This invention relates to a method and device for improving the accuracy and performance of detecting or diagnosing sexually transmitted infections (STIs) or STI-causing pathogens. In one embodiment, the present method and device are related to removing one or more interfering molecules such as urea from urine sample, where these interfering molecules alter the performance of Lateral-Flow Immunoassay (LFA). In one embodiment, an aqueous two-phase system (ATPS) embedded entirely within a porous material allows spontaneous phase separation and the target STI-causing pathogens is concentrated in one of the separated phases. In one embodiment, a detection module such as the Lateral-Flow Immunoassay (LFA) is used in connection with other modules so as to detect or diagnose the sexually transmitted infections or the pathogens associated with STIs with an improved performance.

Provided herein are multiplex assays for detecting antibodies indicative of presence and stage of syphilis infection in an individual. Individuals infected with syphilis produce antibodies directed to syphilis components and the lipid cellular debris associated with the infection. The present disclosure represents the first combination of these diverse antibody targets in a single assay.

This invention relates, inter alia, to an immunogenic fragment of a Neisserial Heparin Binding Antigen (NHBA) protein of Neisseria gonorrhoeae (SEQ ID NO: 1) for the prevention and treatment of Neisseria gonorrhoeae or gonococcal- or meningococcal-associated diseases and conditions. In some embodiments, the immunogenic fragment corresponds to a C-terminal fragment of the protein (SEQ ID NO: 2).

A method is presented for treating herpes simplex virus (HSV) infection comprising: (a) locally administering a substance that induces a delayed type hypersensitivity (DTH) response to a patient at a site of an HSV lesion to induce a DTH response at the site of the lesion during one or more outbreaks of the HSV infection.

Detectors and related methods and systems are described, based on a primary binding compound and a secondary binding compound used in combination with a support to detect a target in a sample.

Diagnostic systems, methods, and devices employing low-cost handheld components are disclosed herein. A diagnostic system can include a diagnostic device that is configured to perform one or more assays on a fluid sample, such as a whole blood sample, in one or more microfluidic channels or chambers. The diagnostic device can move the fluid sample into or through the one or more microfluidic channels or chambers without using any electrical power, for example, using manual actuation to generate a positive or negative pressure within the diagnostic device. The diagnostic device can have a connector for interfacing with a separate handheld unit that can provide power and data processing. For example, the separate handheld unit can be a smartphone or PDA, and the connector can interface with an existing input/output port of the unit to draw power and/or transmit data.
