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 ...

Culicoides biting midges (Diptera: Ceratopogonidae) feeding on donkeys in the United Kingdom, with reference to the risk of transmission and persistence of African horse sickness virus. [PDF]

Med Vet Entomol
Culicoides biting midges were collected at a donkey sanctuary in the United Kingdom using UV light‐suction traps. Culicoides were found in abundance and all specimens were identified to species level. Blood‐feeding on donkeys was confirmed by polymerase chain reaction (PCR) and sequencing of host bloodmeals. Donkeys could play a significant role in the

Serological Cross-Reactions between Expressed VP2 Proteins from Different Bluetongue Virus Serotypes

Viruses, 2021
Bluetongue (BT) is a severe and economically important disease of ruminants that is widely distributed around the world, caused by the bluetongue virus (BTV).

Comprehensive Viral Detection and Profiling of Plasma Cell-Free RNA in Patients With Suspected Hemophagocytic Lymphohistiocytosis. [PDF]

J Med Virol
ABSTRACT Hemophagocytic lymphohistiocytosis (HLH) is a severe, rapidly progressive disease. While viral infection is considered a common etiology of pediatric HLH, specific causative viruses other than the Epstein‐Barr virus (EBV) have been rarely identified.

Using Zoos as Sentinels for Re-Emerging Arboviruses: Vector Surveillance during an Outbreak of Epizootic Hemorrhagic Disease at the Minnesota Zoo

Pathogens, 2023
Vector-borne disease prevalence is increasing at a time when surveillance capacity in the United States is decreasing. One way to address this surveillance deficiency is to utilize established infrastructure, such as zoological parks, to investigate ...

Orbivirus Screening from Imported Captive Oryx in the United Arab Emirates Stresses the Importance of Pre-Import and Transit Measures

Pathogens, 2022
From 1975 to 2021, the United Arab Emirates (UAE) imported more than 1300 live Arabian oryxes (AOs) and scimitar-horned oryxes (SHOs) for conservation programs.

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 ...

Orbivirus NS4 Proteins Play Multiple Roles to Dampen Cellular Responses

Viruses, 2023
Non-structural protein 4 (NS4) of insect-borne and tick-borne orbiviruses is encoded by genome segment 9, from a secondary open reading frame. Though a protein dispensable for bluetongue virus (BTV) replication, it has been shown to counter the ...

Inhibition of the IFN Response by Bluetongue Virus: The Story So Far

Frontiers in Microbiology, 2021
Bluetongue virus (BTV) is the prototypical orbivirus that belongs to the Reoviridae family. BTV infection produces a disease in ruminants, particularly in sheep, that results in economic losses through reduced productivity. BTV is transmitted by the bite
