Immunoprotection by beta-1,3 glucan antigen combination in Plasmodium berghei infection in mice.

ABSTRACT

In an attempt to protect mice against experimental infection with P. berghei, mice were immunized against soluble extract of P. berghei in combination with beta-1,3 glucan or FCA and also independently. Mice immunized against P. berghei antigen-glucan developed well defined cell mediated and humoral immune responses, while mice injected with antigen FCA or antigen alone developed only an antibody response. Antigen-glucan immunization afforded a high degree of immune protection to the host against the challenge with live parasites.
