Fig. 5From: Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry traces the geographical source of Biomphalaria pfeifferi and Bulinus forskalii, involved in schistosomiasis transmissionThe tree was based on a nucleotide sequence of a 710 bp region of the cytochrome c oxidase subunit I (COI) gene (a) and the 550-bp 16S region (b), constructed using Kimura’s two-parameter distance-based maximum likelihood method with MEGA 7. The values on the branches are bootstrap support values based on 1000 replications. The branches have a pictogram corresponding to the bootstrap values. The identity of each taxon is encoded in bold with the pictogram according to the speciesBack to article page
