To investigate bluetongue virus serotype 8 infection in Belgium, we conducted a virologic and serologic survey on 2,416 free-ranging cervids during 2005-2008. Infection emerged in 2006 and spread over the study area in red deer, but not in roe deer.

This study was conducted to determine the seroprevalence of bluetongue virus antibodies in sheep in Kurdistan province in west of Iran during 2011-2012. According to results, the seropositive rates of sheep in Kurdistan were 45.9%. The results showed that in area there is widespread presence of the bluetongue virus antibodies in the sheep population as 123 sheep’s out of 268 were affected.

bluetongue is an infectious disease that primarily affects sheep. but due to serious socioeconomic consequence of it outbreaks on the international trade it has been included in the oie notifiable diseases (list a). during 2007-8, total number of 130 blood samples gathered from suspected sheep to bluetongue disease in seropositive region including khuzestan, kurdistan, fars, ilam and qum provin...

Comparative studies on the detection of bovine serum immunoglobulin G antibodies to bluetongue virus with an enzyme-linked immunosorbent assay, an immunodiffusion method, and a serum neutralization assay demonstrated complete concordance between the enzyme-linked immunosorbent assay and the serum neutralization assay results. However, the immunodiffusion method failed to detect bluetongue virus...

bluetongue (bt) is a viral disease of ruminants transmitted by culicoides biting midges and has the ability to spread rapidly over large distances. the disease occurs almost worldwide between latitudes approximately 35˚ s and 50˚ n. among the numerous diseases of ruminants, bt has gained considerable importance in recent years as one of the best examples of the effects of climate change on dise...

In Germany, bluetongue disease had not been reported before 2006. During August 2006-August 2008, >24,000 bluetongue virus serotype 8 infections were reported, most (20,635) in 2007. In 2006 and 2007, respectively, case-fatality rates were 6.4% and 13.1% for cattle and 37.5% and 41.5% for sheep. Vaccination in 2008 decreased cases.

A novel bluetongue virus termed "Toggenburg Orbivirus" (TOV) was detected in two Swiss goat flocks. This orbivirus was characterized by sequencing of 7 of its 10 viral genome segments. The sequencing data revealed that this virus is likely to represent a new serotype of bluetongue virus [Hofmann, M.A., Renzullo, S., Mader, M., Chaignat, V., Worwa, G., Thuer, B., 2008b. Genetic characterization ...

The objective of this study was to describe the seroprevalence rates of bluetongue virus (BTV) in sheep in west and northwest provinces of Iran. Bluetongue virus, an economically important orbivirus of the Reoviridae family, causes a hemorrhagic disease mainly in sheep and occasionally in cattle and some species of deer. Bluetongue virus is transmitted between its mammalian hosts by ce...

Bluetongue virus (BTV) is an emerging transboundary disease in Europe, which can cause significant production losses among ruminants. The analysis presented here assessed the costs of BTV surveillance and vaccination programmes in Austria and Switzerland between 2007 and 2016. Costs were compared with respect to time, type of programme, geographical area and who was responsible for payment. The...
