In the last years, antimicrobial photodynamic therapy (aPDT) has been considered as one
important alternative to be used in antimicrobial treatments. In the present work we report the
first photoinactivation of Salmonella enterica serovar Typhimurium (Salmonella
Typhimurium) by cationic free-base meso-tetra-(phenyl) porphyrin and its Zn (II) complex
containing peripheral Ru (II)-bipyridyl complexes. Bacterial inoculum (10 7 CFU mL-1) was
incubated with the porphyrins (25 μM) with an irradiation system containing a halogen lamp …
