Seroepidemiological studies of equine herpesviruses 1 (EHV-1) and 4 (EHV-4) infections in working horses from the eastern Turkey

Bu araştırmada, Türkiye'nin Doğu Anadolu bölgesinde yer alan 5 ilde kullanılan lokal ırk atlarda, at herpesvirus tip-1 (EHV-1) ve 4 (EHV-4)'e karşı oluşmuş antikorların varlığının belirlenmesi amaçlandı. Van, Bitlis, Muş, Erzurum ve Iğdır illerindeki aşılanmamış toplam 405 attan toplanan kan örnekleri ticari bir ELISA kiti ile test edildi. Test edilen serumların, 94 adedi (%23.2) EHV-1; 316 adedi ise (%78) EHV-4 antikorları yönünden pozitif bulundu. İllere göre EHV-1 seropozitiflik oranları; Van'da %29.5, Bitlis'te %6.1, Muş'ta %5.1, Iğdır'da %24 ve Erzurum'da %20.6 olarak tespit edilirken, EHV-4 için seropozitiflik oranları; Van'da %87.2, Bitlis'te %61.2, Muş'ta %56.4, Iğdır'da %84 ve Erzurum'da %52.9 olarak saptandı. Bu araştırma, EHV-1 ve EHV-4 infeksiyonlarının Doğu Anadolu bölgesine ait 5 ildeki lokal at populasyonlarında oldukça yaygın olduğunu ortaya koymuştur. Ayrıca, Türkiye'nin doğu sınırında yer alan iki ilde (Van ve Iğdır) her iki infeksiyona karşı belirlenen yüksek seropozitifliğin, gelecekte birçok önemli hastalığın sınır ticareti yolu ile ülkemize girişine yönelik risk oluşturabileceği sonucuna da varılmıştır.

Türkiye'nin Doğu illerindeki yük atlarında at herpesvirus 1 (EHV-1) ve 4 (EHV-4) infeksiyonlarının seroepidemiyolojisi

The objective of this research was to determine the presence of equine herpesvirus types 1 (EHV-1) and 4 (EHV- 4) antibodies in local horses from five provinces in the East Anatolia region of Turkey. Blood samples were collected from 405 nonvaccinated horses living in Van, Bitlis, Muş, Erzurum, and Iğdır, and were analyzed via a commercial enzyme-linked immunosorbent assay (ELISA). EHV-1- and EHV-4-specific antibodies were detected in 94 (23.2%) and 316 (78.0%) of the 405 tested sera, respectively. The seropositivity percentages for EHV-1-specific antibodies by province were as follows: 29.5% in Van, 6.1% in Bitlis, 5.1% in Muş, 24.0% in Iğdır, and 20.6% in Erzurum. EHV-4-specific antibodies were detected at levels of 87.2% in Van, 61.2% in Bitlis, 56.4% in Muş, 84.0% in Iğdır, and 52.9% in Erzurum. The present investigation demonstrated that EHV-1 and EHV- 4 infections were more prevalent in the indigenous horse population from five provinces in the East Anatolia region of Turkey. Also, this data on the high seropositivity of both infections in two provinces (Van and Iğdır) along the eastern border of Turkey may be also serve as a risk indicator for future introductions of some transboundary diseases via border trade.
