Wolbachia Infection in Iranian Malaria Vectors: Prevalence and Biocontrol Implications.
Wolbachia-based vector control is an emerging tool in malaria prevention research. This study evaluates Wolbachia infection in Iranian mosquitoes, focusing on seven known malaria vectors. Mosquitoes were collected from nine provinces of Iran (2016-2019), and Wolbachia infection status was analysed via PCR targeting eight genes: wsp, gatB, ftsZ, dnaA, groEL, gltA, CoxA and fbpA. We examined 1094 specimens from seven malaria vectors (Anopheles stephensi Liston, 1901; Anopheles culicifacies s.l. James, 1901; Anopheles fluviatilis s.l. James, 1902; Anopheles maculipennis s.l. Meigen, 1818; Anopheles sacharovi Favr, 1903; Anopheles dthali Patton, 1905; Anopheles superpictus s.l. Grassi, 1899), four non-malaria vectors (Anopheles mongolensis Linton, Lee and Curtis, 2005; Anopheles hyrcanus Pallas, 1771; Anopheles claviger Meigen, 1804; Anopheles turkhudi Liston, 1901) and three Culex species (Culex pipiens Linnaeus, 1758; Culex perexiguus Theobald, 1903; Culex theileri Theobald, 1903). PCR revealed Wolbachia DNA exclusively in An. dthali and Culex species, with infection rates of 73.4% for An. dthali and 77.78%-96.77% for Culex, notably higher in males. Wolbachia was detected in all regions except one in the north. Phylogenetic analysis revealed Wolbachia strains in An. dthali and Culex belong to supergroup B, closely related to strains in An. moucheti and An. demeilloni. This suggests broader applications for biocontrol strategies. The high Wolbachia prevalence in An. dthali is promising for malaria prevention. Future research should confirm cytoplasmic incompatibility and explore wAdth's potential to block malaria transmission.
