Abstract: It is to provide intestinal symbiotic bacteria having an action of increasing an IgA content in milk. An agent containing one or more bacterial strains selected from: a bacterial strain of the genus Bacteroides which has a 16S rRNA gene having at least 90% identity to the nucleotide sequence represented by SEQ ID NO: 1, and has an action of increasing an IgA antibody content in milk; and a bacterial strain of the genus Prevotella which has a 16S rRNA gene having at least 90% identity to the nucleotide sequence represented by SEQ ID NO: 2, and has an action of increasing an IgA antibody content in milk is used as an agent for increasing an IgA antibody content in milk.

Abstract: Described herein is the development of fusion proteins useful for inducing tolerance in a subject. In particular embodiments, the tolerizing agents are useful for influence autoimmune, inflammatory, and/or allergic reactions. Example tolerizing fusion proteins contain a targeting portion (which delivers the fusion protein) and a toleragen or allergen or other antigen to which tolerance is desired in a subject. In particular examples, it is demonstrated that a p?1 fusion protein, when administered orally, facilitates systemic and mucosal tolerance. Also described is the nasal delivery of fusion proteins, for instance for restoring immunogenicity.
