Identification of Wolbachia--host interacting factors through cytological analysis.

Manipulation of host reproduction and efficient maternal transmission have facilitated the global spread of Wolbachia through millions of insect species. Cytological studies of the most common Wolbachia-induced phenotype, cytoplasmic incompatibility (CI), demonstrate that Wolbachia induce CI by altering host cell cycle timing. Cytological analyses also suggest that microtubules and motor proteins may play a role in the maternal and somatic transmission of Wolbachia.
