Ege Bölgesi'nde sığırlarda abortusa neden olan dört önemli virus üzerine bir araştırma

Amaç: Çalışmanın amacı, Türkiye'nin Ege Bölgesi'nde 2015-2019 yılları arasında sığır abortus vakalarında Bovine herpesvirus-1 (BHV-1), Schmallenberg virus (SBV), Akabane virus (AKAV) ve pestivirus'ün rolünü araştırmaktır. Gereç ve Yöntem: Bu çalışmada, 2015-2019 yılları arasında Türkiye'nin Ege Bölgesi’nden toplanan 204 aborte fetüs örneği incelenmiştir. Bu amaçla Bovine herpesvirus-1 (BHV-1), Schmallenberg virus (SBV) ve pestivirus taraması için real-time PCR tekniği kullanılırken, Akabane virus (AKAV) için ise nested-PCR tekniği kullanılmıştır. Bulgular: İncelenen örneklerin 25'i (%12.3) pestivirus pozitif, 1'i (%0.5) Akabane pozitif ve 1'i de (%0.5) BHV-1 pozitif bulundu. SBV tespit edilmedi. Bu sonuçlara göre, Ege Bölgesi’nde en fazla aborta neden olan viral etkenin pestivirüs olduğu belirlendi. Laboratuvara en fazla abort materyalinin 2018 yılında gönderildiği, bunu 2019, 2017, 2016 ve 2015 yıllarının takip ettiği belirlendi. Öneri: Bu çalışmanın sonuçlarına dayanarak, Ege bölgesinde tespit ettiğimiz etkenler gelecek değerlendirmelerde dikkate alınmalı, kontrol ve izleme çalışmaları oluşturulmalıdır

Survey of four important viruses causing abortion in cattle in Aegean Region

Aim: The aim of the study was to investigate the role of Bovine herpesvirus-1 (BHV-1), Schmallenberg virus (SBV), , Akabane virus (AKAV) and pestivirus in cattle abortion cases in the Aegean Region of Turkey between 2015 and 2019. Materials and Methods: In this study, 204 bovine abortions that occurred in the Aegean region of Turkey between the years 2015 and 2019 were investigated. While BHV-1, SBV, and pestivirus were examined with real-time PCR, AKAV was examined with nested-PCR. Results: In our study, 25 (12.3%) of the samples analyzed were positive for pestiviruses, 1 (0.5%) was positive for Akabane, and 1 (0.5%) was positive for BHV-1. SBV was not detected. According to these results, the viral agent causing most abortions in the Aegean region was found to be pestivirus. The most abortion-related material was sent to the lab in 2018, followed by 2019, 2017, 2016, and 2015. Conclusion: Based on the results of this study, future evaluations should consider the cattle abortion agents detected in the Aegean region, and control and monitoring studies should be established.
