| detection and monitoring of mosquito flaviviruses in spain between 2001 and 2005. | between the years 2001 and 2005, a total of 72,895 female mosquitoes were trapped during their season of abundance, and analyzed. they were sorted into 4,723 pools belonging to 20 culicidae species from the anopheles, aedes, ochlerotatus, culex, culiseta, coquillettidia, and uranotaenia genera. the aim was to detect arboviral rna directly from mosquito homogenates for the genera alphavirus, flavivirus, and phlebovirus. the study formed part of general arbovirus transmission research in four of t ... | 2009 | 18959502 |
| isolation and characterization of a new mosquito flavivirus, quang binh virus, from vietnam. | in recent years, a number of flaviviruses that replicate only in an arthropod host have been discovered and characterized. we describe here the isolation and characterization of a new mosquito-only flavivirus in this group. the virus was isolated from culex tritaeniorhyncus mosquitoes collected in vietnam in 2002 and was found to be genetically different from mosquito flaviviruses described previously. we propose the isolate be named quang binh virus. | 2009 | 19347244 |
| evidence for ribosomal frameshifting and a novel overlapping gene in the genomes of insect-specific flaviviruses. | flaviviruses have a positive-sense, single-stranded rna genome of approximately 11 kb, encoding a large polyprotein that is cleaved to produce approximately 10 mature proteins. cell fusing agent virus, kamiti river virus, culex flavivirus and several recently discovered flaviviruses have no known vertebrate host and apparently infect only insects. we present compelling bioinformatic evidence for a 253-295 codon overlapping gene (designated fifo) conserved throughout these insect-specific flavivi ... | 2010 | 20097399 |
| distribution and phylogenetic comparisons of a novel mosquito flavivirus sequence present in culex tarsalis mosquitoes from western canada with viruses isolated in california and colorado. | in a previous study, a new flavivirus genome sequence was identified in culex tarsalis mosquitoes obtained in alberta, canada and was shown to be genetically related to but distinct from members of the insect-specific flaviviruses. nonstructural protein 5-encoding sequences amplified from cx. tarsalis pools from western canada have shown a high similarity to genome sequences of novel flaviviruses isolated from mosquitoes in california and colorado. despite wide distribution of this virus, design ... | 2011 | 21734143 |
| flavidb: a data mining system for knowledge discovery in flaviviruses with direct applications in immunology and vaccinology. | the flavivirus genus is unusually large, comprising more than 70 species, of which more than half are known human pathogens. it includes a set of clinically relevant infectious agents such as dengue, west nile, yellow fever, and japanese encephalitis viruses. although these pathogens have been studied extensively, safe and efficient vaccines lack for the majority of the flaviviruses. | 0 | 25544857 |
| [taxonomy of the sokuluk virus (sokv) (flaviviridae, flavivirus, entebbe bat virus group) isolated from bats (vespertilio pipistrellus schreber, 1774), ticks (argasidae koch, 1844), and birds in kyrgyzstan]. | complete genome sequencing of the sokuluk virus (sokv) isolated in kyrgyzstan from bats vespertilio pipistrellus and their obligatory parasites--argasidae koch, 1844, ticks was carried out. sokv was classified as attributed to the flaviviridae family, flavivirus genus. the maximum homology (71% for nucleotide and 79% for amino acid sequences) was detected with respect to the entebbe bat virus (entv). entv and sokv form a group joining to the yellow fever virus (yfv) within the limits of the mosq ... | 2016 | 25065143 |
| insect-specific flaviviruses in aedes mosquitoes in greece. | mosquitoes of the genus aedes are known vectors of pathogenic flaviviruses, and insect-specific flaviviruses (isfs) have been detected in members of this genus in numerous parts of the world. in order to gain insight into whether aedes mosquitoes in greece are infected by flaviviruses, 1173 aedes spp. mosquitoes collected in 2010 and 2012 were grouped in 53 pools and tested by rt nested pcr using flavivirus generic primers. eight pools (15.09 %) were found to be pcr positive: five pools (5/53, 9 ... | 2016 | 27198866 |
| mosquito surveillance in northwestern italy to monitor the occurrence of tropical vector-borne diseases. | mosquito-borne arboviruses (mbv) represent an important health problem, causing diseases and deaths both in human and animals mainly in tropical and subtropical countries. in recent years, they have emerged also in temperate regions where they have caused epidemics. of mounting concern among public health authorities in europe are zoonotic mosquito-borne viruses belonging to the flavivirus genus. the aim of this study was to carry out active surveillance on mosquitoes in two regions of northwest ... | 2013 | 24589116 |
| mosquito arbovirus survey in selected areas of kenya: detection of insect-specific virus. | many arboviral outbreaks have occurred in various locations in kenya. entomological surveys are suitable methods for revealing information about circulating arboviruses before human outbreaks are recognized. therefore, mosquitoes were collected in kenya to determine the distribution of arboviruses. | 2018 | 29991925 |
| field-captured aedes vexans (meigen, 1830) is a competent vector for rift valley fever phlebovirus in europe. | aedes vexans (meigen) is considered a nuisance species in central europe and the mediterranean region. it is an anthropophilic and mammalophilic floodwater mosquito involved in the transmission of several arboviruses. rift valley fever (rvf) is a relevant mosquito-borne zoonosis, affecting mainly humans and ruminants, that causes severe impact in public health and economic loses. due to globalization and climate change, the european continent is threatened by its introduction. the main purpose o ... | 2019 | 31619269 |
