| Popis: |
The comparative study of different protein bases has shown that the combined base containing animal blood hydrolysate (amino peptide) and acidic casein hydrolysate, moderately cleaved, in the proportion 1:1 is a good source of nitrogen and ensures the intensive growth of streptococci. As determined by the study of the physiological parameters and growth of streptococci, the presence of fodder yeast extract, glutamine, glucose and phosphates in media containing blood hydrolysate and casein hydrolysate has been found to render a stimulating effect on the growth and multiplication of these organisms. The data thus obtained have been used as the basis for developing the formula of a dried culture medium, capable of ensuring the growth of streptococci without blood or serum added and not inferior in its quality to Todd-Hewitt Broth manufactured by Oxoid Ltd. (Great Britain) and Difco Laboratories (USA). The physico-chemical and physiological characteristics of the proposed medium have been determined. The use of the new dried culture medium in medical practice will make it possible to improve the microbiological diagnosis of streptococcal infections. |
