Abstract: 

The in vitro effectivity of cranberry derived proanthocyanidins (PACs) for the mitigation of kidney cell
infection by selected uro- and entero-pathogens is examined with an adhesion/invasion assay and confocal
microscopy. This study demonstrates that PACs effectively reduce invasion of canine kidney cells by
pathogenic bacteria: Escherichia coli CFT073 and O157:H7, Enterococcus faecalis 29212, and Pseudomonas
aeruginosa 10145. These effects demonstrate the potential for cranberry derived PACs as a useful tool in
the prevention of kidney infection
