With the bluetongue virus serotype 8 (BTV-8) outbreak in 2006, vector monitoring programmes (according to EU regulation 1266/2007) were implemented by European countries to obtain information on the spatial distribution of vectors and the vector-free period. This study investigates the vector monitoring programmes in Austria and Switzerland by performing a retrospective cost analysis for the pe...
BACKGROUND Bluetongue (BT) is a vector-borne disease of ruminants caused by bluetongue virus that is transmitted by biting midges (Culicoides spp.). In 2006, the introduction of BTV serotype 8 (BTV-8) caused a severe epidemic in Western and Central Europe. The principal effective veterinary measure in response to BT was believed to be vaccination accompanied by other measures such as movement r...
AIM The aim of the present study was to carry out antigenic detection of bluetongue virus (BTV) among the small ruminant population of two different geographical regions of Odisha (coastal and central) using recombinant VP7 (r-VP-7) based sandwich enzyme-linked immunosorbent assay (s-ELISA). MATERIALS AND METHODS Blood samples (n=274) were collected from two different geographical pockets of ...
The contemporary circulation of multiple bluetongue virus (BTV) serotypes or strains within the same territory can imply the co-infection of the ruminant and/or the vector populations. As a consequence, the clinical and pathological outcomes of co-infections as well as the biological properties of the viral progeny could be influenced and exhibit relevant variation. In this study, two independe...
Bluetongue virus (BTV) is an economically important Orbivirus transmitted by biting midges to domestic and wild ruminants. The need for new vaccines has been highlighted by the occurrence of repeated outbreaks caused by different BTV serotypes since 1998. The major group-reactive antigen of BTV, VP7, is conserved in the 26 serotypes described so far, and its role in the induction of protective ...
Haemagglutination of bluetongue virus (BTV) was demonstrated for the first time by making use of a purified preparation of the virus. The reaction was found to be independent of variations in the pH, temperature, buffer system and origin of the erythrocytes used in the test. A haemagglutination inhibition test, subsequently developed, was demonstrated to be serotype specific. The storage of the...
