Microgen® Listeria latex test

A rapid test for the identification andconfirmation of Listeria spp. from
colonies grown on selective media. Listeria spp. are commonly found in soil and are transferred onto vegetable matter. Foods either derived from vegetables or which are derived from grazing animals and which are exposed to minimal processing i.e. dairy products, are the most common vector for the transmission of Listeria spp. to humans. There are 6 species commonly isolated, including Listeria monocytogenes which has been associated with human disease. L. monocytogenes is an opportunistic pathogen in that it will only cause disease in people with certain predisposing factors such as the immunosuppressed and pregnant women.
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.

Microgen® Listeria can be used to obtain rapid, presumptive-positive results from selective media thus giving an early indication of a failure in the production process. Where standard methods require it, Microgen® Listeria can be used to screen colonies before full biochemical identification and can replace traditional agglutinating antibody methods.
