FIG. 3.

Changes in viable numbers and heat resistance of C. jejuni NCTC 11351 during extended incubation in stationary phase. Cells were grown to stationary phase in BBFBP under microaerobic conditions at 39°C. Samples were removed at intervals for the determination of viable counts (●) and survival after a heat challenge at 50°C for 75 min (⋄). Results from two representative experiments are shown. Data in panel a are from a single determination at each time interval, and those in panel b are the means of duplicates.
