Publication number: 20250002969Abstract: A method of determining antibiotic resistance of bacteria includes dividing a sample including the bacteria into a plurality of sub-samples, mixing labeling: agents with each of the plurality of sub-samples. Each of the labeling agents is detectible via a detection system including a sensor to detect photoacoustic waves. The labeling: agents are further active to selectively bind with the bacteria. The method further includes applying an antibiotic to one or more of the plurality of sub-samples and not to one or more others of the plurality of sub-samples, characterizing at least one of the sub-samples to which the antibiotic has been applied and at least one of the sub-samples to which no antibiotic has been applied after a determined period of time via the detection system, and determining antibiotic resistance of the bacteria on the basis of the characterization via the detection system.Type: ApplicationFiled: August 20, 2022Publication date: January 2, 2025Inventors: John Alston Kellum, JR., Robert Hugh Edgar, Cierra Lynn White, John Andrew Viator, John D. Hempel

Patent number: 9151709Abstract: A multiple flow system and method for detecting substances in a fluid is provided. More specifically, a first fluid tube containing a first fluid and a second fluid tube containing a second fluid are coupled to a common fluid tube via a connector, such that alternating discrete compartments of the first fluid and the second fluid flow through the common fluid tube. The first and second fluids are immiscible. A substance detector, having a flow chamber with an internal wall, is coupled to the common fluid tube. The alternating discrete compartments of the first and second fluids flow through the flow chamber and are analyzed by the substance detector.Type: GrantFiled: September 8, 2011Date of Patent: October 6, 2015Assignee: The Curators of the University of MissouriInventors: Christine Mary O'Brien, Sagar K.
