Molecular Detection and Epidemiological Evaluation of Acute Bee Paralysis Virus in Honey Bees from Isparta, Türkiye

Öz

Acute Bee Paralysis Virus (ABPV) is an important viral pathogen associated with colony losses in bees. This study investigated the presence of ABPV in hives from Isparta, Türkiye, by RT-PCR and statistically evaluated its association with selected epidemiological variables. Samples from 25 apiaries collected in 2025 were subjected to total RNA extraction, cDNA synthesis, and PCR amplification of a 460 bp fragment of the ABPV polyprotein gene. ABPV positivity was 52.0% (13/25; 95% CI: 31.3–72.2). Only colony strength was significantly associated with positivity (p=0.001), with higher odds in weak colonies (OR=36.67). These findings indicate widespread regional circulation of ABPV.

Isparta İlindeki Bal Arılarında Akut Arı Felci Virüsünün Moleküler Tespiti ve Epidemiyolojik Değerlendirmesi

Öz

Akut Arı Felci Virusu (ABPV), bal arılarında koloni zayıflığı ve kayıplarıyla ilişkili önemli bir viral etkendir. Bu çalışmada, Isparta ilindeki bal arılarında ABPV varlığı RT-PCR ile araştırıldı ve seçilmiş epidemiyolojik değişkenlerle ilişkisi istatistiksel olarak değerlendirildi. 2025 yılında 25 gezginci ve sabit arılıktan toplanan örneklerde toplam RNA ekstraksiyonu, cDNA sentezi ve ABPV poliprotein geninin 460 bp’lik bölgesinin amplifikasyonu gerçekleştirildi. ABPV pozitifliği %52.0 (13/25; %95 GA: 31.3–72.2) olarak belirlendi. Yalnızca koloni gücü ile anlamlı ilişki saptandı (p=0.001); zayıf kolonilerde pozitiflik olasılığı daha yüksekti (OR=36.67). Bulgular, ABPV’nin bölgede yaygın olduğunu göstermektedir.
