Stretching the wings further- susceptibility of Culex pipiens Linnaeus to bovine ephemeral fever virus infection under experimental conditions.

Bovine ephemeral fever (BEF) is a significant viral disease of cattle in the tropical, subtropical, and temperate climatic zones. This disease is also known as three-day sickness due to the spontaneous recovery of the cattle within a short period (usually 3-5 days). Despite its short duration, the disease may have a considerable impact.

Insights on Transmission, Spread, and Possible Endemization of Selected Arboviruses in Israel-Interim Results from Five-Year Surveillance.

Outbreaks of arthropod-borne (arbo) viruses that infect livestock impact the health and welfare of domestic and wild animals are often responsible for significant economic losses in livestock production. Surveillance and early warning systems effectively predict the emergence and re-emergence of arboviral disease. This paper presents the interim results of five years monitoring the exposure of sentinel naïve heifers and biting midges (Diptera; Ceratopogonidae) to bovine ephemeral fever virus (BEFV), Simbu serogroup viruses, bluetongue viruses (BTV), and epizootic hemorrhagic disease viruses (EHDV).

Genomic Detection of Schmallenberg Virus, Israel.

We discuss genomic detection of Schmallenberg virus in both Culicoides midges and affected ruminants during June 2018-December 2019, demonstrating its circulation in Israel. This region is a geographic bridge between 3 continents and may serve as an epidemiologic bridge for potential Schmallenberg virus spread into Asia.

Seasonal and spatial variation in Culicoides community structure and their potential role in transmitting Simbu serogroup viruses in Israel.

Culicoides biting midges (Diptera: Ceratopogonidae) are a successful group of small (1-3 mm) haematophagous flies, some species of which are biological vectors of veterinary arboviruses, such as bluetongue virus, epizootic haemorrhagic disease virus, African horse sickness virus and Simbu serogroup viruses. In this study, we examine seasonal and spatial effects on the presence and distribution of Culicoides communities associated with ruminant and equine farms in Israel, and their infection with Simbu serogroup viruses. Our results demonstrate that both the vectors and the viruses are widely spread in Israel, including regions that were previously considered Culicoides-free.
