A rod-shaped bacterium has been isolated that kills male eggs of the wasp Nasonia vitripennis, a pupal parasite of flies. Only some wasps of this species express this son-killer trait, and these wasps have bacterial infections in various organs. The bacterium was isolated from son-killer wasp tissue and from the hemolymph of fly pupae parasitized by wasps expressing the son-killer trait. Bacteria are apparently transferred to parasitized fly pupae during wasp oviposition, and developing wasp offspring are subsequently infected perorally. Sex-ratio distortion by microorganisms is found in a variety of plants and animals. The infectious peroral transmission of this trait variety of plants and animals. The infectious peroral transmission of this trait is in contrast to the typical pattern of cytoplasmic inheritance of sex-ratio distortion in these other systems.
已分离出一种杆状细菌，它能杀死丽蝇蛹集金小蜂的雄性卵，丽蝇蛹集金小蜂是苍蝇的一种蛹寄生虫。该物种中只有一些黄蜂表现出这种杀子特性，并且这些黄蜂的各个器官都受到细菌感染。这种细菌是从具有杀子特性的黄蜂组织以及被此类黄蜂寄生的蝇蛹血淋巴中分离出来的。细菌显然是在黄蜂产卵时转移到被寄生的蝇蛹中，随后发育中的黄蜂后代经口感染。微生物导致的性别比例畸变在多种植物和动物中都有发现。这种特性的传染性经口传播与这些其他系统中性别比例畸变的典型细胞质遗传模式形成对比。
