Extract

A number of strains of streptococci falling into serological group N which could not be identified as either Streptococcus lactis or Str. cremoris were isolated during a study of the bacterial flora of raw milk (1). These organisms were dominant in milk incubated at 22°C. until the end-point of the clot-on-boiling test in three out of the twelve samples examined and, apparently, had played a major part in their spoilage. Similar strains were isolated in smaller numbers from the samples aged under other temperature conditions.
