Serological Survey of Bluetongue Virus Serotype-8 Infection in South American Camelids in Switzerland (2007-2008)

Serological Survey of Bluetongue Virus Serotype-8 Infect ion in South American Camelids

Background: Outbreak of bluetongue virus serotype-8 (BTV-8) infection in domestic ruminants in Northern Europe. Objective: To investigate the South American camelids’ (SAC) susceptibility to BTV-8 infection, their role in the epidemiology of the disease, and the use of currently available serological screening tests in SAC in an endemic region. Animals: Three hundred and fifty-four unvaccinated...

Bluetongue Virus Serotype 8 Reemergence in Germany, 2007 and 2008

Reemerging bluetongue virus serotype 8 (BTV-8) in Germany was detected first in May 2007 in a sentinel cow and in February 2008 in an export heifer. Reemergence was confirmed by retesting the samples, experimental inoculation, fingerprinting analysis, and virus isolation. Overwintering of BTV-8 and continuous low-level infections are assumed.

Anatomy of Bluetongue virus Serotype 8 Epizootic Wave, France, 2007–2008

The introduction of bluetongue virus serotype 8 into northern Europe at the end of summer 2006 initiated one of the most widespread epizootics of bluetongue infection ever to occur. In winter 2007-2008, a cross-sectional serologic study was conducted in France along a transect perpendicular to the epizootic wave. Cattle herd-level seroprevalence varied from 4% to 100%, and animal-level seroprev...

Epidemiological study of pestiviruses in South American camelids in Switzerland.

BACKGROUND In the context of the ongoing eradication campaign for bovine viral diarrhea virus (BVDV) in cattle in Switzerland, the role of South American camelids (SAC) as a possible virus reservoir needed to be evaluated. OBJECTIVE To assess and characterize the prevalence of pestivirus infections in SAC in Switzerland. ANIMALS Serum samples collected from 348 animals (40 herds) in 2008 an...
