ecological surveillance for west nile in catalonia (spain), learning from a five-year period of enhance early detection of west nile virus (wnv) transmission, an integrated ecological surveillance system was implemented in catalonia (north-eastern spain) from 2007 to 2011. this system incorporated passive and active equine surveillance, periodical testing of chicken sentinels in wetland areas, serosurveillance wild birds and testing of adult mosquitoes. samples from 298 equines, 100 sentinel chickens, 1086 wild birds and 39 599 mosquitoes were analysed. during these 5 years, no acute wn ...201423590452
low seroprevalence of west nile virus in blood donors from catalonia, spain.west nile virus (wnv) is an emerging arbovirus first recognized in europe in the 1950s. since then, outbreaks have been reported in several european countries. in 2010, the first wnv outbreak was recorded in spain, affecting the southern part of the country. we conducted a seroprevalence study in the catalonia region (northeastern spain), an area considered at high risk of arbovirus transmission. a total of 800 serum samples from blood donors were collected and screened for antibodies against wn ...201526581013

host-feeding patterns of native culex pipiens and invasive aedes albopictus mosquitoes (diptera: culicidae) in urban zones from barcelona, spain.the feeding patterns of haematophagous arthropods are of major importance in the amplification and transmission of infectious disease agents to vertebrate hosts, including humans. the establishment of new vector populations in nonnative range might alter transmission networks. the asian tiger mosquito aedes albopictus (skuse) represents an example of how an invasive species can alter the risk of viral transmission to humans. blood meal molecular identification from two sympatric mosquito species ...201121845962
