title: Occurrence of haemophili in dental plaque and their association with neuraminidase activity.
abstract: The mean concentration of haemophili in 31 specimens of plaque was 1.23 times 10(6) per milligram or approximately 4.4% of the viable bacteria present. Occurrence of different species was similar to saliva with Haemophilus parainfluenzae constituting 87.8%. Most haemophili produced neuraminidase and appeared to be primarily responsible for the small amounts of this enzyme in plaque.
