Background: (LM) is a life-threatening bacterium affecting many individuals worldwide, including elderly people, pregnant women, and immune-deficient patients.
Aim: Whole-cell killed formalin of LM antigens (WKLMAgs) and culture filtrated proteins (LCFPs) against challenge-attenuated LM after two booster doses (0 and 14 days) of immunization act as an antigen activating a high level of IgG3, IgM, CXCL2, and IL-1 beta.
Methods: Forty male rats were randomly assigned to four groups.
