“…However, acute CCHF cases have never been diagnosed among humans in Darfur region of the Sudan. This is probably attributed to the fact that (Aradaib et al, 1998(Aradaib et al, , 2005(Aradaib et al, , 2010. Previous CCHF studies in humans showed prevalence rate of 13.1% among nomadic tribes in Senegal (Chapman et al, 1991).…”

“…BTV causes clinical disease predominantly in sheep, whereas cattle act as reservoir hosts and play an important role in the transmission to Culicoides and in the epidemiology of BT because they show prolonged viraemia (4). The subclinical infection in cattle may be associated with reduced milk yield, infertility, teratogenesis and abortion (5,6). In Nepal, BTV infection was first reported in sheep in 2008 (7) and subsequent studies revealed that 5-28.4% of the sheep from 11 districts were seropositive to BTV (8).…”

Cattle play an important role in the epidemiology of bluetongue (BT) by acting as reservoir hosts. However, the status of BT virus (BTV) in dairy cattle in Nepal is unknown. The objective of this study was to estimate the prevalence of BTV antibodies in dairy cattle in two eco-zones of Nepal, and to identify the factors associated with virus exposure. The authors conducted a cross-sectional serosurvey from March 2012 through February 2013 by sampling 131 dairy cattle from seven clusters (villages) in the Chitwan district in the Terai region (southern lowlands) and the Lamjung district in the Hills region (the middle part of Nepal). Of the 131 serum samples tested, 29.3% (95% confidence interval [CI]: 21.5-37.2) were positive for BTV antibodies. Herd-level seroprevalence was 45.7% (95% CI: 30.9-61.0). Bivariate analysis indicated a positive association between seroconversion to BTV and age, and an association with breed of cattle after controlling for clustering of animals within herds. Based on this model, cattle were more likely to become seropositive as they aged. Crossbred cattle were more likely to be seropositive than those of exotic breeds (odds ratio [OR] = 4.6; 95% CI: 1.5-14.1). The results indicate widespread exposure of dairy cattle to BTV in Nepal. The authors suggest that dairy cattle should be included in the surveillance plan for BTV infection in Nepal and that it is important to educate farmers about the possible impacts of this disease.

“…Bluetongue is an important and abortive infection of both domestic (Sheep, goat, camels, etc) and wild ruminants which clinical characterized by different symptoms such as congestion, cyanosis of the tongue, hemorrhage near the base of the pulmonary artery, oedema, reduced wool quality, poor subsequent reproductive performance, decrease milk production (Verwoerd and Erasmus 2004, Aradaib et al 2005, Gür 2008, Maclachlan et al 2008. BTV infection is a seasonal infection (Carpenter et al 2013) and may cause economic losses (van der Sluijs et al 2012) in flocks and transmitted by Culicoides species; therefore, the prevalence of the BTV infection increases during the spring, summer, and fall when the density of Culicoides increases (Tabachnick 1996, Meiswinkel et al 2008, Darpel et al 2011, van der Sluijs et al 2012.…”

Karaman ilinde yetiştirilen koyunlarda Blue Tongue Virus enfeksiyonunun serolojik olarak araştırılması Öz Amaç: Bu çalışma Karaman'da bulunan koyun işletmelerinde Blue Tongue Virus'a karşı seroprevalansın belirlenmesi amacı ile yapıldı. Gereç ve Yöntem: Beş farklı işletmeden rastgele seçilen (her birinden 70 adet) toplam 350 koyundan kan serum örnekleri toplandı. Örnekler Blue Tongue Virus'a karşı gelişen antikor varlığı yönünden ticari olarak temin edilen competitive enzyme linked immunosorbent assay (cELISA) ile test edildi. Bulgular: İşletmelerde Blue Tongue Virus'a karşı gelişen antikor prevalansı sırası ile %32.85, %28.57, %25.71, %37.14 ve %41.42 olarak belirlendi. Toplam 350 serum örneğinin 116 (%33.14)'sı Blue Tongue Virus'a spesifik antikor varlığı yönünden cELISA ile pozitif tespit edildi. Öneri: Türkiye'nin iklim şartları Blue Tongue Virus'un vek-tör Culicoides türlerinin yaşamları için uygun olduğundan, koyunlar Blue Tongue Virus yönünden sürekli kontrol edilmelidir.
