In our previous study, we found that Pseudomonas aeruginosa is more sensitive to Ar-laser than Esherichia coil and Staphylococcus aureus. In present report we applied Ar-laser to various kinds of bacteria. 1ml (106-107 celis/ml) bacteria solution was mixed into Muller-hinton medium. And after 30min laser irradiation of 20, 40, 60mw, they were incubated at 37°C for 48hours.
The result was that P. aeruginosa, P, fluorescens, E. coli, S. enterotidis, P. mirabiris, M. morganii, are sensitive to Ar-laser photoirradiation, but the others are not sensitive at that power.
