Bursa Karacabey Harası’ndaki Atlarda Theileria equi ve Babesia caballi’nin Moleküler Prevalansı

Abstract

Atlarda Theileria equi (T. equi) ve Babesia caballi'nin (B. caballi) neden olduğu at piroplazmozisi (EP) önemli sağlık sorunlarına ve ekonomik kayıplara neden olmaktadır. Epidemiyolojik açıdan önemli olmasına rağmen, Türkiye'de atlarda EP prevalansı hakkında sınırlı bilgi bulunmaktadır. Bu çalışmada harada daimî olarak bulunan ve aşım sezonunda çiftleştirilmek amacı ile Türkiye Jokey Kulübü Karacabey Pansiyon Harası’na getirilen 1518 at dâhil edildi. Atlardan alınan kan örneklerinde, T. equi ve B. caballi’yi tespit etmek amacı ile real-time PCR analizi gerçekleştirildi. Çalışmada, T. equi ve B. caballi etkenlerinin prevalansı %0.59 (9/1518) olarak belirlendi. Çalışmaya dahil edilen atların %0.39’unun sadece T. equi (n= 6), %0.07’sinin ise sadece B. caballi (n= 1) yönünden pozitif olduğu tespit edildi. Ayrıca bu atların %0.13’ü hem T. equi hem de B. caballi (n= 2) yönünden pozitif olduğu belirlendi. Çalışmamızda T. equi’nin moleküler prevalansı %0.53 (8/1518), B. caballi’nin ise %0.19 (3/1518) olarak belirlendi. Ayrıca çalışmada tespit edilen tüm enfekte atlar kısraktı. Çalışmada tespit edilen T. equi ve B. caballi etkenlerine ait moleküler prevalans değerlerinin daha önce Türkiye’de belirlenen moleküler prevalans değerlerinden oldukça düşüktü. Bu çalışmada, Bursa Karacabey Harası’ndaki at popülasyonunda T. equi ve B. caballi etkenlerine ait güncel moleküler prevalans değerleri ortaya konuldu.

Molecular Prevalence of Theileria equi and Babesia caballi in Horses at the Bursa Karacabey Stud Farm

Abstract

Equine piroplasmosis (EP) caused by Theileria equi (T. equi) and Babesia caballi (B. caballi) in horses leads to significant health problems and economic losses. Despite its epidemiological significance, there is limited information available on the prevalence of EP in horses in Turkiye. This study included 1,518 horses that were permanently kept at the stud farm and brought to the Turkiye Jockey Club Bursa Karacabey Pension Stud Farm during the breeding season for mating purposes. Blood samples collected from these horses were analyzed by real-time PCR to detect T. equi and B. caballi. The prevalence of T. equi and B. caballi was determined as 0.59% (9/1518). Findings indicate that 0.39% of the horses included in the study tested positive only for T. equi (n= 6), while 0.07% were positive only for B. caballi (n= 1). Furthermore, 0.13% of these horses tested positive for both T. equi and B. caballi (n= 2). The molecular prevalence of T. equi and B. caballi was 0.53% (8/1518) and 0.19% (3/1518), respectively. All infected horses identified in this study were mares. The molecular prevalence values of T. equi and B. caballi identified in this study were significantly lower than those previously reported in Turkiye. This study revealed the current molecular prevalence of T. equi and B. caballi in the horse population at Bursa Karacabey Stud Farm.
