Summary
-
1.
An examination of 200 strains of aquatic streptococci has shown that the conversion of citrate provides a good complementary criterion for the detection of faecal streptococci as prescribed in the “Normblad” N 3043. Especially when the result on tellurite agar does not present a clear picture, owing to the colour of the colonies being grey instead of a deep black, the citrate test helps to reach a decision.
-
2.
An examination of 55 known enterococcus-strains has shown that the conversion of sodium citrate gives positive results for:Streptococcus faecalis and its variants and for some strains ofStreptococcus faecium. On the other hand negative results are found forStreptococcus bovis enStreptococcus durans.
