Abstract :
Background: The increasing use of telecommunication devices such as Wi-Fi
modems and mobile phones in the recent years can change the cellular structure of
microorganisms so the generation of electromagnetic waves has led to concern in the
community whenever be exposed to these fields and may have harmful effects on
human health.
Material and Methods: In this experimental study, standard strains of
bacteria were prepared on Mueller-Hinton agar for bacterial growth to obtain 0.5
McFarland turbidity (1.5 × 108 CFU) of bacteria. Antibiotic susceptibility test using
the Kirby-Bauer disk diffusion method was done. For Staphylococcus aureus and
Pseudomonas aeruginosa, antibiotics susceptibility test was conducted. The test
group was exposed to electromagnetic waves emitted by mobile phone simulator
with a frequency of 900 MHz and the control group were not exposed.
Results: The results revealed that increasing duration of exposure to electromagnetic
waves emitted by the mobile simulators with a frequency of 900 MHz especially
after 24 h of exposure, can increase bacterial resistance in S. aureus, and P.
aeruginosa.
Conclusion: Several factors can cause bacterial resistance against antibiotics.
One of these factors is the electromagnetic waves emitted from mobile simulator
with a frequency of 900 MHz, which can increase the permeability of the cell wall of
bacteria.
