MODULATION OF STAPHYLOCOCCUS AUREUS BIOFILM BY ELECTROMAGNETIC RADIATION

Mobile communication systems are undoubtedly an environmental source of electromagnetic radiation (EMR). Although the direct health effect a cell phone to human is still elusive, unicellular organisms rather apparent. The aim this study was examine effects EMR on development bacterial biofilm. Microtitration plates with four strains Staphylococcus aureus were exposed field frequencies 1-5 GHz, which used in mobile phones. results showed mostly inhibition biofilm activity at 1, 2 and 3 however significant stimulation occurred 4 5 GHz. Our observations demonstrate that exposure produced modulation biofilms, very important commensal pathogen bacteria.
