Abstract

It was determined whether microencapsulation of rotavirus enhanced virus-specific immunity in mice. Combinations of several water-soluble anionic polymers and amines were tested for their capacity to form microcapsules which were stable in the presence of simulated gastric acid. Using the combinations of sodium alginate and spermine hydrochloride or sodium chondroitin sulfate and spermine hydrochloride we found that microcapsules (1) captured infectious rotavirus, (2) penetrated into the persisted in gut-associated lymphoid tissue (GALT) after oral inoculation, (3) delivered rotavirus antigen to GALT at levels greater than those detected after oral inoculation with free virus, and (4) enhanced the virus-specific humoral immune response after oral or parenteral immunization.
