Typical 600 MHz ¹H NMR spectra of urine obtained from an uninfected (A) and a S. mansoni -infected (B) mouse at day 53 post-infection. A 3-D PCA trajectory scores plot (C) derived from urinary spectra of both control (black), S. mansoni-infected mice at early stage (13-41 days post-infection, blue) and these infected mice at the late stage (48-73 days post-infection, red). D and E represent 2-D PCA scores plots constructed from first and second PCs (D), and first and third PCs (E), respectively.
