Fig. 2: Box plots for transfer rates of multi-species biofilms (F96, F107 and F168) after contact clustering.
From: A formal analysis of Listeria monocytogenes cross-contamination dynamics in multi-species biofilms

The 25 contacts were clustered (1–3) based on the absence of significant differences in experimental values (p > 0.05); the contacts included in each cluster are listed in Table 2. Different letters in each cluster indicate significant differences between biofilms (p < 0.05).
