Fig. 2From: Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry traces the geographical source of Biomphalaria pfeifferi and Bulinus forskalii, involved in schistosomiasis transmissiona Representative MS profiles of Bu. forskalii from Diourbel (1–2) and SRD (3–4) and Bi. pfeifferi from South-Eastern Senegal Wild strain (5, 6), lab strain (9–10) and Bi. pfeifferi from SRD (7–8) as a function of geographical location using FlexAnalysis v.3.3 software. au: arbitrary units; m/z: mass-to-charge ratio. b MALDI–TOF MS distinction of snail spectra using the feet shown on the PCA with ClinProTools software: Bu. forskalii (red crosses; ten specimens); Bi. pfeifferi (green circles; ten specimens) and out-group (Planorbella spp.) (blue squares; one specimen)Back to article page
