However, there are have been reports that recently reveals the presence of this endosymbiont in this mosquito vector. With this, our study presents additional support of Wolbachia infection in Ae. aegypti by screening field-collected adult mosquitoes using Wolbachiaspecific 16S rDNA and its surface protein (wsp) makers under optimized PCR conditions. From a total of 672 Ae. aegpyti adult mosquito samples collected in Metropolitan Manila, Philippines, 113 (16.8\%) and 89 (13.2\%) individual mosquito samples were determined to be Wolbachia infected using the wsp and 16S rDNA markers, respectively. The Ae. aegpyti wsp sample sequences were similar or identical to five known Wolbachia strains belonging to supergroups A or B while majority of 16S rDNA sample sequences were similar to strains belonging to supergroup B. Overall, 80 (11.90\%) individual mosquito samples revealed to show positive amplifications in both markers and 69.0\% showed congruence in supergroup identification (supergroup B). Our findings illustrate that the infection status of Wolbachia in Ae. aegypti may appear common than previously recognized.}, URL = {https://www.biorxiv.org/content/early/2018/09/08/408856}, eprint = {https://www.biorxiv.org/content/early/2018/09/08/408856.full.pdf}, journal = {bioRxiv} }
