“…It has been reported that electromagnetic field (EMFs) can either negatively [3][4][5][6] or positively [5,7,8] affect cell growth and viability, as well as bacterial sensitivity to antibiotics, depending on its physical parameters, such as frequency, exposure time, intensity and magnetic flux density and bacterial strain. The non-thermal effects of Wi-Fi exposure on different strains of bacteria have been studied [5][6][7][8][9][10][11]. Overall, the effects of EMFs on the biological systems have been investigated in several studies [1,9].…”

Background: Overuse of antibiotics is a cause of bacterial resistance. It is known that electromagnetic waves emitted from electrical devices can cause changes in biological systems. This study aimed at evaluating the effects of short-term exposure to electromagnetic fields emitted from common Wi-Fi routers on changes in antibiotic sensitivity to opportunistic pathogenic bacteria. Materials and Methods: Standard strains of bacteria were prepared in this study. Antibiotic susceptibility test, based on the Kirby-Bauer disk diffusion method, was carried out in Mueller-Hinton agar plates. Two different antibiotic susceptibility tests for Staphylococcus aureus and Pseudomonas aeruginosa were conducted after exposure to 2.4-GHz radiofrequency radiation. The control group was not exposed to radiation. Results: Our findings revealed that by increasing the duration of exposure to electromagnetic waves at a frequency of 2.4 GHz, bacterial resistance increased against S. aureus and P. aeruginosa, especially after 24 hours (P<0.05). Conclusion: The use of electromagnetic waves with a frequency of 2.4 GHz can be a suitable method for infection control and treatment. [GMJ.2020;9:e1580]

“…Non-ionizing electromagnetic radiation affects biological system through either thermal or non- thermal effects [1,2]. Many scientific studies have investigated biological effects of electromagnetic fields (EMF) [1-3]. Non-thermal EMF induced different responses on bacteria depending on frequency intensity, exposure time and organism model [4].…”

Background:The radiation emitted from electromagnetic fields (EMF) can cause biological effects on prokaryotic and eukaryotic cells, including non-thermal effects. Objective: The present study evaluated the non-thermal effects of wireless fidelity (Wi-Fi) operating at 2.4 GHz part of non-ionizing EMF on different pathogenic bacterial strains (Escherichia coli 0157H7, Staphylococcus aureus, and Staphylococcus epidermis). Antibiotic resistance, motility, metabolic activity and biofilm formation were examined. Material and Methods: In this case-control, a Wi-Fi router was used as a source of microwaves and also bacterial cells were exposed to Wi-Fi radiation continuously for 24 and 48 hours. The antibiotic susceptibility was carried out using a disc diffusion method on Müller Hinton agar plates. Motility of Escherichia coli 0157H7 was conducted on motility agar plates. Cell metabolic activity and biofilm formation were performed using 3-(4, 5-Dimethylthiazol-2yl)-2, 5-diphenyltetrazolium bromide (MTT) assay and crystal violet quantification, respectively. Results:The exposure to Wi-Fi radiation altered motility and antibiotic susceptibility of Escherichia coli 0157H7. However, there was no effect Wi-Fi radiation on antibiotic susceptibility of Staphylococcus aureus and Staphylococcus epidermis. On the other hand, the exposed cells, as compared to the unexposed control, showed an increased metabolic activity and biofilm formation ability in Escherichia coli 0157H7, Staphylococcus aureus and Staphylococcus epidermis. Conclusion:These results proposed that Wi-Fi exposure acted on bacteria in stressful manner by increasing antibiotic resistance and motility of Escherichia coli 0157H7, as well as enhancing biofilm formation by Escherichia coli 0157H7, Staphylococcus aureus and Staphylococcus epidermis. The findings may have implications for the management of serious diseases caused by these infectious bacteria.

Abstract-This paper reviews some papers discussing the effect of radio frequency (RF) on human cells and proposal toward better experimental work. A prototype of radio frequency absorber box with air ventilation was introduced in order to investigate its effect on human cells. A few factors that contribute to the effect of radiation is recognized and studied. The success of our proposed iron mesh box to absorb RF signals was demonstrated wherein normal level of RF radiation is achieved within the closed system of the incubator. The mesh box has been shown to have absorbed at least 88.11% of total RF generated.
