This phenomenon is called "bacterial antagonism
," "bacterial interference," or "colonization resistance" [9,10].
Key words: Acid tolerant bacteria; bacterial antagonism
; lactobacilli; probiotics.
(1,2) The inhibition of the growth of one bacterial species by the [H.sub.2][O.sub.2] generated by another species is a well-described mechanism of bacterial antagonism
. (3) In vitro studies have indicated that [H.sub.2][O.sub.2]-producing lactobacilli inhibit various organisms, including Gardnerella vaginalis, Neisseria gonorrhoeae, anaerobes, and human immunodeficiency virus (HIV).
Human breast milk, which contains bioactive components that encourage the growth of intestinal bifidobacteria in infants, may alter bacterial antagonism
for essential nutrients and impede overgrowth of undesirable aerobes.
Indeed, one of the studies of bacterial antagonism
in the nasopharynx concentrated on interactions between species rather than between serotypes of the same species (30).
Key words: Corrosion inhibition, Bacterial antagonism
and corrosion, Bacterially influenced corrosion.
