  • Publication number: 20230227923
    Abstract: Methods for determining bacterial identity and susceptibility or resistance to antibiotic or antimicrobial agents are provided. In one embodiment, the bacteria is cultured in the presence or absence or the antibiotic agent to generate a plurality of primary cultures, which are then cultured in the presence or absence of transforming phages to generate a first secondary culture that comprise transformed bacteria that have been treated with the antibiotic agent and a second secondary culture that comprises transformed bacteria that have not been treated with the antibiotic agent. The recombinant phages are specific to the bacteria and comprise a heterologous marker. The susceptibility or resistance of the bacteria to the antibiotic or antimicrobial agent is determined by comparing a level or activity of the marker in the first and second secondary cultures.

  • Patent number: 6663833
    Abstract: An assay device for the detection of analyte in a sample, methods and immunoassay formats for performing an assay with or without the device, and methods for manufacturing the device are provided. The device is a continuous liquid flow channel having a proximal and a distal end, with a detection membrane in fluid communication with the distal end of the flow channel. Interspersed between the assay buffer and detection membrane, and continuous with the liquid flow channel, are a sample delivery means, one or more reservoirs containing the reagents necessary for conducting the assay, and, optionally, mixing or incubation reservoirs for combining the sample and reagents. The geometry of the liquid flow channel regulates the flow rate of the liquids through the channel, thereby controlling incubation, mixing and reaction time. The preferred detection membrane is an immunochromatographic test strip containing immobilized reagents.
