Abstract: The present invention provides a method for controlling ectoparasites of small rodents, thereby preventing the transmission of diseases by arthropod vectors. The invention further provides an enclosure having openings for entry of rodents, and having arranged therein one or more applicators which are configured to contact rodents entering the chamber and having an ectoparasiticide on the applicator for application to the rodents.

Abstract: An enclosure is provided having openings for entry of rodents within the enclosure. There is arranged one or more applicators in the form of a suspended flexible web configured to contact rodents entering the chamber and having a chemical on the web for application to the rodents.

Abstract: Methods for detecting parasites, such as Cryptosporidium parvum, in turbid and non-turbid samples by solubilizing molecular markers or antigens of the parasite. The molecular markers are solubilized by incubating a sample containing the parasite with a solubilization buffer and detecting the solubilized antigens by electrochemiluminescence. The solubilization buffer contains one or more detergents alone or in combination with one or more denaturing agents in a buffered solution. The methods are an improvement over existing immunofluorescence assays for C. parvum because the methods described herein are quantitative, reproducible, have high sensitivity, are not labor-intensive, require only minimal sample processing, and avoid being adversely affected by sample turbidity. In addition, by using a electrochemiluminescence assay, microscopy is not required.

Abstract: Genes isolated from Neisseria memingitidis, as well as isolated nucleic acids, probes, expression cassettes, polypeptides, antibodies, immunogenic compositions, antisense nucleic acids, amplification mixtures, and new invasion deficient swains of Neisseria meningitidis are provided Methods of detecting Neisseria meningitidis and Neisseria meningitidis nucleic acids, and methods of inhibiting the invasion of mammalian cells by Neisseria meningitidis are also provided.

Abstract: A fast, simple, and reliable method and apparatus for recording cough sounds for diagnosing pulmonary disorders and diseases is provided. This method uses signal analysis techniques to extract quantitative information from recorded cough sound pressure waves. The generated data can be used to diagnose pulmonary disorders and diseases as well as track the effectiveness of treatment regimes over time. The method can also be used to quickly and reliably screen individuals at risk of pulmonary disorders and diseases. A system according to one embodiment includes a mouthpiece connected to the proximal end of a tube. The distal end of the tube is connected to a flexible tube. A microphone is attached to the tube between the distal and proximal ends therof for recording sound pressure waves. A calculated cough sound index (CSI) can be used in diagnostic applications.

Abstract: A method is disclosed for monitoring local reactions, such as inflammatory responses, associated with injection sites. The method is performed using a temporary tattoo, which is transferred from a substrate to the skin of a subject, to measure the local reaction to an injection. A kit is also disclosed that can be used to perform the disclosed method. One example of the method includes transferring from the substrate to the subject's skin a temporary tattoo having a plurality of concentric rings and using the rings to measure the local reaction. For example, if the local reaction exceeds the boundary of the largest ring, the local reaction is considered clinically significant and additional medical interventions may be sought.

Abstract: The nucleic acid sequence encoding the internal transcribed spacer 2 region of Candida, the organism causing candidiasis, for various Candida species. Nucleic acid molecules useful as probes for detecting Candida species are described. The nucleic acid molecules are useful in methods for the detection and diagnosis of Candida infection in a sample or subject.

Abstract: The present invention provides a method of increasing the recombinant expression and solubility of influenza A virus M2 polypeptide comprising nucleic acids encoding variants of the M2 protein of influenza A virus in which transmembrane and other hydrophobic domains have been deleted. The present invention also provides purified polypeptides encoded by the nucleic acids, which polypeptides are immunogenic and are less hydrophobic than full-length M2. Also provided are vaccines comprising variants of M2 expressed in prokaryotic hosts. Further provided are methods of preventing influenza A infection using vaccines comprised of variants of M2. Also provided are antibodies raised against the variants of M2, and use of such antibodies in diagnosis and treatment of influenza A infections.

Abstract: A mosaic protein comprising a variety of immunoreactive antigenic epitopes from several genotypes of hepatitis C virus. The mosaic protein provides a sensitive and specific immunological hepatitis detection assay. A restriction enzyme assisted ligation method of making an artificial gene permits controlled construction of mosaic proteins, and allows confirmatory expression of the intermediate gene products.

Abstract: The present invention comprises spumavirus isolated from humans. More specifically, the spumavirus of the present invention was isolated from humans who had exposure to nonhuman primates. Importantly, the spumavirus of the present invention or antibodies to the spumavirus can be used to detect the presence of spumavirus or antibodies in body fluids, for pathogenicity studies of related viruses, and as a vector for gene therapies.

Abstract: The present invention provides an artificial organ system comprising an endothelial cell layer, an epithelial cell layer and an artificial microporous membrane, having pores therein, disposed between and in direct contact with the endothelial cell layer and the epithelial cell layer such that the membrane has an endothelial side and an epithelial side. The present invention also provides an artificial organ system contained in a vessel comprising an upper chamber into which the epithelial side faces and containing the epithelial cell layer, and a lower chamber into which the endothelial side faces and containing the endothelial cells. The present invention also provides an artificial lung system comprising an endothelial cell layer, an alveolar epithelial cell layer and an artificial microporous membrane, having pores therein, disposed between and in direct contact with the endothelial cell layer and the alveolar epithelial cell layer such that the membrane has an endothelial side and an epithelial side.
