Photoinactivation of gram-positive and gram-negative microorganisms by cationic porphyrins
Keywords:
Cationic porphyrins – photodynamic inactivation – Gram-positive and Gramvnegative bacteria
Abstract
The effectiveness of new cationic porphyrins and their Zn-complexes (6 compounds) was tested against two Gram-positive (St. aureus and St. epidermidis) and two Gram-negative (E. coliK-12 and Salmonella sp.) bacteria. It is shown that cationic porphyrins have high photodynamic activity against of both types of microorganisms.
