Tsetse flies (Diptera: Glossinidae) are the sole vectors of African trypanosomes, the causative agent of sleeping sickness in human and nagana in animals. Like most eukaryotic organisms, Glossina species have established symbiotic associations with bacteria. Three main symbiotic bacteria have been found in tsetse flies: Wigglesworthia glossinidia, an obligate symbiotic bacterium, the secondary endosymbiont Sodalis glossinidius and the reproductive symbiont Wolbachia pipientis. In the present review, we discuss recent studies on the detection and characterization of Wolbachia infections in Glossina species, the horizontal transfer of Wolbachia genes to tsetse chromosomes, the ability of this symbiont to induce cytoplasmic incompatibility in Glossina morsitans morsitans and also how new environment-friendly tools for disease control could be developed by harnessing Wolbachia symbiosis.
采采蝇(双翅目:唾液科)是非洲锥虫的唯一传播媒介,非洲锥虫是导致人类昏睡病和动物那加那病的病原体。与大多数真核生物一样,舌蝇种与细菌建立了共生关系。在采采蝇中发现了三种主要的共生细菌:必须共生的细菌威氏泰勒虫、次要内共生体斯氏苏达利氏菌和生殖共生体沃尔巴克氏体。在本综述中,我们讨论了最近关于在舌蝇种中检测和描述沃尔巴克氏体感染、沃尔巴克氏体基因向采采蝇染色体的水平转移、这种共生体在采采蝇中诱导细胞质不亲和性的能力,以及如何利用沃尔巴克氏体共生关系开发新的环保疾病控制工具。
