potential transmission of west nile virus in the british isles: an ecological review of candidate mosquito bridge vectors.west nile virus (wnv) transmitted by mosquitoes (diptera: culicidae) infects various vertebrates, being pathogenic for birds, horses and humans. after its discovery in tropical africa, sporadic outbreaks of wnv occurred during recent decades in eurasia, but not the british isles. wnv reached new york in 1999 and spread to california by 2003, causing widespread outbreaks of west nile encephalitis across north america, transmitted by many species of mosquitoes, mainly culex spp. the periodic reapp ...200515752172
natural vectors of dirofilariasis in rural and urban areas of the tuscan region, central italy.entomological investigations by means of dog- and human-baited traps were carried out in summers 2000-2002 in urban and rural areas of the tuscan region in central italy. the aim of the study was to define the mosquito species involved in the transmission of dirofilaria nematodes and to assess the risk that their presence might represent for animal and human health. nocturnal fieldwork on host-seeking activity and feeding preferences was followed by microscopic identification of the mosquito spe ...200616739418
distribution of mosquito species in areas with high and low incidence of classic kaposi's sarcoma and seroprevalence for hhv-8.the 'promoter-arthropod' hypothesis, which postulates that exposure to the bites of certain species of haematophagous arthropods is an environmental risk cofactor linked to human herpes virus 8 (hhv-8) and kaposi's sarcoma, was investigated in the po river valley, northern italy. the presence and density of adult female mosquitoes (diptera: culicidae) was determined by cdc light trap catches in two adjacent districts, at variance with respect to kaposi's sarcoma incidence and hhv-8 seroprevalenc ...200616871701

mosquitoes (diptera: culicidae) and their relevance as disease vectors in the city of vienna, austria.mosquitoes (diptera: culicidae) are important vectors for a wide range of pathogenic organisms. as large parts of the human population in developed countries live in cities, the occurrence of vector-borne diseases in urban areas is of particular interest for epidemiologists and public health authorities. in this study, we investigated the mosquito occurrence in the city of vienna, austria, in order to estimate the risk of transmission of mosquito-borne diseases. mosquitoes were captured using di ...201425468380
monitoring of west nile virus in mosquitoes between 2011-2012 in hungary.west nile virus (wnv) is a widely distributed mosquito-borne flavivirus. wnv strains are classified into several genetic lineages on the basis of phylogenetic differences. whereas lineage 1 viruses are distributed worldwide, lineage 2 wnv was first detected outside of africa in hungary in 2004. since then, wnv-associated disease and mortality in animal and human hosts have been documented periodically in hungary. after the first detection of wnv from a pool of culex pipiens mosquitoes in 2010, s ...025229703
host-seeking behavior and arbovirus detection in mosquitoes of habahe county, xinjiang uigur autonomous region, china.mosquitoes in habahe county of xinjiang uigur autonomous region in china are considered a serious nuisance problem to local residents, but little is known of their role in enzootic disease. therefore, host-seeking behavior and virus detection in mosquitoes were investigated in this study. adult host-seeking mosquitoes were sampled using the centers for disease control and prevention (cdc) light traps operated at three locations in june through august 2008. nine traps were used at each location a ...201526675454
first molecular identification of dirofilaria spp. (onchocercidae) in mosquitoes from serbia.dirofilariosis is a common and widespread veterinary health issue in several european countries with notable zoonotic potential. the causative agents are dirofilaria immitis and dirofilaria repens nematoda species which are transmitted by different mosquito vectors. similar to other mosquito-borne infections, the knowledge about mosquito species involved in disease transmission is crucial for the complex understanding of local transmission cycles. since there is no available data on mosquito spe ...201627193348
circulation of dirofilaria repens, setaria tundra, and onchocercidae species in hungary during the period 2011-2013.dirofilaria repens and recently dirofilaria immitis are known to be endemic in hungary. since there is no related research on dirofilaria carrier mosquito species from hungary, we conducted a three-year mosquito surveillance study between 2011 and 2013. during the study period we examined 23,139 female mosquitoes with a generic filaria-specific taqman pcr assay, and characterized them by sequencing a 500 bp segment of 12s rrna. an important result of our study was the detection of setaria tundra ...201526412142

diversity and ecology survey of mosquitoes potential vectors in belgian equestrian farms: a threat prevention of mosquito-borne equine arboviruses.emergence of west nile virus was recently recorded in several european countries, which can lead to severe health problems in horse populations. europe is also at risk of introduction of mosquito-borne equine alphavirus from americas. prevention of these arboviruses requires a clear understanding of transmission cycles, especially their vectors. to characterize mosquito fauna, their ecology and identify potential vectors of equine arboviruses in belgium, entomological surveys of six equestrian f ...201626775817
ecological niche modelling of potential west nile virus vector mosquito species and their geographical association with equine epizootics in italy, west nile virus (wnv) equine outbreaks have occurred annually since 2008. characterizing wnv vector habitat requirements allows for the identification of areas at risk of viral amplification and transmission. maxent-based ecological niche models were developed using literature records of 13 potential wnv italian vector mosquito species to predict their habitat suitability range and to investigate possible geographical associations with wnv equine outbreak occurrence in italy from 2008 ...201424121802
molecular detection of six (endo-) symbiotic bacteria in belgian mosquitoes: first step towards the selection of appropriate paratransgenesis candidates.actually, the use of symbiotic bacteria is one of alternative solution to avoid vector resistance to pesticides. in belgium, among 31 identified mosquito species, 10 were considered as potential vectors. given to introduction risks of arbovirosis, the purpose of this study was to investigate the presence of symbiosis bacteria in potential mosquito vectors. eleven species caught from 12 sites in belgium were used: culex pipiens s.l., culex torrentium, culex hortensis, anopheles claviger, anophele ...201626670313

mosquitoes of north-western europe as potential vectors of arboviruses: a review.the intensification of trade and travel is linked to the growing number of imported cases of dengue, chikungunya or zika viruses into continental europe and to the expansion of invasive mosquito species such as aedes albopictus and aedes japonicus. local outbreaks have already occurred in several european countries. very little information exists on the vector competence of native mosquitoes for arboviruses. as such, the vectorial status of the nine mosquito species largely established in north- ...201931739553
wolbachia symbionts in mosquitoes: intra- and intersupergroup recombinations, horizontal transmission and evolution.many mosquitoes harbour wolbachia symbionts that could affect the biology of their host in different ways. evolutionary relationships of mosquitoes' wolbachia infection, geographical distribution and symbiont prevalence in many mosquito species are not yet clear. here, we present the results of wolbachia screening of 17 mosquito species of four genera-aedes, anopheles, coquillettidia and culex collected from five regions of eastern europe and the caucasus in 2012-2016. based on multilocus sequen ...201930708172
