The technology disclosed herein relates to, at least in part, a removable imaging cassette. An illumination plate is configured to transmit light. A cassette body defines an outer surface and a cassette cavity within the outer surface, where the outer surface surrounds the illumination plate. The cassette cavity abuts the illumination plate. A light source is disposed in the cassette cavity. Mating electrical contacts extend through the outer surface of the cassette body, where the mating electrical contacts are operably coupled to the light source.

The invention disclosed herein concerns screening and early detection of a variety of disease conditions in seemingly healthy subjects, enabling early intervention and treatment.

A method of analysis using mass spectrometry and/or ion mobility spectrometry is disclosed. The method comprises: using a first device to generate smoke, aerosol or vapour from a target comprising or consisting of a microbial population; mass analysing and/or ion mobility analysing said smoke, aerosol or vapour, or ions derived therefrom, in order to obtain spectrometric data; and analysing said spectrometric data in order to analyse said microbial population.

The present invention is directed to methods for the growth, enrichment and isolation of microbes within a sample for further use in presumptive identification of pathogenic bacteria that may therein be contained.

A method for monitoring microbial levels in a wellbore fluid is provided. The method includes collecting a wellbore fluid sample, recovering ATP from the wellbore fluid sample, using the recovered ATP in an ATP-mediated oxidation of luciferin to oxyluciferin to yield photons, quantifying the photons, correlating the quantified photons to an ATP concentration, comparing the ATP concentration to predetermined action levels, and taking countermeasures when the ATP concentration exceeds the predetermined action levels.

A method is disclosed comprising providing a biological sample on a swab, directing a spray of charged droplets onto a surface of the swab in order to generate a plurality of analyte ions, and analysing the analyte ions.

A non-pyrogenic preparation containing nanoparticles synthesized by magnetotactic bacteria for medical or cosmetic applications. The nanoparticles are constituted by a crystallized mineral central part including predominantly an iron oxide, as well as a surrounding coating without material from the magnetotactic bacteria.

One aspect of the present disclosure can include a method for reducing or alleviating inflammation in the digestive tract of a subject in need thereof that consumes a disruptive dietary component. One step of the method can include assaying a previously obtained fecal sample from the subject for the presence of one or more Proteobacteria and an activity level of a peroxidase enzyme. The subject can decrease ingestion of the disruptive dietary component if the assayed presence of the one or more Proteobacteria and the activity level of the peroxidase enzyme are increased as compared to control levels.

The present invention provides methods and systems to accurately detect and measure levels of endogenous antibodies, for examples endogenous IgA, to particular antigens in a biological sample from a companion animal, which is useful to diagnose inflammatory conditions, including bowel disease (IBD), gastrointestinal infections, and food sensitivities in companion animals, e.g., dogs or cats, and to distinguish among such gastrointestinal disorders. Such methods and systems identify whether a sample from the patient is associated with an inflammatory condition, infection, and/or food sensitivity condition, by using non-invasive means, thus conveniently providing information useful for guiding treatment decisions.
