Japanese encephalitis virus (JEV) is the principal cause of mosquito-borne in human populations within Asia. If introduced into new geographic areas, it could have further implications for public and animal health. However, potential mosquito vectors transmission not been fully investigated. The Asian tiger mosquito, Aedes albopictus, has emerged Europe now expanding its geographical range more northerly latitudes. Culex quinquefasciatus, although absent from Europe, detected Turkey, a...
Usutu virus (USUV) is an emerging zoonotic arbovirus in Europe, where it primarily impacts Eurasian blackbirds (Turdus merula). For mosquito-borne viruses to persist temperate areas, transovarial transmission vectors or overwintering either hosts diapausing must occur facilitate autochthonous transmission. We undertook surveillance of and 2021 elucidate whether USUV had overwintered the United Kingdom (UK) following its initial detection there 2020. From 175 dead bird submissions, we...
West Nile virus (WNV) is a positive-sense single-stranded RNA belonging to the Flaviviridae family and maintained in an enzootic cycle between avian hosts mosquito vectors. Humans, horses other mammals are susceptible infection but dead-end due low viraemia. The disease can manifest itself variety of clinical signs symptoms people from mild fever severe encephalitis morbidity. There no vaccines licensed for human protection, parts Europe, North America, Africa Australia have commercially...
Babesiosis, a disease in humans and animals is caused by piroplasms from the genus Babesia transmitted ixodid ticks. Bovine babesiosis, commonly called redwater fever, reported cattle many regions of British Isles. The presence questing ticks United Kingdom (UK) its potential impact on public animal health has not been widely studied. Therefore, this study aimed to assess spp. England Wales using collected over six-year period. Questing Ixodes ricinus nymphs were at 20 recreational areas...
Sindbis virus (SINV) is the causative agent of a febrile infection commonly called Ockelbo disease, Pogosta disease or Karelian fever in northern Europe. Finland, Sweden, Russia and South Africa experience periodic SINV outbreaks. classified within family Togaviridae genus Alphavirus. Symptoms humans include joint inflammation pain, fever, rash fatigue. In some cases, symptoms can persist for years after recovery from initial infection. Clinical signs are rarely reported animals, although...
Japanese encephalitis (JE) is an infection that occurs predominantly in Asia and the Pacific Islands. It transmitted by mosquito bites, with main vector being Culex tritaeniorhynchus, maintained enzootic cycles involving pigs, wild birds mosquitoes. JE caused virus (JEV), a zoonotic pathogen also causes disease mammals such as pigs horses. In humans, most symptoms are mild or flu-like but can progress to encephalitis. Pigs considered amplification hosts, sows may have gestational...
A number of zoonotic mosquito-borne viruses have emerged in Europe recent decades. Batai virus (BATV), a member the genus Orthobunyavirus, is one example relatively newly virus, having been detected mosquitoes and livestock. We conducted vector competency studies on three mosquito species at low temperature to assess whether Aedes Culex are susceptible infection with BATV.Colonised lines aegypti pipiens wild-caught species, detritus, were orally inoculated BATV strain 53.2, originally...
