Detection of faecal streptococci

Faecal streptococci are able to grow in the presence of sodium azide (NaN3), while many other types of bacteria are inhibited or killed by azide. Thus, by using culture mediums containing azide, it is possible to [Pg.638]

The quantity of water to be tested is filtered through a membrane filter with a pore size of 0.43 pm. The membrane filter is placed on a special [Pg.638]

Faecal streptococci are gram-positive oval to lance-shaped diplococci or short-chain streptococci. [Pg.638]

Faecal streptococci must grow both in a nutrient broth whose pH has been set to 9.6, as well as in a nutrient broth which contains 6.3 % common salt (normal nutrient groth contains 0.3 % common salt). Incubation [Pg.638]

If necessary, determination of the exact type can be carried out with the diagnosis strips (e.g. API-Strep) which are commercially available, or in accordance with the following table. [Pg.638]
