A Serological invest igation of Enzootic Bovine Leukosis Virus (EBLV) infection in Cattle in Afyonkarahisar Province

Abstract

Bovine Loykoz Virus (BLV) tum dunyada yaygin bir Retroviral enfeksiyondur. Bu calismada, Afyonkarahisar ilinde enzootik form arastirildi. Bu amacla merkezden ve 17 ilceden 6.631 eriskin sigir orneklendi. Sinanpasa, Sandikli, Suhut, Dinar, Cobanlar, Evciler, Hocalar, Sultandagi, Dazkiri, Bayat ve Kiziloren ilcelerindeki kucuk olcekli isletmelerden toplanan 2.275 ornegin tumu ELISA ile negatif bulundu. Pozitiflik belirlenen ilceler ise; Ihsaniye (6/158, %3.79), Bolvadin (5/367, %1.36), Emirdag (9/258, %3.48), Basmakci (2/242, %0.82), Iscehisar (2/177, %1.12) ve Cay’di (1/214, %0.46). Ayrica, 3 buyuk olcekli organize sutcu suru de incelendi. Saglanan 1.915 ornegin 985’inin (%51.43) pozitif oldugu belirlendi fakat 2 suru negatif olarak belirlendi. Sadece birinde %60 pozitiflik belirlendi. Test sonucuna gore, test edilen 6.631 sigirin 1.025’i (%15.45) BLV pozitif olarak belirlendi. Sonuc olarak, enfeksiyon oranlari kucuk olcekli aile tipi isletmelerde oldukca dusuk oldugu hatta bulunmadigi goruldu. Ancak insidensin entansif yetistiricilikte uzun sure yakin temas, danalarin enfekte sutlerle beslenmesi, ayni malzemelerle yapilan enjeksiyon ve asi uygulamalari gibi bulasma yollarina onem verilmemesi gibi nedenlerle oldukca yuksek olabilecegi goruldu. ●●● A Serological investigation of Enzootic Bovine Leukosis Virus (EBLV) infection in Cattle in Afyonkarahisar Province S U M M A R Y Bovine Leukosis Virus (BLV) is a worldwide disseminated Retroviral infection. In this study, Enzootic form was investigated in Afyonkarahisar province. For this purpose, total of 6.631 adult cattle was sampled from both central and 17 borough. The collected 2.275 samples from small scale enterprices in Sinanpasa, Sandikli, Suhut, Dinar, Cobanlar, Evciler, Hocalar, Sultandagi, Dazkiri, Bayat and Kiziloren were found to be negative with ELISA. Positivity determined locations were Ihsaniye (6/158, 3.79%), Bolvadin (5/367, 1.36%), Emirdag (9/258, 3.48%), Basmakci (2/242, 0.82%), Iscehisar (2/177, 1.12%) and Cay (1/214, 0.46%). In addition, 3 big scale organised dairy herds were investigated. Out of 1.915 samples, 985 (51.43%) was determined as positive while 2 herds were negative, while in an only one, 60% positivity was detected. As according to test result, out of tested 6.631 samples, 1.025 (15.45%) was found to be BLV positive. It was concluded that, infection proportions were relatively low or absent in small scale family type farms but incidens could be quite high in intensive breeding due to ignored transmission ways like close contact for a long time, feeding of the calves with infected milk, injections and vaccination applies with same tools.
