Türkiye’de Campylobacter fetus subsp. fetus ST2 İlişkili Koyun Abortusu

Bu çalışmada, 200 başlık bir koyun sürüsünde görülen abortus olgularının mikrobiyolojik, moleküler ve patolojik bulgularının değerlendirilmesi amaçlandı. Aborte fetuslarda makroskopik olarak karaciğerde düzensiz nekrotik odaklar gözlendi. Etken izolasyonu için seçici ve seçici olmayan besiyerleri kullanıldı. İdentifikasyonda fenotipik ve moleküler testlerden yararlanıldı. Atık dört fötüsun organlarından Campylobacter fetus subsp. fetus (Cff) izole edildi. Abort yapmayan koyunlardan alınan vajinal swap, su, yem ve altlık örnekleri Cff yönünden negatif bulunurken, abort yapan 20 koyunun dışkı örneklerinin 5’i ve vajinal swap örneklerinin 5’i Cff pozitif olarak saptandı. Genotiplendirmede Multilokus Sekans Tiplendirme (MLST)’den yararlanıldı ve tüm izolatların ST2 (Sekans Tip 2) olduğu belirlendi. Bu çalışma, Türkiye’de koyunlarda abort olgularından Campylobacter fetus subsp. fetus ST2’nin bildirildiği ilk rapordur. Yurdumuzda abort olgularından izole edilen Campylobacter türlerini içeren aşıların geliştirilmesi ve kullanımının, Campylobacter fetus subsp. fetus’un da neden olduğu abortusların hem profilaksisine hem de kontrolüne katkıda bulunacağı düşünülmektedir.

Ovine Abortion Associated with Campylobacter fetus subsp. fetus ST2 in Turkey

In this study, we aimed to evaluate the microbiological, molecular and pathological findings of abortus cases detected in a sheep herd consist of 200 animals. Macroscopically, irregular necrotic foci were observed in the liver in aborted fetuses. Selective and non-selective media were used for the isolation of causative agent. Phenotypic and molecular tests were performed for identification. Campylobacter fetus subsp. fetus (Cff) was isolated from organs of four foetuses aborted. While the vaginal swap samples taken from sheep that did not abort, water, feed and litter samples produced negative results for Cff, 5 of the 20 faecal samples and 5 of the vaginal swaps taken from the sheep that had aborted, yielded Cff. Multilocus Sequence Typing (MLST) was used for genotyping and all isolates were detected as Sequence Type 2 (ST2). This is the first documented report of an ovine abortion caused by Cff ST2 in Turkey. It is considered that the development and use of vaccines, containing local Campylobacter species, would contribute to both prophylaxis and control of abortions caused by campylobacters including Campylobacter fetus subsp. fetus.
