title: Reversing Wolbachia-based population replacement.
abstract: Genetic manipulation that reduces the competence of a vector population to transmit pathogens would provide a useful tool to complement current control strategies, which are based primarily on the reduction/exclusion of vector populations and the prophylactic/therapeutic treatment of the vertebrate host population. Genetic drive is an important component of vector population replacement strategies, facilitating the replacement of natural populations with a genetically modified population. Genetic drive is reviewed here, emphasizing strategies that would employ infections of intracellular Wolbachia bacteria as a vehicle for population replacement. Also discussed are strategies for the retarding, arresting or reversing of Wolbachia-based population replacement. These strategies are based upon altering the conditions required for transgene invasion and are a prudent safeguard, should unexpected detrimental effects become associated with transgene spread.
