General description

CLED (cysteine-, lactose- and electrolyte-deficient) Agar is recommended for isolation, enumeration and identification of urinary pathogens.
CLED Agar is commonly used in bacteriological analysis.

Application

CLED Agar has been used as a non-selective media to perform enantiomeric profiling of quinolones and quinolones resistance gene qnrS in wastewater samples

Preparation Note

Suspend 36.15g in 1000ml distilled water. Boil to dissolve the medium completely. Sterilize by autoclaving at 15 lbs pressure (121°C) for 15 minutes.

Footnote

We offer two media types: the superior granulated GranuCult® and the cost-efficient powdered NutriSelect® culture media, depending on your needs.
The designations basic, plus, or prime are added to indicate the quality control level, from basic quality control to standard QC plus to prime for full regulatory compliance.

MacConkey agar and Cystine-Lactose-Electrolyte-Deficient (CLED) agar, media widely used in the bacteriological laboratory and recommended for the detection of urinary tract infections, were sterilized by gamma-radiation at a dose of 1.5 Mrad. Both were modified and adapted to radiation sterilization

Differentiation and Identification Media for Salmonella

Salmonella contamination is the second leading cause of food-borne illness worldwide. Controlling outbreaks of Salmonella is an important task for food regulators, restaurants and the food industry in general. The Salmonella family includes over 2,300 serotypes of bacteria, but two types, Salmonella enteritidis and Salmonella typhimurium, are responsible for about half of all human infections. Most outbreaks of Salmonella are traced back to dairy, poultry and meat products, but Salmonella can grow on nearly any food. Chicken, eggs and their derivative products are particularly high risk.
