Abstract: It is an object of the present invention to provide a transmission-blocking vaccine using an immunogenic protein which is specifically expressed in the oocyst stage of malaria parasites or a peptide fragment thereof, and an oral transmission-blocking vaccine capable of immunizing various animals involved in the malaria infectious cycle with such a vaccine. The present invention relates to a malaria transmission-blocking vaccine for oral administration containing an immunogenic protein derived from malaria parasite which is specifically expressed in the oocyst stage of malaria parasites or a peptide fragment thereof, and a method of blocking the transmission of malaria using the same.

Abstract: The object of the present invention is to provide a therapeutic agent illustrating an immediate and sustained effect on chronic intractable external otitis. The present invention provide a composition, pharmaceutical composition, food and feed for preventing and/or treating chronic intractable external otitis, each comprising interferon-? (IFN?) as an active ingredient. Orally administering the composition of the present invention can provide inhibition, alleviation, treatment and prevention for chronic intractable external otitis. According to the present invention, IFN? can give a sufficient effect even when administered in a very small amount.

Abstract: The present invention provides oral compositions which contain interferon ? (IFN?) as an active ingredient for preventing and/or treating periodontal disease. The number of causative microorganisms of periodontal disease can be suppressed by administering the compositions into the oral cavity. IFN? of the present invention can produce a sufficient effect even when administered at a very low dose. Furthermore, the compositions of the present invention can also be readily administered to animals such as dogs by formulating them into feed or such.

Abstract: Immunity against protozoan is conferred on an animal by a method comprising orally administering to an animal a transformed plant cell comprising a polynucleotide encoding a protective antigen against protozoiasis development, a transformed plant or its progeny or clone comprising the transformed cell, a propagation material of the plant or its progeny or clone, a processed material or extract of the above cell, plant, or its progeny or clone, or propagation material, or a protective antigen against protozoiasis development isolated from the transformed plant cell or the transformed plant or its progeny or clone.

Abstract: When ELISA antibody titer dropped in chickens intramuscularly inoculated with an oil vaccine, recombinant HA and NP antigens prepared using gene recombinant technology were orally administered in combination with synthetic oligo CpG as a mucosal adjuvant to the chickens. Even when the immune response induced with the oil vaccine was impaired, the antibody titer was re-induced by orally administering the recombinant HA and NP antigens, and synthetic CpG-ODN in combination.

Abstract: Leaves of potato plants transformed with a vector that expresses an R7 immunogenic protein gene derived from second-generation schizonts of Leucocytozoon caulleryiwere administered to chickens as an oral vaccine. As a result, the present inventors succeeded in increasing the antibody titer of the chickens.
