Simple one-step identification and confirmation of a range of pathogenic bacteria.
A rapid test for the identification and confirmation of Listeria spp. From colonies grown on selective media.Once isolated on agar plates, colonies resembling Listeria spp. are tested to confirm that they belong to that genus. Other organisms may be isolated from food samples which may resemble Listeria spp.To confirm the presence of Listeria spp. a number of tests are normally used including aesculin hydrolysis, oxidase, catalase, motility (differential at 25°C and 37°C).Microgen Listeria latex was developed as an alternative to this battery of tests. Although individually these tests are inexpensive, they are time consuming to perform. The use of a simple latex agglutination test provides a real-time 2 minute test for the confirmation to genus level of Listeria spp.
