Summary of metabolites in serum.

aArrows (↓ and ↑) represent a decrease or increase in metabolite levels with significant changes in O. tsutsugamushi-infected mice compared with control mice on day 4 and/or day 7. bNo significant change. Levels were estimated based on intensities of 1H-NMR spectra of serum following spectral normalization. s, singlet; d, doublet; q, quartet; t, triplet, m, multiplet; br, broad; *, p<0.05.
