arbovirus infections in sarawak: the role of the domestic pig.the possible role of pigs as arbovirus maintenance hosts and their importance as amplifier hosts was studied. blood samples from 464 pigs of all ages collected in 1962 and 1964 were tested against 10 arboviruses. antibodies to japanese encephalitis and getah viruses were particularly prevalent and their calculated monthly infection rates were 19-5% and 13-3% respectively. in 1969, 447 pigs were bled monthly throughout the year and the infection rates for japanese encephalitis virus were calculat ...19761265821
getah virus in aedes vexans nipponii and culex tritaeniorhynchus: vector susceptibility and ability to transmit.vector competences of aedes (ae.) vexans nipponii (nip.) and culex (cx.) tritaeniorhynchus to getah virus were assessed by using a membrane feeding technique. the getah virus was present at high titer in both species of mosquitoes after 21 days of extrinsic incubation at 28 degrees c. infection rates on 21 post-feeding were 100 per cent (4/4) for ae. vexans nip. at a virus dosage of 10(5.3) pfu/ml and 60 per cent (3/5) for cx. tritaeniorhynchus at similar virus dosage. more than 10(3.5) pfu of v ...19836312927
distribution of arboviruses and mosquitoes in northwestern yunnan province, china.from july to september in 2005 and 2006, a survey was conducted to identify mosquito species and mosquito-borne arboviruses at elevations ranging from 900-3280 m between 24 degrees 00' n and 29 degrees 00' n latitude in the northwestern part of yunnan province, china. a total of 54,879 mosquitoes representing 15 species and 4 genera was collected using uv light traps at 59 sites. culex tritaeniorhynchus and anopheles sinensis were the most abundant species. the density of mosquitoes as well as t ...200919196130
mosquitoes of western yunnan province, china: seasonal abundance, diversity, and arbovirus associations.the western borderland between yunnan province, china, and myanmar is characterized by a climate that facilitates year-round production of mosquitoes. numerous mosquito-transmitted viruses, including japanese encephalitis virus circulate in this area. this project was to describe seasonal patterns in mosquito species abundance and arbovirus activity in the mosquito populations.201324146951
[isolation and identification of mosquito-borne arboviruses in yuncheng city, shanxi province, 2012].to investigate the species and distribution of mosquitoes and mosquito-borne arboviruses in yuncheng city of shanxi province, china.201525975552
[investigation on mosquitoes and mosquito-borne viruses in dehong prefecture, yunnan province, 2007 and 2010].to investigate the distribution patterns of mosquito and mosquito-borne viruses in dehong prefecture, yunnan province, china.201425059361
distribution of mosquitoes and mosquito-borne viruses along the china-myanmar border in yunnan province.a total of 54,673 mosquitoes were collected at 11 sites located near the china-myanmar border in the western part of yunnan province during july and august 2007. there were 29 species in 4 genera identified from the collections, including 12 species of culex, 12 species of anopheles, 3 species of aedes, and 2 species of armigeres. culex tritaeniorhynchus giles (67.9%, 37,119/54,673) and anopheles sinensis wiedemann (25.9%, 14,170/54,673) were the most abundant species in this investigation. viru ...201222627302
pigsties near dwellings as a potential risk factor for the prevalence of japanese encephalitis virus in adult in shanxi, china.the increasing trend of adult cases of japanese encephalitis (je) in china, particularly in northern china, has become an important public health issue. we conducted an epidemiological investigation in the south of shanxi province to examine the relationships between mosquitoes, japanese encephalitis virus (jev), and adult je cases.201728592296
complete genome sequencing and phylogenetic analysis of a getah virus strain (genus alphavirus, family togaviridae) isolated from culex tritaeniorhynchus mosquitoes in nagasaki, japan in 2012.getah virus (getv; genus alphavirus, family togaviridae) is a mosquito-borne virus known to cause disease in horses and pigs. in 2014, for the first time in ∼30 years, a sudden getv outbreak occurred among racehorses in ibaraki, japan. two years before this outbreak, we obtained multiple getv isolates from culex tritaeniorhynchus mosquitoes collected in nagasaki, japan and determined the whole genome sequence of getv isolate 12ih26. our phylogenetic analysis of getv strains revealed that the iso ...201627827562
laboratory transmission of japanese encephalitis, west nile, and getah viruses by mosquitoes (diptera: culicidae) collected near camp greaves, gyeonggi province, republic of korea 2003.we conducted experimental studies to evaluate mosquitoes captured in paju county, gyeonggi province, republic of korea, for their ability to transmit west nile virus (family flaviviridae, genus flavivirus, wnv), japanese encephalitis virus (family flaviviridae, genus flavivirus, jev), and getah virus (family togaviridae, genus alphavirus, getv) under laboratory conditions. both culex pipiens pallens coquillett and culex tritaeniorhynchus giles were highly susceptible to infection with wnv, with ...200617017248
viruses isolated from mosquitoes collected in sri lanka.attempts to isolate viruses from 178,181 unengorged female mosquitoes collected from different ecologic areas of sri lanka yielded 31 isolates: 17 of japanese encephalitis (je) virus, nine of getah virus, three of a batai-related bunyavirus, and two of arkonam virus. culex tritaeniorhynchus and mansonia uniformis mosquitoes were found to carry je virus in a dry zone nonepidemic area, and cx. pseudovishnui was found to carry it in a wet zone nonepidemic area. japanese encephalitis virus was isola ...19947915499
