Development of plant-produced Bluetongue virus vaccines
Bluetongue is a disease of domestic and wild ruminants caused by Bluetongue virus (BTV). It has caused several serious outbreaks, the most recent occurring in Northern Europe in 2006 during which high mortality rates of livestock were reported. The only vaccines currently approved and commercially …

Reassortment of bluetongue virus vaccine serotypes in cattle
Bluetongue (BT) is a non-contagious viral disease of domestic and wild ruminants. Bluetongue virus (BTV), an Orbivirus that belongs to the family Reoviridae, is the causing agent of the disease. The virus consists of a ten segmented double stranded (ds) RNA genome and currently 27 serotypes have …

The molecular epidemiology of bluetongue virus in northern Colorado
… years of study, the overwintering mechanism of bluetongue virus (BTV) has never been elucidated to a scientifically satisfactory degree. This is an important area of research because current trade agreements between the United States and its partners allow for the regionalization of disease …

Investigation of particulate Bluetongue virus vaccines made in plants
Bluetongue virus (BTV) infects ruminants but predominantly causes severe and often fatal haemorrhagic fever, known as Bluetongue (BT) disease, in sheep. Increasing global temperatures have contributed to the global dissemination of BTV. This is a result of the Culicoides insect vectors which …

Vertical transmission in the culicoid vector as a possible mechanism for bluetongue virus transeasonality
Bluetongue virus (BTV) is transmitted between vertebrate hosts by arthropod vectors in the genus Culicoides. In tropical and sub-tropical climates the virus is maintained in a continual cycle between the culicoid vector and the vertebrate host; however, bluetongue disease is also enzootic in …

Development of a single real-time RT-PCR method for the group-specific identification of African horsesickness virus and bluetongue virus
… but non-contagious disease caused by an orbivirus belonging to the Reoviridae family. The disease is classified as notifiable by the OlE because of the potential severe economic consequences that can result from outbreaks. Bluetongue, an arthropod-transmitted disease of wild and domestic …

A study of biting midge populations and an assessment of Bluetongue virus presence in southern Ontario, with a visual dichotomous key to the North American genera of Ceratopogonidae
… habits, some species act as vectors for viruses, many of which affect ruminant animals. This establishes ceratopogonids as possible threats to livestock farmers, and therefore it is important to understand their distribution and habits. This study focussed on collecting biting midge …

Antibiotic resistant and xenobiotic degrading bacteria that shape the microbiota of the vectors Aedes aegypti & Culicoides sonorensis
… geographic distribution continues to grow. The viruses spread by these vectors, such as Dengue and Bluetongue virus, are the causative agents of diseases with significant impact on public health and the livestock industry. Primary vector control methods involve the use of insecticides such as …

INVESTIGAÇÃO SOROEPIDEMIOLÓGICA DO VÍRUS DA LÍNGUA AZUL (BTV) EM REBANHOS CAPRINOS DO ESTADO DA PARAÍBA
… etiological agents that affects goats, the viruses deserve to be highlighted, by example the Bluetongue Virus (BTV). Due to the scarcity of data demonstrating this microorganism seroprevalence in goat herds in Paraiba territory, this study proposes to carry out an epidemiological analysis in …

Reagents and Tools to Identify Epizootic Hemorrhagic Disease Virus-2
… proteins from Epizootic Hemorrhagic Disease Virus (EHDV) to be used in quality control of vaccines produced by an industrial partner, and development of tools to identify EHDV. EHDV is an Orbivirus, which also includes Bluetongue Virus and African Horse Sickness, which are all transmitted …

The characterisation of aspects related to the single stranded RNA binding ability of African horsesickness virus nonstructural protein NS2
African horsesickness virus (AHSV) is a member of the Orbivirus genus and part of the family Reoviridae. It is a double stranded RNA virus with ten genome segments that encode seven structural and four nonstructural proteins. AHSV nonstructural protein NS2, encoded by segment eight, is a single …

Characterizing the effect of mutation recombination and reassortment on the genetic diversity of African horse sickness virus genomes
African horse sickness virus (AHSV) is a member of the Orbivirus genus within the Reoviridae family and the aetiological agent for African horse sickness (AHS). It is an arthropod-borne virus transmitted by biting midges belonging to various Culicoides spp. Nine antigenically distinct AHSV (AHSV …

Characterisation of promoter sequences in a Capripoxvirus genome
Capripoxviruses are of particular interest as live recombinant vectors for use in the veterinary field, since their host-range is restricted to cattle, goats and sheep. The work presented in this thesis is a preliminary study undertaken on the South African Neethling vaccine strain of lumpy skin …
