Immunogenicity of Brucella Trivalent Immunogen-Containing Polyethyleneimine Nanostructure Targeted with LPS in a Mouse Model.

Brucella is a facultative intracellular gram-negative coccobacillus. It is nonsporulating and reproduced in macrophage phagosomes. The use of nanostructures as drug and vaccine carriers has recently received attention due to their ability to control the release profile and protect the drug molecules.
