Influence of Mobile Phone Electromagnetic Field Exposures on Pseudomonas Aeruginosa and Staphylococcus Aureusinvitro

Abstract

Background: Mechanism underlying the lethal effect of microwave radiation on microorganisms are yet to be discovered. Some researchers hypothesized that electromagnetic waves can increase the target temperature and destroy life. Objectives: The aim of this study was to determine the impact of cell phone radiation on bacteria that cause otitis media. Materials and Methods: Two bacterial isolates were selected from cases of inflammation of the middle ear (otitis media). Pseudomonas aeruginosa and Staphylococcus aureus, isolates were exposed to electromagnetic waves emitted from mobile. After the incubation period, the absorbance was measured to determine the degree of turbidity by using spectrophotometer on the wavelength 400nm. Results: It was found that is no effect of mobile radiation up to six minutes of exposure to both bacterial Species, but influence began after the six minutes and increased influence directly proportional to the time. Effective dose 50 of Staphylococcus aureus was 11.5 minutes while for Pseudomonas aeruginosa was 14.2 minutes. Conclusions: The radiofrequency of cell phone effects on the bacteria depend on the following factors: the exposure time to mobile radiation, water content and increasing temperature, breaking protein molecule.
