Static magnetic field increases the sensitivity of Salmonella to gentamicin

Abstract

The present study was carried out to evaluate the effects of static magnetic field (SMF) on antibiotic sensitivity of Salmonella enterica subsp. enterica serovar Hadar. We have evaluated antibiotic susceptibility using the disc diffusion method following exposure to SMF. Our results showed that exposure to a 200-mT SMF static magnetic field increased the efficiency (p<0.01) of gentamicin against Salmonella Hadar but did not affect the diameter of the inhibition zone of some other antibiotics actives on Enterobacteria: penicillin, oxacillin, cephalotin, neomycin, amikacin, tetracyclin, erythromycin, spiramycin, chloramphenicol, nalidixic acid and vancomycin. © Springer-Verlag and the University of Milan 2010.
