The effect of 0.01, 0.02, 0.03, 0.05, 0.6, 0.8 and 0.9% of polyphosphate mixture on 5 strains of Streptococcus agalactiae, 2 strains of Streptococcus dysgalactiae and 3 strains of Steptococcus uberis in blood agar in vitro and in milk was examined. It was found that the growth of all strains of the above mentioned bacteria was completely inhibited by 0.03% phosphate mixture in blood agar. In milk, however, the amount of polyphosphate mixture necessary for total inhibition was, from 0.6 to 0.9%, depending on the strain.
