Serratia marcescens (S. marcescens) has become an important nosocomial pathogens and increased resistant isolates were reported. The current study evaluates the impact of an alternate energy medicine i.e. Mr. Trivedi’s biofield energy treatment on S. marcescens for changes in sensitivity pattern of antimicrobial, biochemical characteristics, and biotype number. S. marcescens cells were procured from MicroBioLogics Inc., USA in sealed pack bearing the American Type Culture Collection (ATCC 13880) number and divided into two groups, Group (Gr.) I: control and Gr. II: treated. Gr. II was further subdivided into two sub-groups, Gr. IIA and Gr. IIB. Gr. IIA was analyzed on day 10, while Gr. IIB was stored and analyzed on day 159 (Study I). After retreatment on day 159, the sample (Study II) was divided into three separate tubes as first, second and third tube, which were analyzed on day 5, 10 and 15 respectively. All experimental parameters were studied using the automated MicroScan Walk-Away® system. Antimicrobial susceptibility results showed that 42.85% of tested antimicrobials results in altered sensitivity pattern, while decreased minimum inhibitory concentration values in 40.62% tested antimicrobials as compared to the control after biofield treatment on S. marcescens. The biochemical study showed that 12 out of 33 tested biochemicals (36.36%) were reported for alteration of biochemical reactions pattern as compared to the control. Biotype study showed an alteration in biotype number in all the experimental treated groups as compared to the control. These results suggested that biofield energy treatment has a significant impact on S. marcescens. Overall, it is expected that Mr. Trivedi’s biofield energy treatment as an integrative medicine could be better therapy approach in near future.
