Purpose Acanthamoeba castellanii is an important opportunistic human protozoal pathogen that can cause both skin, ocular and brain infections. Recent studies have established that brews and solvent extract (SE) of green tea ( Camellia sinensis ) can inhibit the growth and encystation of A. castellanii . Here we characterized those growth and encystation inhibitions. Methods Herein, we characterize of the morphological and chem...

Summary We have reported previously that copper I and II ionic species, and superoxide but not Fenton reaction generated hydroxyl radicals, are important in the killing mechanism of pathogenic enterococci on copper surfaces. In this new work we determined if the mechanism was the same in non‐pathogenic ancestral (K12) and laboratory (DH5α) strains, and a pathogenic strain (O157), of Escherichia coli . The pathogenic strain exh...
