Objectives: To investigate the effects of a probiotic mixture that
was isolated from human gut flora, and a standard probiotic strain
Lactobacillus GG (LGG) on allergic immune responses in an
animal model.
Materials and Methods: Three Enterococcus faecalis, 8
Lactobacillus plantarum, and 2 Lactobacillus rhamnosus strains
were included in the mixture. Balb-c mice in the study groups
were given the probiotic mixture, and standard strain LGG, and
animals in the control groups were given skimmed milk for 28
days. The mice in the study groups and the positive control group
were immunized with an intraperitoneal injection of ovalbumin
(OVA) on days 14 and 21. An enzyme-linked immunosorbent
assay was used to study the OVA-specific IgE levels in the mice
serums.
Results: The most remarkable results were that OVAspecific
IgE levels were significantly higher (P<0.001) in
the positive control group compared with the nonimmunized
negative control group, and OVA-specific IgE levels in the
study groups were significantly lower than the positive control
group (P<0.001).
Conclusion: The data of the present study suggest that
oral administration of probiotics prevents IgE-mediated OVAhypersensitivity;
however, the immunoregulatory effects of
strains must be described in detail while preparing probiotic
mixtures.
