Neogen® Cystine Lactose Electrolyte Deficient (CLED) Agar

Cystine Lactose Electrolyte Deficient (CLED) Agar is used for the differentiation and enumeration of microorganisms in urine. A medium for urine culture where the absence of electrolytes inhibits the swarming of Proteus spp. Cystine is added for the benefit of those organisms which have a specific cystine requirement. Differentiation of lactose and non-lactose fermenters is achieved using bromothymol blue as pH indicator. This medium supports the growth of Streptococcus pyogenes and most other fastidious organisms that do not require blood.
