Native bacteria block Wolbachia from being passed to mosquito progeny

11 agosto 2014

Native bacteria living inside mosquitoes prevent the insects from passing Wolbachia bacteria — which can make the mosquitoes resistant to the malaria parasite — to their offspring, according to a team of researchers. The team found that Asaia, a type of bacteria that occurs naturally in Anopheles mosquitoes, blocks invasion of Wolbachia into the mosquitoes’ germlines — the cells that are passed on through successive generations of an organism — thus stopping the insects from transmitting Wolbachia to their offspring.
