| Abstract: | Nd-YAG laser radiation of 1.06 or 1.32 μ wavelength killed a proportion ofStaphylococcus aureus andEscherichia coli cells at power densities of 40 to 80 W/cm2 and effected a 100% kill of these cells at a power density of 1000 W/cm2. In blood agar, the radiation of 1.06 μ produced bactericidal effects to a depth twice that of the radiation of 1.32 μ. Laser radiation of these wavelengths did not cause elimination of R plasmids and had no effect on the antibiotic resistance of bacteria.
