AbstractThe probiotic strains of Lactobacillus casei IMV B-7280, Bifidobacterium animalis VKL, B. animalis VKB (individually) or L. casei IMV B-7280 - B. animalis VKB - B. animalis VKL composition balanced the Th1/Th2 cytokines production at normal condition and in the cases of experimental intravaginal staphylococcosis in BALB/c mice in different periods of observation. L. casei IMV B-7280 and B. animalis VKB (individually) at normal condition increased the Th1 type cytokines interleukin (IL)-12 and interferon (IFN)-γ production. Instead, B. animalis VKL after injection into intact mice did not affect the IL-12 production but slightly increased the IFN-γ production. In the cases of experimental intravaginal staphylococcosis in mice the balancing of Th1/Th2 immune response under the influence of L. casei IMV B-7280 is due to increased production of IL-12 and IFN-γ, as well as decreased Th2 type cytokine IL-4 production. The IL-12 and IFN-γ production in staphylococcus-infected mice that received B. animalis VKL or B. animalis VKB (individually) was increased, but these probiotic bacteria had no significant effect on IL-4 production. Under the influence of L. casei IMV B-7280, B. animalis VKB, B. animalis VKL (individually) in the cases of experimental intravaginal staphylococcosis in mice the IL-4/IFN-γ ratio was significantly decreased. The shift from Th2 to Th1 type cytokines production was also observed in staphylococcus-infected mice that received L. casei IMV B-7280 - B. animalis VKB - B. animalis VKL composition. The IL-12 and IFN-γ production was increased, instead, IL-4 production as well as IL-4/IFN-γ ratio were decreased in mice that received this probiotic composition in different periods of observation.So, L. casei IMV B-7280, B. animalis VKB and B. animalis VKL (individually) and L. casei IMV B-7280 - B. animalis VKB - B. animalis VKL composition are promising to create highly effective immunobiotics with immunomodulatory effect that are able to balance Th1/Th2 type of immunity by shifting the cytokine profile with decreased the IL-4/IFN-γ ratio. Key words: lactic acid bacteria; bifidobacteria; mice; intravaginal staphylococcosis; cytokines.
