Compact Dry™ LS (Listeria ssp)
Compact Dry™ offers a simple and safe procedure to detect and quantify microorganisms in foods, beverages, raw materials, cosmetics, pharmaceuticals, and environmental samples.
Listeria spp. are Gram-positive, motile (under mesophilic conditions) bacteria of clinical importance due to their virulence activity. Listeria spp. are found in many environments, such as soil, water, decaying vegetation, and animals.
LS Listeria ssp. Box of 100
In compliance with regulatory requirements, a USDA permit (VS 16-3) is mandatory for shipments from Canada to the USA due to the inclusion of peptone as an animal byproduct.
Enumeration of colonies can be performed from the front or the back of the Compact Dry plate.
Read against a white background with an adequate light source. The grid lines on the back of the plate are useful when high plate counts are present.
Colony morphology is best observed on the front of the plate. Colonies can be sampled for further isolated colony. Use an inoculating loop to transfer to an agar plate or a pipette tip to place into a growth medium. Gently remove a colony taking care not to disturb the surrounding growth medium.
