Listeriosis is a serious infection caused by eating food contaminated with the bacteria Listeria monocytogenes. Persons with listeriosis usually have a fever, muscle aches, and sometimes nausea or diarrhea. L. monocytogenes is found in soil and water. Vegetables can become contaminated from the soil or from manure used as fertilizer. Animals can carry the bacteria and can contaminate foods of animal origin, such as meats and dairy products. Listeria has been found in raw foods, such as meat and vegetables, and in processed foods that become contaminated after processing.
Since Listeria is a bacteria of great hygienic and sanitary importance CONDA launches a new chromogenic medium for its rapid laboratory detection: Listeria Chromogenic Agar Base (Cat. Nº 1345).
This new chromogenic medium allows the identification and differentiation of Listeria monocytogenes from Listeria spp. What makes this product different from the traditional ones is that it is possible to differentiate the types of Listeria on one same plate, since, unlike the rest, Listeria monocytogenes presents an opaque white halo around the colony in 24 hours.
Listeria Chromogenic Agar Base has expanded our wide range of Chromogenic Media amongst which you can find Cat. Nº 1122, 1151 and 1340.
