Introduction Bluetongue virus (BTV) is an arthropod-borne Orbivirus that almost solely transmitted by Culicoides biting midges and causes a globally important haemorrhagic disease, bluetongue (BT), in susceptible ruminants. Infection with BTV characterised immunosuppression substantial lymphopenia at peak viraemia the host. Methods In this study, role of cell-mediated immunity specific T-cell subsets pathogenesis, clinical outcome, viral dynamics, immune protection, onwards transmission to...
Background: In recent decades there has been a huge increase in the export of cut flowers from countries Africa and elsewhere to European flower markets, with vast majority first entering Netherlands for local use or export. Coincidentally, two significant livestock disease outbreaks caused by viruses associated other tropical regions, were detected (bluetongue virus, BTV, 2006) western Germany about 200 km border (Schmallenberg SBV, 2011). This study aimed determine whether Culicoides...
Schmallenberg virus (SBV) causes abortions, stillbirths and fetal malformations in naïve ruminants. The impact of the initial outbreak (2011/2012) on British sheep farms has been previously investigated, with higher farmer perceived impacts increased lamb ewe mortality reported SBV-affected farms. After several years low, or no, circulation UK flock once again became vulnerable to SBV infection. Re-emergence was confirmed autumn 2016. This study reports analysis a questionnaire designed...
In 2011–2012, northern European livestock faced a threat from newly emerged virus, Schmallenberg virus (SBV), only few years after major outbreak of bluetongue serotype 8 (BTV‐8). Like BTV‐8, SBV is transmitted by Culicoides biting midges to ruminants and spread throughout Europe. SBV, however, faster, reaching the UK within three months initial discovery. Adult show mild, if any, clinical signs; infection naive during vulnerable period gestation leads abortions, stillbirths fetal...
Bovine ephemeral fever virus (Rhabdoviridae: Ephemerovirus) (BEFV) causes bovine (BEF), an economically important disease of cattle and water buffalo. Outbreaks BEF in Africa, Australia, Asia the Middle East are characterized by high rates morbidity highly efficient transmission between hosts. Despite this, vectors BEFV remain poorly defined.Colony lines biting midges (Culicoides sonorensis) mosquitoes (Aedes aegypti, Culex pipiens quinquefasciatus) were infected with a strain originating...
Culicoides biting midges (Diptera: Ceratopogonidae) are biological vectors of internationally important arboviruses and inflict nuisance on humans, companion animals livestock. In temperate regions, transmission is limited by temperature thresholds, in both replication dissemination within the vector flight activity adult Culicoides. This study aims to determine cold-temperature thresholds for from UK under laboratory conditions. Over 18,000 adults were collected field using 4 W down-draught...
Culicoides biting midges (Diptera: Ceratopogonidae) are biological vectors of livestock arboviruses that cause diseases with significant economic, social and welfare impacts. Within temperate regions, movement during arbovirus outbreaks can be facilitated by declaring a 'seasonal vector-free period' (SVFP) winter when adult not active. In this study we carry out long-term monitoring emergence from larval development habitats at two farms in the UK to validate current definitions SVFP provide...
Here, we report the first complete genome of a bovine ephemeral fever virus (BEFV) isolate from an infected in Israel. The shares 95.3% identity with Turkish genomic sequence but contains α3 and γ open reading frames that are truncated compared to those existing BEFV sequences.
The objective of this study was to gather current, farmer‐reported data on the frequency occurrence, risk factors and treatment practices for sheep eye disease, ovine infectious keratoconjunctivitis (OIKC). A questionnaire regarding disease in completed by 135 farmers from four livestock markets. Most (87%) had observed OIKC their flock, 88% these within last 2 years. Farmers reported observing most cases winter months (51%) fewest summer (10%). They proposed housing forage feeding racks as...
