  • Patent number: 11512279
    Abstract: A system for generating and using an assay key comprising growth conditions for a set of microorganisms for a set of diverse QAC-based culture media under a variety of incubation conditions known to modulate the effect of QAC on growth of some microorganisms in the set. Each culture medium is characterized by a pH and includes one or more QACs and one or more growth supplements. The set of culture media includes media comprising various combinations of pH, QAC type, QAC concentration, growth supplement type, and growth supplement concentration. The assay key can be used to identify a microorganism by inoculating a variety of growth media within the key and incubating the inoculated media under conditions within the key and comparing the resulting pattern of microorganism growth across the media and conditions with growth patterns for various known microorganisms across the media and conditions that are within the key.

  • Patent number: 10870829
    Abstract: A system for identifying Candida auris is disclosed. The system has two aspects. The first is a positive selection of C. auris based on C. auris's distinctive resistance to quaternary ammonium compounds (especially at elevated incubation temperatures). The second is a negative selection of C. auris based on C. auris's distinctive sensitive to tert-Butyl-hydroperoxide. C. auris can be identified in a sample through use of a positive-selection culture medium, which fosters C. auris colony growth while suppressing growth of other yeasts. The isolate can be confirmed as C. auris through use of a negative-selection culture medium, which suppresses C. auris colony growth while permitting growth of other yeasts.
