ABSTRACT: This study was prepared due to a lack of studies on the immune modulatory effects of prodigiosin in mice against bacterial infection and the increased demand for natural resources. This study aimed to extract prodigiosin from Serratia rubidaea against Citrobacter freundii in mice by evaluating its immunomodulatory activity and histological alterations. A total of twenty-four Swiss mice were divided up into four groups of six mice each. C. freundii (1 × 106 cfu/ml) was administered orally to groups (2, 3 and 4) as an infectious dosage, and one milliliter was administered to the first group as a negative control. Following 24 hours from C. freundii infection, the Group 3 and Group 4 groups were given crude prodigiosin extract in the following dosage amounts: the third and fourth groups received (500 and 1000 µg/ml Intraperitoneal) respectively. ELISA test was performed to assess IgM, IL-6, and IL-10 on days 3, 7 and 14. IgM and IL-6 findings demonstrated a significant increase in Group2 and Group4 with differences (P
