Effects of Echinococcus multilocularis infection on the metabolic composition of mouse urine were assessed. 10 mice were perorally (intragastic gavage) infected with 400 E. multilocularis eggs each. 12 control mice were mock infected. Urine samples were collected 11 weeks post infection. After this incubation period urine samples were analyzed by nuclear magnetic resonance spectroscopy (NMR: 1D 1H).

Urine samples were centrifuged at maximum speed for 10 min at 4 °C. 35 µl of each sample supernatant were mixed with 35 µl sodium phosphate buffer (D2O:H2O, v/v, 9:1; pH=7.4; 0.01% trimethylsilylpropanoic acid (TSP); 3 mM sodium-azide), vortexed and centrifuged. 60 µl of each sample were transferred into a 1.7 mm diameter NMR tube. 1H NMR spectroscopy was recorded at 300 K on a Bruker DRX 600MHz NMR spectrometer (Bruker Biospin; Rheinstetten, Germany) at 600.29 MHz. Each spectrum was acquired with 2.73 sec acquisition time for 128 scans (spectral width = 20.2 ppm) with a standard pulse sequence (recycle delay-90°−t1-90°-tm-90°-acquire free induction decay (FID)).
