CLED agar, or Cystine-Lactose-Electrolyte-Deficient agar, is a culture medium primarily used for the isolation and differentiation of urinary pathogens, particularly bacteria like Escherichia coli and Enterococcus spp. It is designed to support the growth of most urinary tract infection (UTI) pathogens while inhibiting the growth of some non-pathogenic organisms. The agar contains lactose, which allows for lactose fermentation detection, changing the color of colonies, and aiding in the identification of lactose fermenters versus non-fermenters. Its electrolyte-deficient formulation minimizes swarming of Proteus species, making it easier to identify other bacteria in urine samples.
What else can I help you with?
Why is urine specimen is inoculated on cled?
Urine specimens are inoculated on CLED (cysteine lactose electrolyte deficient) agar because this medium supports the growth of most urinary pathogens while inhibiting the growth of normal urinary flora. It allows for the differentiation of different bacterial species based on colony characteristics and lactose fermentation. CLED agar is also able to identify the presence of UTI-causing organisms such as E. coli, Proteus, and Enterococcus.
Can enterococci grow on CLED medium?
Yes, enterococci can grow on CLED (Cystine Lactose Electrolyte Deficient) medium. CLED is designed to support the growth of a wide variety of urinary tract pathogens, including enterococci, while inhibiting the growth of certain contaminants. It allows for the differentiation of lactose fermenters from non-fermenters, which can help in identifying enterococci in clinical samples.
How many teaspoons is 7 g agar agar powder?
Approximately 2 teaspoons of agar agar powder is equivalent to 7 grams.
From which organism agar agar is extracted?
red algae Agar agar is a malay term meaning red algae. This algae which agar is extracted lives in the ocean around Malaysia
Is there a microorganism that degrades Agar agar?
Yes, some marine bacteria and fungi have been identified to possess the capability to degrade agar agar. These microorganisms secrete enzymes such as agarases that breakdown agar into simpler sugars, which they can then use as a source of energy.

Lab run out froom blood agar and cled plate what to do?
Depends on specimens you are inoculating - given CLED was mentioned I would assume urines. Standard set of PIM for a urine is HBA, MAC and CLED (although some labs omit the CLED). Most commonly encountered organisms in a UTI are enterobacteriaceae, especially E. coli; and other gram negative rods such as Pseudomonas. Can encounter Staphylococci and some other gram positive organisms - especially in hospital settings. Personally, in this situation I would use a CNA, Choc and MAC for urines - CNA grows the staphylococci (and streptococci and enterococci); Choc provides a non-selective media and MAC grows the gram negative rods that are most frequently isolated. Also, if nothing WAS isolated possibly release results with a comment about the accuracy of the results given the inavailbility of blood agar. Cled is useful for swarming proteus, to isolate them - I would attempt to isoalte and ID proteus without a CLED if necessary, if not put the plates aside (fridge) until a new supply of CLED can be brought in - if this will occur rapidly. If it will take longer consider shipping these specimens to another laboratory.
Can enterococci grow on CLED medium?
Yes, enterococci can grow on CLED (Cystine Lactose Electrolyte Deficient) medium. CLED is designed to support the growth of a wide variety of urinary tract pathogens, including enterococci, while inhibiting the growth of certain contaminants. It allows for the differentiation of lactose fermenters from non-fermenters, which can help in identifying enterococci in clinical samples.
