title: [Studies of oral microbiogenesis. II. Significance of staphylocci present in periodontal lesions, pulp gangrene and in the alveolus after tooth extraction].
abstract: A study was carried out on the properties and significance of staphylococci isolated from the alveoli after dental extraction (12 strains), from parodontal pus (19 strains) and pulpar gangrene (15 strains). By their frequency, staphylococci of the Staphylococcus aureus have an etiologic significance in pulpar gangrene. Of particular importance for the diagnosis and epidemiology was the predominance of lysotype 80 among the staphylococci isolated from pulpar gangrene and lysotype 77 in healthy carriers. In 2 of 11 patients the coexistence of the same lysotype was found in the pulpar gangrene and nasal secretion.
