ABSTRACT
The emergence of pathogens in today's world has increased the need for new technologies. The main focus of this work was to study the biological effect of magnetic fields, as a component of the non-ionizing radiation on the Pathogenic microorganism Escherichia coli. Antibiotic resistant E. coli were isolated and cultured. Equal volumes of E.coli suspension were exposed to Isotopes Applications Division, square amplitude modulated waves [SAMW] from generators Atomic Energy Authority with constant carrier frequency of 10 MHz and amplitude 0.5 Vpp. The results indicated that exposure of E.coli samples to 0.5 Hz magnetic field caused suppressive effect on the growth and the number of cells. Further changes in the antibiotic sensitivity were observed after exposure where E. coli cells became more sensitive to certain antibiotics as netilmycin, amikacin and cefepime. Meanwhile, no change in the size of DNA fragments was observed. According to the accumulated data. The exposure to extremely low frequency electromagnetic field induced change in the antibiotic sensitivity and inhibition of E. coli growth, suggesting its potential for application as a method for controlling microbial population growth within a variety of environments
