The present invention relates to a strain of Neospora caninum for use in treating cancer or infectious diseases.

A method of immunizing a human against infection by parasitic worms, comprising orally administering a live attenuated recombinant bacterium, expressing at least one antigen corresponding to a parasitic worm antigen; and a sterile injectable vaccine comprising the at least one antigen corresponding to a parasitic worm antigen. The method is effective against worms, including schistosomes.

Provided herein are imidazopyrimidine compounds for use in enhancing human immune response and/or as adjuvants in vaccines.

The invention is based upon the identification of a number of antigens derived from a species of the genus Streptococcus, which are cross reactive and which may serve as the basis of useful compositions and tests and procedures capable of identifying and/or detecting Streptococcus sp in samples.

The present invention relates to a strain of Neospora caninum for use in treating cancer or infectious diseases.

A novel method of using an aquaporin protein from Rhipicephalus microplus (RmAQP2), fragments of RmAQP2, and/or the cDNA encoding RmAQP2 and/or the fragments are described. Immunogenic composition containing recombinant RmAQP2 and/or fragments of RmAQP2 are produced and administered to an ungulate which generates an immune response to RmAQP2. After feeding female ticks on the ungulate injected with RmAQP2 and/or fragments of RmAQP2, the female ticks have lower reproductive viability because of a reduced egg mass, reduced hatching percentage, and reduced survival of larvae. Thus, administering RmAQP2 and/or RmAQP2 fragments to an ungulate can reduce the incidence of R. microplus and also reduce the incidence of tick-borne pathogens in ungulates because of the lower number of R. microplus.

In various aspects and embodiments the invention provides methods and compositions for generating tick immunity.

The present invention is a multivalent immunogenic composition for immunizing an animal against filariasis. In some embodiments, the antigens of the multivalent immunogenic composition are protein-based, DNA-based, or a combination thereof. This invention also provides a method and kit for detecting a filarial nematode and determining vaccine efficacy.

The present invention provides methods, compositions, systems, and kits comprising nano-satellite complexes and/or serum albumin carrier complexes, which are used for modulating antigen-specific immune response (e.g., enhancing anti-tumor immunity). In certain embodiments, the nano-satellite complexes comprise: a) a core nanoparticle complex comprising a biocompatible coating surrounding a nanoparticle core; b) at least one satellite particle attached to, or absorbed to, the biocompatible coating; and c) an antigenic component conjugated to, or absorbed to, the at least one satellite particle component. In certain embodiments, the complexes further comprise: d) an type I interferon agonist agent. In some embodiments, the serum albumin complexes comprise: a) at least part of a serum albumin protein, b) an antigenic component conjugated to the carrier protein, and c) a type I interferon agonist agent.

The present invention relates to peptide fragments which have one or more shared and/or similar amino acid sequences to amino acid sequences of specific portions of the 14 kDa protein of S. mansoni (SM14) or related FABPs (Fatty Acid Binding Proteins), the peptide fragments functioning as continuous or discontinuous epitopic regions of the molecule or mimicking its biological activity. More particularly, the present invention relates to a method for constructing active peptide fragments, peptide fragments, immunogenic compositions and diagnostic kits using peptide fragments.
