|a Systemic and mucosal and immune responses can be manipulated with immunomodulators. Here we show the modulatory effects of cholera toxin (CT) and beta-1,3-glucan (GLU) on the rat antiamebic serum and fecal antibody responses to one or four intraperitoneal (IP) or intragastric (IG) doses of glutaraldehyde-fixed Entamoeba histolytica trophozoites (GFT). One IP dose of GFT maximized serum IgM and IgG antiamebic antibodies on days 4 and 9, respectively; CT coadministration increased IgM antibodies, whereas IgG titers increased with CT or GLU; coproantibodies were undetectable after GFT alone or coadministered with GLU, whereas CT coadministration maximized fecal IgA antibodies on day 6. One IG dose of GFT alone increased serum IgM and IgG antibodies 2.5 times and no further increases were detected using GLU, whereas CT doubled serum IgG antibodies; GFT did not affect the coproantibody responses, whereas GLU coadministration maximized IgG coproantibody levels on day 6 and CT increased IgG and IgA coproantibody levels on the same day. On the other hand, four IG doses of GFT alone or with GLU induced tolerance, whereas GFT alone via the IP route increased serum antibodies slightly and GLU coadministration increased serum IgG antibody titers 300-fold. CT coadministration by both routes increased IgA coproantibodies, and simultaneous CT+GLU coadministration induced lower responses than either CT or GLU. Different antiamebic immune responses might therefore be attained through the use of different immunization routes and immunomodulators to induce protective immunity against intestinal or extraintestinal amebiasis
