Abstract
Wolbachia is an endosymbiotic bacterium that naturally infects many insect species, including mosquitoes that transmit human diseases. Wolbachia strains have been shown to inhibit the transmission of both arboviruses and malaria Plasmodium parasites. The existence of natural strains in wild Anopheles (An.) mosquitoes, the vectors of malaria parasites, in an endosymbiotic relationship is still to be fully determined. Although Wolbachia has been reported to be present in wild populations of the An. gambiae complex, the primary vectors of malaria in Sub-Saharan Africa, Wolbachia DNA sequence density and infection frequencies are low. As most studies have used highly sensitive nested PCR as the only detection method, more robust evidence is required to determine whether Wolbachia strains are established as endosymbionts in Anopheles species. Techniques such as fluorescent in situ hybridization, microbiome sequencing, and Wolbachia whole genome sequencing have provided concrete evidence for genuine Wolbachia strains in two mosquito species: An. moucheti and An. demeilloni. In this chapter, the current methodology used to determine if resident strains exist in Anopheles mosquitoes will be reviewed, including both PCR- and non-PCR-based protocols.
