1. The presence of agents capable of attacking hyaluronic acid, chondroitin sulfate, and a collagen preparation have been demonstrated in bacteria-free filtrates prepared from gingival deposits obtained from individuals with various degrees of gingival inflammation.

2. The active substances were not found in filtrates prepared from gingival deposits removed from individuals with clinically normal gingiva.

3. Histamine could not be detected in extracts of gingival deposits from patients with gingivitis or in extracts of inflamed gingival tissue.

4. Several microorganisms isolated from gingival pockets of individuals with gingivitis were shown to be capable of producing hyaluronidase and collagenase.

5. A discussion about a possible role of bacteria in gingivitis is given.
