Abstract

Drosophila simulans strains infected with three different Wolbachia strains were generated by experimental injection of a third symbiont into a naturally double-infected strain. This transfer led to a substantial increase in total Wolbachia density in the host strain. Each of the three symbionts was stably transmitted in the presence of the other two. Triple-infected males were incompatible with double-infected females. No evidence was obtained for interference between modification effects of the different Wolbachia strains in males. Some incompatibility was observed between triple-infected males and females. However, this incompatibility reaction is not a specific property of triple-infected flies, because it was also observed in double-infected strains.

摘要

通过将第三种共生菌实验性注射到自然双重感染的品系中，培育出感染三种不同沃尔巴克氏体菌株的拟果蝇品系。这种转移导致宿主品系中沃尔巴克氏体的总密度大幅增加。这三种共生菌中的每一种在另外两种共生菌存在的情况下都能稳定传播。三重感染的雄性与双重感染的雌性不相容。未获得不同沃尔巴克氏体菌株对雄性修饰作用之间存在干扰的证据。在三重感染的雄性和雌性之间观察到了一些不相容性。然而，这种不相容反应并非三重感染果蝇的特异性特征，因为在双重感染的品系中也观察到了这种情况。
