  • Patent number: 10519481
    Abstract: A method of detecting a Salmonella microorganism is provided. The method includes the use of a selective growth medium, a first indicator system that is converted to a first detectable product by a Salmonella microorganism, and a second indicator system that is converted to a second detectable product by ?-galactosidase enzyme activity. The method further comprises inoculating the growth medium and incubating the inoculated growth medium at a temperature higher than 40 degrees C.

  • Publication number: 20190194595
    Abstract: A self-contained anaerobic environment-generating culture device is provided. The culture device includes a first substrate having opposing inner and outer surfaces, a second substrate having opposing inner and outer surfaces, a growth region disposed between the inner surfaces of the first and second substrates, an effective amount of a substantially dry enzyme component of an enzyme-mediated oxygen depletion system, an effective amount of a substantially dry enzyme substrate component of the enzyme-mediated oxygen depletion system, and a dry, cold-water-soluble gelling agent disposed in the growth region. The enzyme and enzyme substrate components are disposed in coatings in the growth region. The first and second substrates are substantially nontransmissible to gaseous oxygen. Methods of making and using the culture device area also provided.

  • Patent number: 9920350
    Abstract: A composition is provided for detecting a Salmonella microorganism in sample. The composition comprises at least one first selective agent that inhibits the growth of Gram-positive microorganisms, a first differential indicator system comprising at least one first differential indicator compound that is converted to a first detectable product by a Salmonella microorganism, and a second differential indicator system comprising a second differential indicator compound that is converted by urease enzyme activity to a second detectable product. Optionally, the composition may comprise a third differential indicator system comprising a third differential indicator compound that is converted by a ?-galactosidase enzyme activity to a third detectable product. Methods of using the composition to detect a Salmonella microorganism are also provided.

  • Patent number: 9873904
    Abstract: The disclosure provides culture devices and methods useful for detecting acid-producing bacteria in a sample. The devices include a nutrient medium and a pH indicator to detect and differentiate acid-producing microorganisms, such as lactic acid bacteria. Methods of use include detecting or enumerating acid-producing microorganisms. The methods further provide for the detection of gas-producing acid-producing bacteria.
