Abstract: The subversive symbiont Wolbachia is an extraordinary bacterium, widely studied because of its unique biology. It forms symbiotic intracellular inherited infections in many insects and other invertebrates, and by blocking egg fertilization by host sperm yet ‘rescuing’ infected eggs to develop normally it gives a reproductive advantage to infected females. Wolbachia can rapidly invade an uninfected population, so can potentially introduce deleterious genes into insects as means of disease control. A new aspect of these effects on host phenotype is reported this week, providing an insight into the genetic mechanism by which Wolbachia causes incompatibility between crossing types in the Culex mosquitoes, including the filariasis vector.
