Abstract: A method for detecting a parasitic worm infection of the digestive tract of a mammal. The method includes detecting the binding of a worm antibody to a worm antigen present in the soluble portion of a fecal sample of infected mammals.

Abstract: A method and device for determining a feline immunodeficiency virus infection or vaccination in an animal. The method includes contacting a biological sample from a felid with various FIV polypeptides and determining the binding of antibodies in the sample to the polypeptides. The determination of whether an animal is infected with FIV or has been vaccinated against FIV can be determined by measuring the animal's immune response to an FIV env polypeptide. A device for detecting FIV antibodies is provided.

Abstract: Tissue homogenizer devices for testing a sample of blood and/or tissue are provided. A device may include an outer cylinder; an inner cylinder slidably disposed within a lumen of the outer cylinder and defining a chamber therewithin; and a seal extending across an open distal end of the inner cylinder. The device may further include a piston extending proximally from a closed proximal end of the inner cylinder and through an open proximal end of the outer cylinder. Methods of using the devices disclosed herein are also provided.

Abstract: A method and device for determining a feline immunodeficiency virus infection or vaccination in an animal. The method is an assay involving contacting a biological sample from a felid with an env FIV polypeptide and determining the binding of antibodies in the sample to the polypeptide. The assay is optimized by adjusting the concentration of the sample and reagents, and the time and temperature of the incubation, so that antibodies in samples from vaccinated animals do not substantially bind to the polypeptide.

Abstract: In one aspect, a kit for the semi-quantitative measurement, in a liquid sample, by competitive immunoassay, of a first member of a specific binding pair, the kit including a solid support bearinga reference area which provides a detectable signal in the immunoassay, anda first and a second test area exposed to contact the sample, each test area containing a different amount of second or first member of the specific binding pair,whereby the intensity of the detectable signal from the reference area can be compared with the intensity of any detectable signals from the first and second test areas in the presence of an unknown quantity of the first member in the sample.
