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.
