Sonic stimulation at certain frequencies can confer limited protection on nematode host infected with Serratia marcescens

Abstract

Different mono-frequency and poly-frequency sounds were investigated for their possible therapeutic effect on infected worm (Caenorhabditis elegans) population. Sound corresponding to the frequency of 700 Hz and 2,000 Hz were found to confer 11-27% survival benefit on worm population challenged with multi-drug resistant gram-negative bacterial pathogen Serratia marcescens.
