Abstract: The present invention relates to compositions and methods involving diagnostic tests with multiple test antigens. The present invention involves the expanded use of test antigens as cross-reactive control antigens (CCAs). The invention advantageously provides for enhanced test results analysis by simultaneously providing both test antigen and CCA signal results. These results, in turn, allow useful sample comparison and cross-reference between samples to more accurately identify and verify the fidelity of test results obtained for multiple infective agents at once. The present invention may include compositions and methods for detecting infection by Zika virus or another flavivirus, and may distinguish between infections caused by genetically similar agents.

Abstract: The present disclosure provides compositions and methods for detecting the presence of neutralizing antibodies in a sample. Unlike conventional assays, the methods provided herein do not require the use of live virus or virus pseudoparticles to identify neutralizing antibodies.

Abstract: The present invention provides rapid diagnostic assays for the detection of Leishmania which can readily be used in the field, leading to more rapid treatment. In certain embodiments, the inventive assays, including ELISA and lateral flow assays, employ antibodies that may be effectively employed to detect the Leishmania major antigen TSA, which is present in both promastigotes grown in culture and in amastigotes. Such assays may be employed to detect the presence of cutaneous leishmaniasis in a subject using scrapings, biopsies, and/or aspirates taken from cutaneous lesions.
