Thermo Scientific™ Columbia CNA Agar with Sheep Blood Medium

Description

Isolate Gram-positive organisms from clinical samples with this selective media traditionally used to identify staphylococci, streptococci, and S. pneumoniae.

Effectively isolate Gram-positive organisms from clinical samples using Thermo Scientific™ Columbia CNA Agar with Sheep Blood, a selective microbiological medium that includes colistin and nalidixic acid to inhibit gram-negative bacilli. Columbia CNA Agar has traditionally been used to identify staphylococci and streptococci. The addition of sheep blood to the medium allows distinct identification of S. pneumoniae through the production of clear alpha-haemolysis.

Columbia CNA Agar with Sheep Blood contains antibiotics to inhibit S. albus and Micrococcus species as well as Gram-positive and Gram-negative rods. It suppresses growth of Proteus, Klebsiella and Pseudomonas species while permitting unrestricted growth of S. aureus, haemolytic streptococci and enterococci. This medium enables important Gram-positive cocci to be recognised more readily and isolated easily from the mixed bacterial populations contained in many clinical specimens and foods.
