    摘要: The present invention encompasses a vaccine composition and method of use for treating heartworm infestation in mammals. The vaccine composition includes chimeric antigens engineered and manufactured using the genetic code (i.e., the amino acid or protein sequence) of the target sequence. After introduction of the vaccine composition containing the target antigen into the host (e.g., a canine), the host will generate antibodies as part of its robust immune response to the antigen. As the antibodies circulate through the host's plasma, heartworm larvae will consume the antibodies as they feed on the plasma. The antibodies will then act on internal targets of the worm recognized as antigens.

    摘要: The invention is a pour-on antiparasitic formulation having superior water resistant properties. The pour-on formulation utilizes one or more polymers (water insoluble with or without water soluble) in the range of about 5 to about 40% w/w, one or more solvents in the range of about 50 to about 94% w/w, with or without additive (e.g., isopropanol or ethanol) in the range of about 5 to about 30% w/w, and optionally a plasticizer in the range of about 0.5 to about 25% w/w. The pour-on antiparasitic formulation features limited spreading when applied to animals (cattle, sheep, dogs and the like). The pour-on antiparasitic formulation further partially evaporates, leaving a water resistant polymer matrix that diffuses at least one active ingredient to the animal's skin.
