An extensive entomological survey was performed in 2009 to establish the presence and distribution of mosquito arboviruses in this region, with particular reference to flaviviruses.\\n\\nMETHODOLOGY/PRINCIPAL FINDINGS: From May 6 to October 31, a total of 190,516 mosquitoes were sampled in georeferenced stations, grouped in 1,789 pools according date of collection, location, and species, and analyzed by reverse transcription polymerase chain reaction (RT-PCR) to detect the presence of RNA belong to Flavivirus genus. WNV was detected in 27 mosquito pools, producing sequences similar to those of birds and human strains obtained in 2008 outbreak, pointed out the probable virus overwintering. Isolation of WNV was achieved from one of these pools. Moreover 56 pools of mosquitoes tested positive for Usutu virus (USUV). Most PCR positive pools consisted of Culex pipiens, which also was the most analyzed mosquito species (81.4% of specimens); interestingly, USUV RNA was also found in two Aedes albopictus mosquito pools. Simultaneous circulation of WNV and USUV in the survey area was highlighted by occurrence of 8 mosquito WNV- and USUV-positive pools and by the overlaying of the viruses \"hot spots\", obtained by kernel density estimation (KDE) analysis. Land use of sampled stations pointed out a higher proportion of WNV-positive Cx. pipiens pool in rural environments respect the provenience of total sampled pool, while the USUV-positive pools were uniformly captured in the different environments.\\n\\nCONCLUSIONS/SIGNIFICANCE: Obtained data highlighting the possible role of Cx. pipiens mosquito as the main vector for WNV and USUV in Northern Italy, and the possible involvement of Ae. albopictus mosquito in USUV cycle. The described mosquito-based surveillance could constitute the foundation for a public health alert system targeting mosquito borne arboviruses.", "link"=>"http://www.mendeley.com/research/evidence-simultaneous-circulation-west-nile-usutu-viruses-mosquitoes-sampled-emiliaromagna-region-it", "reader_count"=>62, "reader_count_by_academic_status"=>{"Unspecified"=>3, "Professor > Associate Professor"=>4, "Student > Doctoral Student"=>5, "Researcher"=>20, "Student > Ph.

Simultaneous circulation of WNV and USUV in the survey area was highlighted by occurrence of 8 mosquito WNV- and USUV-positive pools and by the overlaying of the viruses “hot spots”, obtained by kernel density estimation (KDE) analysis. Land use of sampled stations pointed out a higher proportion of WNV-positive <em>Cx. pipiens</em> pool in rural environments respect the provenience of total sampled pool, while the USUV-positive pools were uniformly captured in the different environments.</p><h3>Conclusions/Significance</h3><p>Obtained data highlighting the possible role of <em>Cx. pipiens</em> mosquito as the main vector for WNV and USUV in Northern Italy, and the possible involvement of <em>Ae. albopictus</em> mosquito in USUV cycle. The described mosquito-based surveillance could constitute the foundation for a public health alert system targeting mosquito borne arboviruses.</p></div>", "links"=>[], "tags"=>["simultaneous", "circulation", "nile", "usutu", "viruses", "mosquitoes", "sampled", "emilia-romagna", "2009"], "article_id"=>140078, "categories"=>["Cancer", "Biological Sciences", "Ecology", "Neuroscience"], "users"=>["Mattia Calzolari", "Paolo Bonilauri", "Romeo Bellini", "Alessandro Albieri", "Francesco Defilippo", "Giulia Maioli", "Giorgio Galletti", "Antoni Gelati", "Ilaria Barbieri", "Marco Tamba", "Davide Lelli", "Elena Carra", "Paolo Cordioli", "Paola Angelini", "Michele Dottori"], "doi"=>["https://dx.doi.org/10.1371/journal.pone.0014324.s001", "https://dx.doi.org/10.1371/journal.pone.0014324.s002"], "stats"=>{"downloads"=>6, "page_views"=>11, "likes"=>0}, "figshare_url"=>"https://figshare.com/articles/Evidence_of_Simultaneous_Circulation_of_West_Nile_and_Usutu_Viruses_in_Mosquitoes_Sampled_in_Emilia_Romagna_Region_Italy_in_2009/140078", "title"=>"Evidence of Simultaneous Circulation of West Nile and Usutu Viruses in Mosquitoes Sampled in Emilia-Romagna Region (Italy) in 2009", "pos_in_sequence"=>0, "defined_type"=>4, "published_date"=>"2010-12-15 00:01:18"}
