PACC1 and bacterial urinary tract infection: The results of this PCA analysis that are depicted in Figure 2 show that the antiviral activity of PAC-As is correlated primarily to the presence of low-degrees of A-type PAC polymerization (from monomers to tetramers), whereas the antibacterial activity (primarily against bacteria that cause Urinary Tract Infections, UTI) was associated with the presence of dimeric and trimeric PAC-A.
