radical reactions or the
repair process of DNA
in either prokaryotic or
eukaryotic cells [115].

30, 60, 80 and 100 mT
(Magnetic fi elds were
applied in aerobic and
anaerobic conditions).

• Magnetic fi elds may
induce active oxygen
formation.
• Radical reactions with
these paramagnetic ions
of oxygen are effected by
magnetic fields.
• Mechanism of effect of
magnetic fi eld may be
different in gram posi-
tive and gram negative
bacteria [119].

Streptococcus mutans,
Staphylococcus aureus and
Escherichia coli
(24 hours)

Findings suggested that −

• Oxygen related to

mutans, S. aureus.
• No growth effects were
detected on E. coli

Using the scanning near

could provide other

for these
