摘要:

沃尔巴克氏体(Wolbachia)是一种在自然界节肢动物体内广泛存在、能经卵传递的革兰阴性胞内共生菌。估计约65%的昆虫种类和28%的蚊虫种类天然携带沃尔巴克氏体。当携带沃尔巴克氏体的雄蚊与不携带或者携带不同沃尔巴克氏体型的雌蚊交配,雌蚊产的卵将不会孵化,该性状称为胞质不相容性(cytoplasmic incompatibility,CI)。胞质不相容性赋予携带沃尔巴克氏体的雌蚊生殖优势,从而使其可以扩散到蚊群中去;同时沃尔巴克氏体在蚊媒体内能对多种人类病原体(如登革热病毒、黄病毒和疟原虫等)产生抗性。基于以上特性可建立2种虫媒病控制的新策略:①将野生的传病蚊媒改变成对人类病原体具有抗性的蚊虫,从而阻断蚊媒病的传播(种群替换);②持续诱导引起胞质不相容性的交配,从而压制或区域性根除传病蚊媒(种群压制)。

Abstract:

Wolbachia spp. are maternally transmitted Gram-negative endosymbiotic bacteria. With infection occurring in a wide range of invertebrates, Wolbachia is estimated to infect 65% of insect species and 28% of mosquito species in nature. An early embryo death, a phenotype referred to as cytoplasmic incompatibility (CI), will occur when infected males mate with uninfected females, or females that carry different type of Wolbachia. CI provides reproductive advantage to infected females, resulting in spread of Wolbachia into mosquito population. Furthermore, Wolbachia can confer mosquito resistant to a variety of human pathogens, including dengue virus, yellow fever virus and malaria parasites. This has led to large efforts to develop Wolbachia-based vector control strategies. One is referred to as population replacement, in which a disease susceptible wild type vector population is modified into a disease resistant population, resulting in blocking of disease transmission. Another is population suppression, in which CI mating is induced in the target population, resulting in suppression, or even eradication of a vector population.

Key words: Wolbachia, Cytoplasmic incompatibility, Population suppression, Population replacement
