| emergence of genotype i of japanese encephalitis virus as the dominant genotype in asia. | japanese encephalitis virus (jev), a mosquito-borne zoonotic pathogen, is one of the major causes of viral encephalitis worldwide. previous phylogenetic studies based on the envelope protein indicated that there are four genotypes, and surveillance data suggest that genotype i is gradually replacing genotype iii as the dominant strain. here we report an evolutionary analysis based on 98 full-length genome sequences of jev, including 67 new samples isolated from humans, pigs, mosquitoes, midges. ... | 2011 | 21697481 |
| comparison of genotypes i and iii in japanese encephalitis virus reveals distinct differences in their genetic and host diversity. | japanese encephalitis (je) is an arthropod-borne disease associated with the majority of viral encephalitis cases in the asia-pacific region. the causative agent, japanese encephalitis virus (jev), has been phylogenetically divided into five genotypes. recent surveillance data indicate that genotype i (gi) is gradually replacing genotype iii (giii) as the dominant genotype. to investigate the mechanism behind the genotype shift and the potential consequences in terms of vaccine efficacy, human c ... | 2014 | 25056890 |
| surveillance of japanese encephalitis virus infection in mosquitoes in vietnam from 2006 to 2008. | japanese encephalitis virus (jev) infection in mosquitoes was monitored in vietnam from 2006 to 2008. a total of 15,225 mosquitoes, identified as 26 species in five genera were collected and 12,621 were grouped into 447 pools for examination of jev infection by assays for cytopathic effects in c6/36 cells and by rt-pcr to detect flavivirus rna. three jev strains were isolated from culex tritaeniorhynchus giles collected in northern and southern vietnam and two jev strains were isolated from cule ... | 2013 | 23358634 |
| a video clip of the biting midge culicoides anophelis ingesting blood from an engorged anopheles mosquito in hainan, china. | biting midges are hematophagus ectoparasites of insects, humans and other animals. culicoides (trithicoides) anophelis edwards1922 is a predator of engorged mosquitoes. | 2013 | 24499575 |
| detection of west nile virus in six mosquito species in synchrony with seroconversion among sentinel chickens in india. | west nile virus (wnv) is a zoonotic flavivirus maintained in mosquito-bird transmission cycle. although humans are accidental hosts, fatal outcomes following wnv infection have been reported from india. studies have identified wnv as an important etiological agent causing acute encephalitis syndrome in assam, northeast india. while circulation of wnv is evident, the role of vectors and avian hosts involved in the transmission remains unclear. in this study we identified local mosquito species fo ... | 2017 | 28061903 |
| geographic distribution of wolbachial infections in mosquitoes from thailand. | members of the genus wolbachia are inherited intracellular bacterial endosymbionts that infect a diverse range of arthropods. here i report the results of a survey of these endosymbionts in different mosquito species from six geographic regions of northern, northeastern, western, central, eastern and southern thailand. using gene amplification assays with wsp and groe gene primers, wolbachiae were detected in 999 mosquitoes representing 28 species of 1622 specimens collected representing 74 spec ... | 2013 | 23660513 |
| effectiveness of landmark- and semi-landmark-based geometric morphometric to identify four species of culex mosquitoes in thailand. | this research aims to study the effectiveness of landmark- and semi-landmark-based geometric morphometric (lmsl) in the identification of four culex vectors, namely, c. quinquefasciatus, c. visnui, c. sitiens, and c. whitmorei in thailand and also compared the potential between lmsl and the landmark-based geometric morphometric method (lm). | 2019 | 31583223 |
