[Dry medium for isolating Clostridium perfringens].
The possibility of using blood substitutes (hydrolysin, casein hydrolysate "tsolipk" and amino peptide) with expired shelf life as a culture medium for the isolation of Cl. perfringens has been studied. Dry culture medium based on these inedible products has been developed. To stimulate bacterial growth, fodder yeast extract has been used. The suppression of the growth of extraneous microflora is ensured by the use of antibiotics: polymyxin sulfate and mycerin sulfate. The recommended medium is not inferior in its quality (sensitivity, rapidity of growth, differentiating and inhibiting properties, etc.) to media based on meat and casein. The use of the newly developed medium is economically grounded and allows one to obtain standard results.
