Immunomodulatory effects of Pediococcus acidilactici on BALB/C mice Immunosuppressed by Cyclophosphamide

Background: The live microorganisms that present in food in addition dietary supplements called Probiotics they have beneficial effect in the human intestine. In the last years, Probiotics has become within treatment options for several disease included immune system. The advent and use of probiotics seem to be increasing day by day all over the world. Objective: The current study included detection of efficacy Pediococcus acidilactici as immunomodulatory in mice that treated with cyclophosphamide. Design: To detect efficacy of Pediococcus acidilactici as immunosuppressive model was used. This model was completed by taking 20 male BALB/C mice with six-weeks old to divide into (5) groups :(G 1) group is the normal control. (G2) group: the group that injected with cyclophosphamide. (G3) group: the immunosuppression plus Pediococcus acidilactici (6×108 CFU/ml). (G4) group: the immunosuppression plus Pediococcus acidilactici (6×104 CFU/ml). last (G5) group : is the group that treated with probiotics. Results: In the current study, thymus and spleen indicators were significantly higher in treated groups than those of (G1) group (NC) with (0.323±0.34) (P<0.05), also Macrophages phagocytosis showed a clear increase in the three treated groups (76.625±108, 72.125±1.65, 87.750±1.32) respectively with significantly (P<0.05), as a compared with (G1) group (NC). Conclusions: The current study reveals the ability of Pediococcus acidilactici (6×109) CFU/ml to accelerate the healing of cyclophosphamide immunosuppressive mice. So, the activity role of probiotic strain as immunomodulator in this study leads us to urge the use it as an alternative treatment for chemical drugs that used against immunosuppression.
