Application of laser inhibits the bacterial growth contrasting to the Antibiotics

Abstract :

 Respectably studies provided a unique examples of most frequent types of germs such as E. coli and S. aureus as results

to their presence in large quantities around the human being as normal flora to human intestinal canal and their foods
specially salty dairy, causes various disease such as diabetic foot. Laser uses in medical procedures mostly are therapeutic, diagnostic, and
imaging application. Like important and highly sensitive procedures of opthalometery surgery in corrections and lizak, dentistry, dermatology,
and close the bleeding of the tiny vessels within the operations. Samples collected from forty patients suffered different injury inflammations,
using sterile cotton, the samples diagnosed depending on a number of morphological examinations, biochemical tests and culturing on selective
media,. The bacterial isolates obtained including the followings: Staphylococcus aureus (24.68 %) , Escherichia coli (21.31 %),The sensitivity
of the bacterial isolates before irradiation to a number of antibiotics were examined , they all gave high resistance to the antibiotics, except two
types (Streptomycin & Ciprofloxacin) , which the bacterial isolates were sensitive to. The bacterial isolates irradiated with laser using
wavelengths (770, 880, and 990 nm) to increase their sensitivity reaching to a step of attenuating or killing the bacteria with increasing exposure
times. Laser effect on the bacterial isolates showed a significant decrease in the viability of the bacteria of all species when the dose was
increased, where occur killing the bacteria after 20 min and more of laser dose. It is likely to be increasing the motility of antibiotics molecules by
the radiation heat rather than direct effects. Increasing the motility of water and media molecules by the radiation heat rather than direct effects is
well known drama of irradiation through free radical formation process as hydroxyl and superoxide. The results encourage for more work to seek
the interpretation of free radical formation and irradiation to give clear direct evident in using laser as disinfectant.
