| Abstract | ||
| This study was carried out in laboratories of college sciences/ Tikrit University to investigate effect of visible diode laser with wave length (600) nanometer and Infra Red Diode laser with wave length (800) nanometer on some types of bacteria that isolated from different infects of human skin. All isolates that exposed to laser irradiation were E.coli, Staphylococcus aureus, Staphylococcus saprophyticus, Pseudomonas aeruginosa. Bacterial growth differ according to laser’s ray type that used in the irradiation. Most bacteria effected with visible laser ray at 15 seconds were E.coli and Staphylococcus aureus, the growth rate was 40%, while all bacterial isolates were effected with infra red ray, the growth rate of bacterial isolates was 40% except E.coli the growth was absent at 10 and 15 seconds. Sensitivity test was done after and before irradiation with two type of laser diode rays to all bacterial isolated and the results were different according to type and time of the laser radiation. Staphylococcus aureus became sensitive to Amikacin, Vancomycin and Oxacillin antibiotics after irradiation with visible laser diode for (5,10 and 15) seconds, while sensitivity of Staphylococcus saprophyticus was increased to Vancomycin also E.coli became sensitive to Vancomycin sensitivity increased to Oxacillin at 5 and 15 seconds. Results was different when the bacterial isolated irradiated to Infra Red laser diode. Staphylococcus aureus became to Amikacin and Vancomycin but the sensitivity of Staphylococcus saprophyticus to all antibiotics not different just become more resistant to Vancomycin and Oxacillin while E.coli became sensitive to Ciprofloxacin, Amikacin, Vancomycin and Oxacillin with irradiation at 5 seconds. The sensitivity of Pseudomonas aeruginosa increased to Amikacin after irradiation with visible and Infra-Red laser diode for 15 seconds. | ||
