Abstract

Abstract Summary

Overview

Previous studies on the effects of magnetic fields on microorganisms often involved different species, whereas this study focuses on different strains within the same species.

Methodology and Experimentation

The study investigates the impact of rotating magnetic fields (RMF) of 5 and 50 Hz on eight bacterial species with multiple strains per species, including a homogeneous group of Staphylococcus aureus.

Findings

  • The influence of RMF varied across strains more significantly than across the two different frequencies used.
  • Responses to RMF ranged from positive (increased growth and metabolic activity) to negative (reduced growth and metabolic activity), indicating a health risk related to electromagnetic fields, as well as the complex nature of biological responses to RMF.
  • Intraspecies variability played a significant role in the observed effects, emphasizing the adaptive or strain-specific responses under identical RMF conditions.

Conclusion

The study underscores the importance of genetic variability among bacteria when assessing the impacts of RMF, suggesting potential broader implications for understanding EMF effects on other organisms, including possible health risks in humans.
