Global metabolic responses of mice to Trypanosoma brucei brucei infection - PubMed

Typical 600 MHz ¹H NMR spectra of urine obtained from a mouse at preinfection (A), at 14 days postinfection (B), and at 28 days postinfection (C). The spectra in the aromatic region (δ 6.5–8.0) were magnified 4 times compared with the region δ 2.3–4.3, whereas the region δ 0.7–2.3 was magnified twice.
