Derivatives of cranberry fruit, predominantly condensed
tannins called proanthocyanidins (PACs) have been reported to interfere with bacterial adhesion, but the
effects of PACs and other tannins on bacterial motilities remain largely unknown. In this study, we investigated
whether cranberry PAC (CPAC) and the hydrolyzable tannin in pomegranate (PG; punicalagin) affected the
levels of motilities exhibited by the bacterium Pseudomonas aeruginosa
