Introduction: In today’s world, with the expansion of electronic technologies and equipment generating electromagnetic fields, humans and other living organisms are continuously exposed to these fields. This exposure can have significant biological effects on the growth and function of living organisms. This study aimed to evaluate the effects of alternating magnetic fields with different intensities and frequencies on the growth of Escherichia coli (E. coli), a Gram-negative bacterium, and Staphylococcus aureus (S. aureus), a Gram-positive bacterium.
Methods: This study investigated the effects of alternating magnetic fields with intensities of 1 and 2 millitesla and frequencies of 50, 75, 100, and 150 Hz on the growth of Escherichia coli and Staphylococcus aureus. The standard plate counting technique was used for this purpose. Samples were incubated at 37°C for 24 hours, and the number of colonies was counted as colony-forming units per milliliter (CFU/ml).
Results: The results showed that the number of Escherichia coli colonies significantly increased under the influence of magnetic fields compared to the control group (P < 0.05). In contrast, the number of Staphylococcus aureus colonies significantly decreased after exposure to the magnetic field (P < 0.05).
Conclusions: The results of this study indicate that alternating magnetic fields can have different effects on the growth of various bacteria. According to these findings, a decrease in the number of colonies was observed in Staphylococcus aureus due to the magnetic field, while an increase in the number of colonies was observed in Escherichia coli. These findings could be used in the development of new methods for controlling bacterial growth and in biotechnological applications.
