Prediction of species composition ratios in pooled specimens of the Anopheles Hyrcanus group using quantitative sequencing
Abstract Background Plasmodium vivax is transmitted by members of the Anopheles Hyrcanus Group that includes six species in the Republic of Korea: Anopheles sinensis sensu stricto (s.s.), Anopheles pullus, Anopheles kleini, Anopheles belenrae, Anopheles lesteri, and Anopheles sineroides. Individual...
