PP0080 – CLED Agar
This is one such medium and has been developed with the aim of simplifying the differentiation and presumptive identification of the main organisms usually found in Urinary Tract Infections. This page was last edited on 24 Decemberat The presence of important contaminants such as diphtheroidslactobacilli and micrococci is also clearly elicited, giving an indication of the degree of contamination.
CM Recommended for diagnostic urinary bacteriology. These techniques overcome false bacteriological results associated with delay in the transport of the specimens of urine to the laboratory and permit a clinically accurate routine differential viable count.
October Learn how and when to remove this template message. Non-lactose fermenting strains – blue colonies. It contains cystine and lactose and is electrolyte -deficient; the latter trait prevents the swarming of Proteus species.
Streptococcus pyogenes and many other fastidious organisms that do not require the presence of blood can grow on this medium. Retrieved 18 October Alphaproteobacteria Brucella Brucella agar Farrell’s medium.

Mix well before pouring. Material Safety Data Sheet. Firm Gel Side 2: Lactose-positive bacteria build yellow colonies. Growth Characteristics on CLED Medium 18 hours incubation Escherichia coli yellow, opaque colonies with a slightly deeper coloured centre about 1.
Pale green coloured, free-flowing powder Prepared medium: Commons is a freely licensed media file repository. This medium is recommended for urinary bacteriology, supporting the growth of all urinary pathogens and giving good colonial differentiations and clear diagnostic characteristics. The lack of electrolytes inhibits the spreading of Proteus spp. Cystine is also present to benefit those organisms that have a particular Cystine requirement.

Quality Control Test Organisms: Non-lactose fermenting strains – blue colonies Klebsiella species extremely mucoid colonies varying in colour from yellow to whitish-blue Proteus species translucent blue colonies usually smaller than Escherichia coli Salmonella species flat blue colonies Pseudomonas aeruginosa green colonies with typical matt surface and rough periphery Enterococcus faecalis yellow colonies about 0.
Public domain Public domain false false. Recent developments in culture media have given rise to the use of chromogenic substrates as dled means of differentiating bacteria particularly among the coliform group of organisms. This file contains additional information, probably added from the digital camera or scanner used to create or digitize it.
Two chromogens are present in the medium, one allows the detection of enterococci giving rise to blue colonies whilst the second results in purple colonies of E. Permission Reusing this file. The medium supports the growth of all urinary potential pathogens giving good colonial differentiation and clear diagnostic characteristics.
