BTV antibody longevity in cattle five to eight years post BTV-8 vaccination

Vaccine, 2019
The Bluetongue virus serotype -8 (BTV-8) epizootic in Germany (2006-2008) was successfully eradicated, essentially by the massive application of commercially available inactivated BTV-8 vaccines. While a six-year antibody longevity of BTV antibodies post BTV-8 vaccination in cattle has been described previously, our study investigated the BTV-8-vaccine

Bluetongue Virus: From BTV-1 to BTV-27

Adv Virus Res ., 2017
Bluetongue virus (BTV) is the type species of genus Orbivirus within family Reoviridae. Bluetongue virus is transmitted between its ruminant hosts by the bite of Culicoides spp. midges. Severe BT cases are characterized by symptoms including hemorrhagic fever, particularly in sheep, loss of productivity, and death.

Emergence of Bluetongue Serotypes in Europe, Part 1: Description and Validation of Four Real-Time RT-PCR Assays for the Serotyping of Bluetongue Viruses BTV-1, BTV-6, BTV-8 and BTV-11

Transboundary and Emerging Diseases, 2009
The control of bluetongue virus (BTV) in Central-Western Europe is greatly complicated by the coexistence of several BTV serotypes. Rapid, sensitive and specific assays are therefore needed to correctly identify the currently circulating BTV serotypes in field samples.

IgE responses to bluetongue virus (BTV) serotype 11 after immunization with inactivated BTV and challenge infection

Comparative Immunology, Microbiology and Infectious Diseases, 1999
To test the hypothesis that development of a BTV-specific IgE response plays a role in clinical disease manifestation, the humoral immune response of cattle to inactivated and virulent BTV was studied. Three calves received three sensitizing immunizations of inactivated BTV, 3 weeks apart. The BTV-sensitized animals, two non-sensitized BTV-seropositive

Predicting BTV incursions

Veterinary Record, 2009
The Rooker prize, which recognises outstanding contributions to veterinary science through research into the understanding, prevention or treatment of livestock diseases, was presented for the first time at this year's Veterinary Laboratories Agency conference, held at the Royal Holloway College, University of London, from September 2 to 4.

Full genome sequence of the first bluetongue virus serotype 21 (BTV-21) isolated from China: evidence for genetic reassortment between BTV-21 and bluetongue virus serotype 16 (BTV-16)

Archives of Virology, 2018
Bluetongue (BT) is one of the most important insect-borne, non-contagious viral diseases of ruminants and can cause severe disease and death in sheep. Its pathogen, bluetongue virus (BTV) has a double-stranded RNA genome consisting of 10 segments that provides an opportunity for field and vaccine strains of different serotypes to reassort whilst ...

Assessment of efficacy of a bivalent BTV-2 and BTV-4 inactivated vaccine by vaccination and challenge in cattle

open access: yesVeterinary Microbiology, 2009
The efficacy of a bivalent inactivated vaccine against bluetongue virus (BTV) serotypes 2 (BTV-2) and 4 (BTV-4) was evaluated in cattle by general and local examination, serological follow-up, and challenge. Thirty-two 4-month-old calves were randomly allocated into 2 groups of 16 animals each.

Transplacental transmission of BTV-8 in sheep: BTV viraemia, antibody responses and vaccine efficacy in lambs infected in utero

Vaccine, 2013
Bluetongue virus (BTV) is an insect vector transmitted virus which causes an economically important disease in ruminants. BTV infection during pregnancy can result in infection of the foetus, which may lead to the birth of persistently infected or immunotolerant offspring.

Bluetongue Virus (BTV): Propagation, Quantification, and Storage

Current Protocols in Microbiology, 2012
AbstractAs an obligate intracellular parasite, the genome of the Bluetongue virus (BTV) contains ten double‐stranded RNA segments which are encapsidated by viral proteins, forming “transport vesicles” that can transmit the viral progeny cell‐to‐cell efficiently and that can also be transmitted animal‐to‐animal by a biting midge.
