Abstract

We aimed to determine the impact of 50 Hz, 3 mT electromagnetic field (EMF) on the growth of Helicobacter pylori and the changes in morphology, survival and viability after exposure in both 20 and 120 min of in vitro experiments. The bacterial suspension (~108CFU/mL) of cultured H. pylori NCTC 11637 in Brucella Broth were exposed to 50 Hz EMF for 20 and 120 min in a microaerophilic condition at 25-28°C. Viability or culturability of 104 and 105 dilutions was determined after 20 and 120 min by spread plate colony count method. The exposure to 50 Hz EMF for 120 min had inhibitory effect on H. pyloricolonies with reduction in bacterial viability as well as morphologic changes which were observed from typical spiral form to elongated bacillary form.

 

Key words: Helicobacter pylori, electromagnetic fields.
