Comment; 900 & 1800 MHz had little effect on S. aureus, S. Epidermidis & P. aeruginosa. OK, what about higher order eukaryotes such as mammals?
This study was aimed to evaluate the impact of high frequency electromagnetic ﬁelds (HF—EMF at 900 and1800 MHZ) on DNA, growth rate and antibiotic susceptibility of S. aureus, S. epidermidis, and P. aeruginosa.
In this study, bacteria were exposed to 900 and 1800 MHZ for 2 h and then inoculated to new medium when their growth rate and antibiotic susceptibility were evaluated. Results for the study of bacterial DNA unsuccessful to appearance any difference exposed and non—exposed S. aureus and S. epidermidis.
Exposure of S. epidermidis and S. aureus to electromagnetic ﬁelds mostly produced no statistically significant decrease in bacterial growth, except for S. aureus when exposure to 900 MHZ at 12 h. Exposure of P. aeruginosa to electromagnetic ﬁelds at 900 MHz however, lead to a signiﬁcant reduction in growth rate, while 1800 MHz had insigniﬁcant effect. With the exception of S. aureus, treated with amoxicillin (30 pg) and exposed to electromagnetic ﬁelds, radiation treatment had no signiﬁcant effect on bacterial sensitivity to antibiotics.
