Seroprevalence of Schmallenberg Virus Antibodies among Dairy Cattle, the Netherlands, Winter 2011–2012
نویسندگان
چکیده
Infections with Schmallenberg virus (SBV) are associated with congenital malformations in ruminants. Because reporting of suspected cases only could underestimate the true rate of infection, we conducted a seroprevalence study in the Netherlands to detect past exposure to SBV among dairy cattle. A total of 1,123 serum samples collected from cattle during November 2011-January 2012 were tested for antibodies against SBV by using a virus neutralization test; seroprevalence was 72.5%. Seroprevalence was significantly higher in the central-eastern part of the Netherlands than in the northern and southern regions (p<0.001). In addition, high (70%-100%) within-herd seroprevalence was observed in 2 SBV-infected dairy herds and 2 SBV-infected sheep herds. No significant differences were found in age-specific prevalence of antibodies against SBV, which is an indication that SBV is newly arrived in the country.

BACKGROUND Schmallenberg virus (SBV) emerged in northern-Europe in 2011 resulting in an epidemic of ruminant abortions and congenital malformations throughout the continent. In the years following the epidemic there have been reports of SBV overwintering and continued circulation in several European countries. When the population-level of immunity declines in exposed regions, re-introduction of...
متن کاملComparative prevalence of Bovine Viral Diarrhea Virus antibodies among native and imported cattle in north of Sistan and Baluchistan- Iran
Background and Aims: Sistan is a major pole in dairy production and genetic resource for the unique sistanian breed in the southeast of Iran. This region has a wide border with Afghanistan and cattle imports are done through this border. The main aim of this study was to compare the seroprevalence of Bovine Viral Diarrhea Virus (BVDV) infection rate using direct Enzyme-linked ...
متن کاملEpizootic Spread of Schmallenberg Virus among Wild Cervids, Belgium, Fall 2011
Schmallenberg virus was detected in cattle and sheep in northwestern Europe in 2011. To determine whether wild ruminants are also susceptible, we measured antibody seroprevalence in cervids (roe deer and red deer) in Belgium in 2010 and 2011. Findings indicated rapid spread among these deer since virus emergence ≈250 km away.
متن کاملA Serological Study on Bovine Leukemia Virus Infection in Ten Provinces of Iran between 2010 and 2012
Background and Aims: Bovine leukaemia virus (BLV) is an oncogenic member of the genus Deltaretrovirus of the family Retroviridae. BLV is the causative agent of enzootic bovine leukaemia and infects cattle worldwide, imposing economic impact on the dairy cattle industry. The purpose of this study was to estimate the seroprevalence of BLV in cattle in some provinces of Iran. Materials and Methods...
متن کاملTransmission of Schmallenberg virus in a housed dairy herd in the UK
Schmallenberg virus (SBV) is a recently emerged Orthobunyavirus of ruminants originally discovered in 2011 near the town of Schmallenberg in Germany (Hoffmann and others 2012). SBV appears to have entered Europe in the summer of 2011 and has since spread rapidly across much of central and northern Europe. Seroprevalence in some areas has been reported close to 100 per cent (Tarlinton and others...
