Publication number: 20250092470Abstract: Provided herein are methods for detecting and discriminating bacteria and fungal species by nucleic acid amplification, then hybridization analysis on a microarray. Primer pairs are used to simultaneously amplify multiple ribosomal Hypervariable regions from the rDNA or rRNA in bacteria and/or fungi as a multiplex amplification reaction, wherein the resulting hypervariable region amplicon mix is analyzed by hybridization to nucleic acid probes that are complementary to unique sequence determinants within those amplified hypervariable regions. The combination of multiplex amplification and microarray hybridization is used for detection and differentiation of specific species within a microbial set relevant to human or animal health or environmental or agricultural analysis, based on simultaneous analysis of the sequence in two or more hypervariable regions, concurrently.Type: ApplicationFiled: September 20, 2024Publication date: March 20, 2025Applicant: PathogenDx, Inc.Inventors: Michael E.

Publication number: 20210317540Abstract: Provided herein is a method of quantitating a fungus in a plant, plant product or agricultural product. Total nucleic acids are isolated from a sample of the plant or plant product, and an asymmetric PCR amplification reaction is performed using fluorescent labeled primer pairs to obtain fluorescent labeled fungal amplicons. These amplicons are hybridized to fungus specific nucleic acid probes that are attached on a microarray support. The microarray is imaged to detect fluorescent signals from the fluorescent labeled fungal amplicons. The fluorescent signal intensity is correlated to the quantity of fungus.Type: ApplicationFiled: June 23, 2021Publication date: October 14, 2021Applicant: PathogenDx, Inc.Inventors: Melissa May, Frederick H.

Publication number: 20200191782Abstract: Systems and methods for low-cost point-of-care immunoassay are provided. The system comprises an emitter, two optical interference filters, a microscope slide, a photodiode detector, a circuit, and a measuring unit. The detector is placed upon the second filter, the slide, the first filter, and then the emitter. The emitter comprises non-organic light emitting diodes (LEDs) or organic light emitting diodes (OLEDs) that emits light of a first color. The slide is spotted with biofluid from a patient. Biomarkers in the biofluid is bound with immobilized fluorophores that emit light of a second color when stimulated by the light of the first color. The first and second filters band-pass the light of the first and second colors, respectively. The detector detects light of the second color. The current outputted from the detector is converted into a relatively-large output voltage by a circuit. A measuring unit measures the ramp time of the output voltage.Type: ApplicationFiled: February 7, 2020Publication date: June 18, 2020Inventors: Benjamin Katchman, Karen Anderson, Joseph Smith, Jennifer Blain Christen

Publication number: 20200080987Abstract: The present disclosure provides a method of using a wearable biofluid sensing device to develop a cytokine profile for an individual. The method includes taking concentration, ratio, and trend measurements of one or more cytokines in the individual's sweat, along with other contemporaneous device measurements to inform sweat rate, skin temperature, sweat sample pH, or other factors. The method further considers these measured values in the context of external information about the individual, and uses such information to develop (1) a baseline cytokine profile characterizing the individual's healthy cytokine levels, or (2) an inflammation profile for a physiological condition, which characterizes the expected cytokine levels for a physiological condition. Also included is a method to use a biofluid sensing device to determine whether an individual has a physiological condition by comparing device measurements to the baseline profile and inflammation profile. Results are then communicated to a device user.Type: ApplicationFiled: October 25, 2017Publication date: March 12, 2020Applicant: Eccrine Systems, Inc.Inventors: Kathy Cunningham, Gavi Begtrup, Benjamin Katchman

Publication number: 20190183394Abstract: The disclosed invention includes methods to employ wearable biosensing devices to accomplish the following: 1) screen for the presence of a disease or infection, including pre-symptomatic detection, and determination of the type (e.g., viral, bacterial, or fungal) of disease or infection present; 2) confirm the antigen and monitor the progress of an active infection; and 3) monitor the efficacy of a treatment program for a disease or infection. Such methods rely on the detection, in sweat or other biofluids, of proteins, nucleotides, DNA polymerases, proteases, group-specific antigens, antibodies, cytokines, or other molecules, that are produced by the body as part of the innate or adaptive immune responses to an infectious agent, or the infectious agent itself, its products, or derivatives. Some embodiments comprise a method of using such a biosensing device as a biosentinel against biological threats.Type: ApplicationFiled: August 2, 2017Publication date: June 20, 2019Applicant: Eccrine Systems, Inc.Inventors: Robert Beech, Evyn White, Benjamin Katchman
