An article for detectingmicroorganisms is provided. The article comprises a highly selective nutrient medium and a plurality of indicator systems. A method of using the article to detectmicroorganisms is also provided.

detection articles and methods of use

A method of detecting amicroorganism 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 amicroorganism, and a second indicator system that is converted to a second detectable product by &#x3b2;-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.

Method of detecting amicroorganism

A composition is provided for detecting amicroorganism 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 amicroorganism, 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 &#x3b2;-galactosidase enzyme activity to a third detectable product. Methods of using the composition to detect amicroorganism are also provided.

Method of detecting a salmonella microorganism

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.
