CLED medium is preferred over MacConkey for culture of organisms implicated in urine infection. The reason is:: (A) It prevents swarming of Proteus, (B) Differentiate LF and NLF, (C) Promote growth of Staphylococcus, Streptococcus and Candida, (D) Identifies Pseudomonas
Answer is C. Ans. C. Promote growth of Staphylococcus, Streptococcus and CandidaCLED Agar: Cysteine Lactose Electrolyte deficient agar. It is similar to MacConkey agar for differentiation of LF and NLF which can be used as a good alternate to combination of blood agar and MacConkey ager for processing of urine specimens with certain advantages over MacConkey agar (supports growth of Gram positive cocci (except B hemolytics Streptococci) and Candida over blood agar (prevents swarming of Proteus).
