A diagnostically useful carrier includes (a) a peptide including the amino acid sequence set forth in SEQ ID NO:1 or a variant thereof, and (b) a somatic lysate of Toxocara canis larvae. Further, a kit, use, methods, and compositions that include the diagnostically useful carrier are disclosed.

The present invention provides compositions and methods that can be used to determine a peptide signature for an antibody repertoire in a sample comprising multiple antibodies. The method can be used to characterize a phenotype in a sample, such as providing a diagnosis, prognosis or theranosis of a medical condition.

Trichinella can be detected in a tissue extract sample. A suitable kit includes (a) a detection carrier containing a first antibody against one or more antigens of Trichinella, and (b) (i) a second antibody against one or more antigens of Trichinella, wherein the second antibody is bound to a signal molecule, or (b) (ii) contains one or more antigens of Trichinella bound to a signal molecule, wherein the antigens of (b) (ii) are configured so as to dissolve binding of the antigens of (a) to the first antibody by competitive displacement.

Methods, devices, kits and compositions for detecting the presence or absence of hookworm in a fecal sample are disclosed herein. The methods, devices, kits and compositions of the present invention may be used to confirm the presence or absence of hookworm in a fecal sample from a mammal that may also be infected with one or more of roundworm, whipworm, and heartworm. Confirmation of the presence or absence of hookworm in the mammal may be made, for example, for the purpose of selecting an optimal course of treating the mammal and/or for the purpose of determining whether the mammal has been rid of the infection after treatment has been initiated.

Trichinella can be detected in a tissue extract sample. A suitable kit includes (a) a detection carrier containing a first antibody against one or more antigens of Trichinella, and (b) (i) a second antibody against one or more antigens of Trichinella, wherein the second antibody is bound to a signal molecule, or (b) (ii) contains one or more antigens of Trichinella bound to a signal molecule, wherein the antigens of (b) (ii) are configured so as to dissolve binding of the antigens of (a) to the first antibody by competitive displacement.

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.

Trichinella can be detected in a tissue extract sample.
