Abstract
This study was conducted in Tikrit Teaching Hospital on 73 patient with wounds. 30 (41%) isolates of Pseudomonas aeruginosa were obtained from these patients. 20 isolates were randomly selected for the present study. The present study revealed a significant effect of low-power diode laser light with photochemical agent povidone-iodine (PVP-I ) on elastase production and all the tested isolates were elastase-negative after exposure.
