<p>Typical 500 MHz <sup>1</sup>H (CPMG) NMR spectra of plasma obtained from a non-infected SD rat (P<sub>A</sub>) and a rat infected with <i>K. pneumoniae</i> for 8 hours (P<sub>B</sub>). The region of δ 5.0–9.0 in the blood plasma spectra was vertically expanded 16 times compared with the region of δ 0.5–4.5; Representative 600 MHZ <sup>1</sup>H NMR spectra of urine samples obtained from a non-infected SD rat (U<sub>A</sub>) and a rat infected with <i>K. pneumoniae</i> for 8 hours (U<sub>B</sub>).
