FIG 3.

AMP transcripts are elevated in R. typhi-infected KC167 cells. Shown are results of an RT-qPCR analysis of AMP gene expression in cDNAs prepared from KC167 cells. Transcripts were measured in uninfected cells and in cells infected with E. coli or R. typhi for 4 h or in cells treated with heat-killed R. typhi for 4 h. The data are normalized to the housekeeping genes Actin and Rpl32 and the uninfected control. Error bars indicate SEMs. *, P < 0.05; **, P < 0.01; ***, P < 0.001 (relative to uninfected cells; Student's two-sided t test).
