FIG 2.

Time-kill kinetics of TRP for C. jejuni under nongrowing conditions. (A) Growth curves of the C. jejuni NCTC 11168 and 81-176 strains in MH broth at different temperatures (4, 15, 25, and 37°C) under microaerophilic conditions. (B) Viable cell counts of the C. jejuni NCTC 11168 and 81-176 strains in PBS at different temperatures (4, 15, 25, and 37°C) under aerobic conditions. The TRP concentrations were set at 0, 0.1, 1, 10, and 100 μM. The data are shown as the means and SDs of the results from three independent experiments. Asterisks indicate statistically significant differences from the control (PBS without TRP) by Student’s t test (*, P < 0.05; **, P < 0.01) at the same time point.
