Soluble Antigen of Blue-Tongue Virus

Soluble antigen of blue-tongue virus.

A soluble viral antigen with possible diagnostic utility was obtained from blue-tongue virus-infected lamb kidney cells. It is a noninfectious proteinaceous substance without nucleic acid. The antigen is immunologically identical to one component of the viral particle, and in agar-gel diffusion tests it reacted with antiserum against several blue-tongue virus strains.

Preparation and characterization of a soluble precipitating antigen from African horsesickness virus propagated in cell cultures

La Crosse virus soluble cell culture antigen.

A virus-free soluble antigen, obtained by ammonium sulfate precipitation of the supernatant fluids of La Crosse virus-infected BHK-21 cell cultures, was more reactive and more specific than infected suckling mouse brain antigen when compared by immunodiffusion and counterelectrophoresis tests. By complement fixation tests, the antigen was cross-reactive with heterologous California group arbovi...

Detection of Antibodies against Blue Tongue Virus in Yaks (bos Grunniens) in Issyk Kul, First Report

Bluetongue virus (BTV) caused infection is commonly determined in ruminants including sheep and cattle. However, there is a little information about the seroprevalence of BTV in yaks. The aim of this study was to describe the seroprevalence rate BTV in unvaccinated yaks in Issyk Kul, Kyrgyzstan. A total of 168 serum samples were collected from yaks between September to November 2012. Antibodies...
