Anopheles cracens has been incriminated as the vector of human knowlesi malaria in peninsular Malaysia. Besides, it is a good laboratory vector of Plasmodium falciparum and P. vivax. The distribution of An. cracens overlaps with that of An. maculatus, the human malaria vector in peninsular Malaysia that seems to be refractory to P. knowlesi infection in natural settings. Whole genome sequencing was performed on An. cracens and An. maculatus collected here. The draft genome of An. cracens was 395 Mb in size whereas the size of An. maculatus draft genome was 499 Mb. Comparison with the published Malaysian An. maculatus genome suggested the An. maculatus specimen used in this study as a different geographical race. Comparative analyses highlighted the similarities and differences between An. cracens and An. maculatus, providing new insights into their biological behavior and characteristics.
克氏按蚊已被确认为马来西亚半岛人类诺氏疟原虫疟疾的传播媒介。此外,它还是恶性疟原虫和间日疟原虫的优良实验室传播媒介。克氏按蚊的分布与马来西亚半岛人类疟疾传播媒介——多斑按蚊的分布重叠,而多斑按蚊在自然环境中似乎对诺氏疟原虫感染具有抗性。对这里采集的克氏按蚊和多斑按蚊进行了全基因组测序。克氏按蚊的基因组草图大小为395兆碱基对,而多斑按蚊基因组草图大小为499兆碱基对。与已发表的马来西亚多斑按蚊基因组进行比较表明,本研究中使用的多斑按蚊标本属于不同的地理种群。比较分析突出了克氏按蚊和多斑按蚊之间的异同,为它们的生物学行为和特征提供了新的见解。
