The effect of electromagnetic fields on the interaction between the antibiotics erythromycin and bacterial species Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) are determined by its influence on the growth rate of bacterium. Previous studies have shown the electromagnetic field effects were on effectivity of erythromycin on E. coli. Erythromycin has been studied in detail previously. Experimental samples of E. coli and S. aureus were prepared in varying environments of magnetic field. Measurements of optical density were done to determine the growth rates and behavior of bacteria after its exposure to the magnetic field. Experiment data sets were used to visualize the response of bacteria to antibiotics in different concentrations. It has been shown clearly that the perturbative effect of the magnetic field reduce the growth rate significantly for lower concentrations of antibiotics. For higher concentration of 200 microgram/milliliter the low magnetic field effect is totally suppressed.
