Staphylococcus aureus, one of the microflora in a
human external auditory canal (EAC) is frequently exposed to highfrequency
electromagnetic field (HFEMF) generated by mobile
phones. It is normally nonpathogenic but in certain circumstances, it
can cause infections. This study investigates the changes in the
physiology of S. aureus when exposed to HFEMF of a mobile
phone. Exponentially grown S. aureus were exposed to two
conditions of EMF irradiation (standbymode and oncall mode) at
four durations; 15, 30, 45 and 60 min. Changes in the viability and
biofilm production of the S. aureus were compared between the two
conditions of exposure. EMF from the standbymode has enhanced
the growth of S. aureus but during oncall, the growth was
suppressed. No significant difference in the amount of biofilm
produced in both modes of exposure was observed. Thus, HFEMF
of mobile phone affects the viability of S. aureus but not its ability to
produce biofilm.
