FIG 2.

Differences in attachment numbers between S. Typhimurium ATCC 14028 (ST) and L. monocytogenes ATCC 7644 (LM) when present individually and at different initial S. Typhimurium/L. monocytogenes inoculum ratios (0.428, 1, or 2.333) on BC composites and abiotic surfaces. SSC, stainless steel coupons. Different uppercase letters indicate significant differences between attachment surfaces, whereas different lowercase letters indicate significant differences between individual attachment and attachment at different initial inoculum ratios for the same attachment surface (two-way ANOVA and Tukey's pairwise comparison, P < 0.05).
