(a) Relative abundance of Klebsiella, Rickettsia, Sodalis, and Spiroplasma in whole wild tsetse flies. (Gmed: G. medicorum; Gms: G. morsitans submorsitans; Gpg: G. p. gambiensis; Gt: G. tachinoides). (b) Weighted Unifrac Principal Component Analysis of 16 S rRNA gene MiSeq data. Each data point represents an individual tsetse fly and is coloured according to Glossina species. Convergent evolution between the primary endosymbiont Wigglesworthia and its host due to direct vertical transmission generates a tsetse species-clustering pattern that simplifies the detection of emergent taxa such as Spiroplasma and Rickettsia. All gut samples originated from the study by Aksoy et al. in 2014, and whole samples were collected in Burkina Faso. (Gmm: Glossina morsitans morsitans; Gff: G. fuscipes fuscipes; Gmed: G. medicorum; Gms: G. morsitans submorsitans; Gpal: G. pallidipes; Gpg: G. palpalis gambiensis; Gt: G. tachinoides).
