Sonic stimulation, and low power microwave radiation can modulate bacterial virulence towardsCaenorhabditis elegans

Caenorhabditis elegans worms infected with different pathogenic bacteria were subjected to sonic treatment to investigate whether such sound treatment can exert any therapeutic effect on the infected worms. Sonic therapy corresponding to 400 Hz, and the divine sound ‘om’ were found to confer protective effect on this nematode worm in face of bacterial infection, particularly that caused by Serratia marcescens or Staphylococcus aureus . The observed effect seemed to occur due to influence of sound on bacteria, and not on the worm. In addition to this, effect of microwave exposure on bacterial virulence was also investigated, wherein microwave exposure was found to reduce virulence of S. aureus towards C. elegans .
