak B. ovis'e en fazla Ağustos (%85) ve Eylül (%82), mikroskobik olarak ise en fazla Temmuz (%54) ayında rastlanmıştır. Bu çalışma süresince hayvanların hiçbirinde klinik babesiosis görülmemiştir. Araştırma süresince koyunlar üzerinde toplam 637 adet kene bulunmuştur. Bu keneler %93, 09 (593/637) Rhipicephalus bursa, %4, 23 (27/637) Haemaphysalis punctata, %0, 78 (5/637) Dermacentor niveus, %0, 62 (4/637) Dermacentor marginatus, %0, 62 (4/637) Haemaphysalis inermis, %0, 31 (2/637) Hyalomnıa anatolicum anatolicum, %0, 15 (1/637) Hyalomma anatolicum excavatum ve %0, 15 (1/637) Ixodes ricinus olarak tespit edilmiştir. Sonuç olarak, Niğde yöresinde koyunlarda B. ovis'in serolojik ve mikroskobik incelemelerde yüksek düzeyde bulunduğu saptanmış ancak klinik babesiosis olgusuna rastlanmaması nedeniyle, bölgede B. ovis enfeksiyonunun subklinik seyrettiği üzerinde durulmuştur.
This study was carried out in order to detect the seroprevalence of Babesia ovis in the Nigde Province between March 1999 and February 2000. At the beginning of the study, the villages of Gümüşler, Dikilitaş, Ulukışla, Halac, Kılavuz, Postallı, Konaklı, Darboğaz, Kızılca, Kavuklu and the districts of Ulukışla and Bor were chosen as study sites in the Nigde Province. Each month, one of the study sites was visited once and a total of one hundred sheep one year of age or more, were selected randomly for the study. The sera were separated from the blood and tested for anti-B. ovis antibody using ELISA. The blood smears were examined for B. ovis piroplasms. Out of 1200 sera, 645 (53, 75%) were positive for B. ovis. Examination of the blood smears showed that 297 out of 1200 sheep (24, 75%) were piroplasm carriers. According to the results of sérologie examinations, the rate of B. ovis was highest in August (85%) and September (82%). In addition, the results of microscopic examination showed that the rate was also high in July (54%). None of the animals in the study sites developed clinical babesiosis during the period of this study. Throughout the study, a total of 637 ticks were identified as follows: 93.09% (593/637) Rhipicephalus bursa, 4.23% (27/637) Haemaphysalis punctata, 0.78% (5/637) Dermacentor niveus, 0.62% (4/637) Dermacentor marginatus, 0.62% (4/637) Haemaphysalis inermis, 0.31% (2/637) Hyalomma anatolicum anatolicum, 0.15% (1/637) Hyalomma anatolicum excavatum and 0.15% (1/637) Ixodes ricinus. As a result, subclinical B. ovis infection was detected in sheep in the Nigde Province. A high level of Babesia ovis was determined by the serologic and microscopic examination.
