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 β-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.

Abstract: The present disclosure provides a culture device for enumerating colonies of microorganisms. The device can comprise a base, a coversheet, and a nonporous spacer member disposed therebetween. The spacer member comprises an aperture that defines a growth compartment. Disposed in the growth compartment are a cold water-soluble gelling agent, a dry oxygen-scavenging reagent, a dry buffer system, and an effective amount of a dry carbon dioxide-generating reagent. The buffer system is selected such that, when the growth compartment is hydrated with a predetermined volume of deionized water, an aqueous mixture with a pH less than or equal to 6.35 is formed.

Abstract: The present disclosure provides a culture device for enumerating colonies of sulfate-reducing microorganisms. The device includes a body having a waterproof base, a waterproof coversheet attached to the base, and a growth compartment disposed therebetween. The growth compartment has a perimeter and an opening. A portion of the perimeter is defined by a waterproof seal. The portion can include >50% of the perimeter. Disposed in the growth compartment are a dry cold water-soluble gelling agent, a dry culture medium selected to facilitate growth of a sulfate-reducing bacterium or indicator reagent for detecting hydrogen sulfide production by a sulfate-reducing bacterium, and a dry first oxygen-scavenging reagent.

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 β-galactosidase enzyme activity to a third detectable product. Methods of using the composition to detect a Salmonella microorganism are also provided.
