Türkiye Jokey Kulübü İstanbul At Hastanesi Laboratuvarına Gönderilen Numunelerdeki Bakteriyel Etkenlerin ve Teşhis Edilen Hastalıkların Dağılımı: Retrospektif Bir Çalışma (2015-2019)

Öz

Türkiye’de damızlık ve yarış atlarında teşhisi yapılmış hastalıkların ve bu atlardan elde edilen bakteriyel etkenlerin sınıflandırılmasına dair kapsamlı bir çalışma bulunmamaktadır. Bu çalışmada, 1 Ocak 2015-31 Aralık 2019 tarihleri arasında, Türkiye Jokey Kulübü (TJK) bünyesinde faaliyet gösteren aşım istasyonu ve hayvan hastanelerine getirilen hasta atlardan alınan numenelerdeki bakteriyel etkenlerin ve bu örneklerin alındığı atlardaki hastalıkların retrospektif olarak dağılımının araştırılması amaçlandı. TJK İstanbul At Hastanesi Laboratuvarı’na en çok gönderilen numunenin trakeal lavaj sıvısı (%47.3) olduğu ve numunelerinin en çok ilkbahar (%33.8) ve sonbahar (%30.8) mevsimlerinde gönderildiği tespit edildi. Gönderilen numunelerin alındığı atlarda en çok solunum sistemi enfeksiyonu (%49.37), daha sonra genital sistem enfeksiyonları (%29.11) ve gastrointestinal sistem enfeksiyonları (%18.57) görüldüğü belirlendi. Gönderilen bütün numunelerde en çok Escherichia coli (%15.6) tespit edildi. Solunum sistemi enfeksiyonlarında, en çok Streptococcus equi subsp. zooepidemicus (%14.53), daha sonra sırasıyla Streptococcus dysgalactiae subsp. equisimilis (%11.11) ve Streptococcus equi subsp. equi (%10.26) identifiye edildiği belirlendi. Sonuç olarak, bu çalışmadan elde edilen bulguların, TJK bünyesinde faaliyet gösteren işletmelerde prevalansı yüksek hastalık veya bakteriyel etkenlere karşı spesifik tedbirlerin alınmasına ve at hastalıklarına bağlı kayıpların minimalize edilmesine katkı sağlaması beklenmektedir.

Distribution of Bacterial Agents and Diagnosed Diseases in Samples Sent to the Jockey Club of Türkiye İstanbul Equine Hospital Laboratory: A Retrospective Study (2015-2019)

Öz

The categorization of diseases identified in Turkish race and breeding horses, as well as the bacterial agents derived from these equines, have not been thoroughly investigated. This study aimed to examine the bacterial agents in samples taken from sick horses brought to the covering stations and animal hospitals operating under the Jockey Club of Türkiye (TJK) between January 1, 2015, and December 31, 2019, and the retrospective distribution of diseases in the horses from which these samples were taken. It was determined that the most frequently sent sample to the TJK İstanbul Equine Hospital Laboratory was tracheal lavage fluid (47.3%) and that the samples were mostly sent in the spring (33.8%) and autumn (30.8%) seasons. It was determined that the most common respiratory system infections (49.37%), followed by genital system infections (29.11%) and gastrointestinal system infections (18.57%) were seen in the horses from which the samples were taken. Escherichia coli (15.6%) was the most commonly detected strain in all submitted samples. In respiratory system infections, the most identified pathogens were Streptococcus equi subsp. zooepidemicus (14.53%), followed by Streptococcus dysgalactiae subsp. equisimilis (11.11%) and Streptococcus equi subsp. equi (10.26%). As a result, it is expected that the findings obtained from this study will contribute to taking specific measures against diseases or bacterial agents with high prevalence in enterprises operating within the TJK and minimizing losses due to horse diseases.
