This disclosure relates to a sensor that detects bacteria cells comprising (a) a primary negatively charged, nanoparticulate sensing material; (b) a secondary positively charged, fluorescent sensing material; (c) a housing; and (d) at least one illuminator. This disclosure further relates to a method for detecting bacteria cells.

The invention relates to an ex vivo method for detecting or monitoring the progression of a chronic degenerative disease, in a sample of human or animal biological fluid, by immunoassay for the presence of antibodies in the sample, including at least: one or more antibodies directed against at least one endobacterium, and one or more antibodies directed against a tryptophan oxidation product.

The invention also relates to a kit for implementing such a method.

An object of a device and a method for detecting a substance to be measured according to an embodiment of the present disclosure is to conveniently detect a biological substance, such as a bacterium or a fungus. The detection device according to an embodiment of the present disclosure includes a container that retains a solution containing a substance to be measured and a magnetic labeling substance that binds specifically to the substance to be measured, a flow generating unit that generates a flow in a first direction at least in the solution, a magnetic field generating unit that generates a magnetic field gradient in the solution, and a detection unit that detects composite particles, based on motion of particles in a predetermined region in the solution, the composite particles including the substance to be measured and the magnetic labeling substance bound together.

The presently disclosed subject matter provides compositions, kits, and methods comprising imaging agents that can detect Programmed Cell Death Ligand 1 (PD-L1). The presently disclosed imaging agents can be used to detect diseases and disorders, such as cancer, infection, and inflammation, in a subject.

The invention provides compositions and methods for preventing, treating and diagnosing infection by Salmonella enterica serovar typhi (S. typhi) and/or S. paratyphi, i.e., typhoid fever.

Compositions for the treatment of colorectal cancer target bacterial biofilms in the gastrointestinal tract. Methods of treatment include one or more agents which target bacteria and the bacterial biofilms.

An improved system, method and interface for automated rapid antimicrobial susceptibility testing (AST) is disclosed which includes, in one aspect, a carrier population station comprising a workstation having a graphic user interface (GUI). The GUI accepts information from a lab technologist, including information related to a scope of testing to be performed on a microorganism containing sample. The GUI controls intelligent assignment of microorganism containing samples to test panels in a manner that maximize utilization of the test carrier by grouping together samples of similar tests scopes and advantageously testing those samples using one multiplexed test panel. Customizing workflow in accordance with test scope to facilitate parallel processing of multiple samples advantageously reduces laboratory waste, decreases test latencies, increases AST system throughput and efficiency, and thus lowers the costs to the AST lab.

The present disclosure relates to a novel method for lateral flow immunoassay (LFIA) by utilizing plasmonic enhancement strategy. More specifically, the present disclosure provides a plasmonic enhanced lateral flow sensor (pLFS) concept by introducing a liposome-based amplification of the colorimetric signals on the lateral flow platform for ultrasensitive detection of pathogens.

The invention provides anti-ETEC adhesin protein antibodies and methods of using the same.

Systems comprising a diffraction grating, a light source configured to illuminate at a limited waveband, an optical detection system configured to detect zero and non-zero diffraction orders of light, and a signal processing unit adapted to analyze zero and non-zero diffraction orders to determine time-dependent changes in effective optical depth are provided. Methods for use of these systems for real-time detection of cell replication, microorganism detection, and for selecting a therapeutic agent for treating a microorganism are also provided.
