Concurrent infection of bluetongue and peste-des-petits-ruminants virus in small ruminants in Haryana State of India [PDF]

, 2018
Bluetongue (BT) and peste-des-petits-ruminants (PPR) are major transboundary diseases of small ruminant, which are endemic in India. Testing of bluetongue virus (BTV) and peste-des-petits-ruminants virus (PPRV) from recent outbreaks (2015–2016) in ...

Clinical signs, clinical pathology and outcomes in horses infected naturally with equine encephalosis virus

Equine Veterinary Journal, EarlyView.
Abstract Background Equine encephalosis (EE) is caused by an Orbivirus from the family Sedoreoviridae and is thus similar to African horse sickness (AHS) and Bluetongue viruses (BTV). These viruses are transmitted by Culicoides midges. Equine encephalosis can infect horses, donkeys and zebras sub‐clinically while only horses develop clinical disease ...

Orbivirus Structure and Assembly

Virology, 1996
Orbiviruses (Reoviridae family) are complex nonenveloped RNA viruses with seven structural proteins and a RNA genome consisting of 10 variously sized double-stranded RNA segments. Significant advances in orbivirus research have been made in recent years through the use of gene manipulation techniques coupled with the baculovirus expression system ...

The Interplay between Bluetongue Virus Infections and Adaptive Immunity

Viruses, 2021
Viral infections have long provided a platform to understand the workings of immunity. For instance, great strides towards defining basic immunology concepts, such as MHC restriction of antigen presentation or T-cell memory development and maintenance ...

Bluetongue: a historical and epidemiological perspective with the emphasis on South Africa [PDF]

, 2012
Bluetongue (BT) is a non-contagious, infectious, arthropod transmitted viral disease of domestic and wild ruminants that is caused by the bluetongue virus (BTV), the prototype member of the Orbivirus genus in the family Reoviridae.

Culicoides species involved in the BTV‐3 epidemic, the Netherlands, 2023–2024

Medical and Veterinary Entomology, EarlyView.
A high amount of Culicoides‐midges were captured using Onderstepoort light traps on farms with animals infected with bluetongue serotype 3 (BTV‐3) at the beginning of the outbreak in 2023. Species, sex and parity of the captured Culicoides‐midges were morphologically determined and gravid and parous Culicoides‐midges have been selected and pooled for ...

Isolation and Phylogenetic Grouping of Equine Encephalosis Virus in Israel

Emerging Infectious Diseases, 2011
During 2008–2009 in Israel, equine encephalosis virus (EEV) caused febrile outbreaks in horses. Phylogenetic analysis of segment 10 of the virus strains showed that they form a new cluster; analysis of segment 2 showed ≈92% sequence identity to EEV-3 ...

Safety and Efficacy of Plant‐Produced Trivalent Virus‐Like Particle Vaccine Candidate Against Bluetongue Disease

Plant Biotechnology Journal, EarlyView.
ABSTRACT Bluetongue (BT) is a non‐contagious, insect‐transmitted disease of wild and domestic ruminants caused by bluetongue virus (BTV). Effective control of BT disease relies on vaccination against prevalent or seasonal serotypes using live attenuated or inactivated vaccines.
