Secreted Nonstructural Protein 3 is a Pathogenic Determinant of Orbivirus

Advanced Science
Orbivirus is a genus of double‐stranded RNA viruses that infect a broad spectrum of arthropods and vertebrates. Hemorrhage across different organs is a hallmark pathological feature of orbivirus infection, as exemplified by the bluetongue virus (BTV ...

Seroprevalence of Arboviruses and Genetic Characterization of Orbiviruses in Sloths from Western Panama [PDF]

Viruses
Arthropod-borne viruses (arboviruses) are an increasingly significant threat to public health in tropical regions. In this study, we investigated the seroprevalence of various arboviruses in two species of sloth (Choloepus hoffmanni and Bradypus ...

Injection but not ingestion of a mixed virus suspension in Queensland fruit fly (Bactrocera tryoni) shifts persistent covert infection to acute pathology. [PDF]

Pest Manag Sci
Covert and persistent infections with multiple insect‐specific viruses are common in pest fruit flies and may affect pest management strategies. Our study investigated the host effects and viral loads of cripavirus and iflavirus as persistent infections in Queensland fruit fly, and after injection and ingestion of a mixed virus suspension containing ...

Clinical signs, clinical pathology and outcomes in horses infected naturally with equine encephalosis virus. [PDF]

Equine Vet J
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 ...

Bluetongue Virus Serotype 3 Follow-Up of the 2024 Outbreak in Two Belgian Zoos. [PDF]

Transbound Emerg Dis
In summer 2024, Western Europe experienced extensive outbreaks of bluetongue virus Serotype 3 (BTV‐3), a Culicoides‐borne orbivirus. Clinical disease was first detected in August 2024 in one of two Belgian zoos, predominantly affecting European bison (Bison bonasus) and American bison (Bison bison).
