Summary: | Treatment of
infection by common drugs may be associated with several problems such as antimicrobial resistance to commonly used antibiotics and side effects of employed drugs. Therefore, exploration of non-chemical compounds which are safer than chemical ones is becoming important as an alternative therapy. The purpose of this study was to evaluate the effects of lactic acid bacteria (LAB) against clinical strains of
.
Study of antibacterial effects of LAB against
strains included: evaluation of LAB effects as well as its cell-free supernatant (CFS) to reduce the number of
, and to examine the effects of CFS to inhibit the urease activity of
. The anti-adhesion effect of LAB on adherence of
to epithelial cell line was also evaluated.
Evaluation of the anti
effect of LAB depended on the strain of
and Lactobacillus. However, CFS of LAB reduced significantly the growth of all
strains. Also, urease activity of
strains was inhibited by CFS of LAB demonstrating that their organic acid may have a role in this inhibition. The significant anti-adhesion effect of LAB on adherence of
was also observed.
Presence of LAB and/or their CFS can reduce the count of
, inhibit the urease activity of
, and reduce adhesion of
to epithelial cell line. This may be important for the impact of
colonization in the host stomach. |
