| revisited its2 phylogeny of anopheles (anopheles) hyrcanus group mosquitoes: reexamination of unidentified and misidentified its2 sequences. | the anopheles (anopheles) hyrcanus group of mosquitoes is very important for human health because some are malarial vector mosquitoes. despite their pathological importance, some unidentified internal transcribed spacer 2 (its2) sequences have been reported from members of this group, and their phylogenetic relationships have been rarely understood. in the present study, 84 its2 sequences for the hyrcanus group members were retrieved from genbank. the detailed sequence comparison unambiguously r ... | 2007 | 17514381 |
| anopheles kleini, anopheles pullus, and anopheles sinensis: potential vectors of plasmodium vivax in the republic of korea. | anopheles sinensis wiedemann (63.3%) was the most abundant anopheles mosquito captured at cowshed resting collections in malaria high-risk areas (northern gyeonggi province) near the demilitarized zone (dmz) in korea during 2005, followed by anopheles kleini rueda (24.7%) and anopheles pullus m. yamada (8.7%). at cowshed resting collections in malaria low-risk areas (jeonnam and gyeongnam provinces), an. sinensis accounted for 96.8% of all anopheles spp. collected, followed by an. kleini rueda ( ... | 2007 | 18047210 |

| distribution of malaria vectors and incidence of vivax malaria at korean army installations near the demilitarized zone, republic of korea. | as a result of the reintroduction of malaria in the republic of korea (rok) in 1993 and the threat to military and civilian populations, the korea military national defense (mnd) increased emphasis on vector control in 2012 at rok army (roka) installations located near the dmz, while decreasing chemoprophylaxis, fearing potential drug resistance. mosquito surveillance demonstrated a need for continuous monitoring of disease patterns among roka soldiers and vector malaria infection rates to ensur ... | 2016 | 27150110 |
| genetic compatibility between anopheles lesteri from korea and anopheles paraliae from thailand. | to assess differentiation and relationships between anopheles lesteri and anopheles paraliae we established three and five iso-female lines of an. lesteri from korea and an. paraliae from thailand, respectively. these isolines were used to investigate the genetic relationships between the two taxa by crossing experiments and by comparing dna sequences of ribosomal dna second internal transcribed spacer (its2) and mitochondrial dna cytochrome c oxidase subunit i (coi) and subunit ii (coii). resul ... | 0 | 23778670 |
| Preliminary vivax malaria vector competence for three members of the Anopheles hyrcanus group in the Republic of Korea. | In a study on the comparative susceptibility of Anopheles kleini, An. lesteri, and An. sinensis to Plasmodium vivax, we examined the feeding of laboratory-reared mosquitoes on blood of a patient carrying gametocytes from the Republic of Korea. Sporozoites in salivary glands from day 14 postfeeding were detected in An. kleini and An. lesteri with numbers high enough to initiate infection, while no sporozoites were detected in the salivary glands of An. sinensis. This result suggests that An. klei ... | 2011 | 22017097 |
