Colonization of the Subgingival Area by Bacteroides gingivalis
TL;DR: Since the crevice area is influenced by gingival fluid, the nature of specific antibody and the other affecting components should be considered collectively with the interaction between new predominant colonizers and other pre-existing residents.

Purification and Properties of a Bacteriocin-Like Substance (Acnecin) of Oral Propionibacterium acnes
Setsuo Fujimura,Takeshi Nakamura +1 more
TL;DR: The action spectrum of acnecin was very narrow; it was effective only against strains of non-acnecin-producing P. acnes and Corynebacterium parvum, a species closely related to P. Acnes.

Bacteroides heparinolyticus sp. nov. Isolated from Humans with Periodontitis
TL;DR: A new species of nonpigmented, saccharolytic Bacteroides, Bactroides heparinolyticus, which is frequently isolated from human periodontitis lesions, is described, which produces an enzyme that hydrolyzes heparin.
Comparative properties of envelope-associated arginine-gingipains and lysine-gingipain of Porphyromonas gingivalis
TL;DR: Two arginine specific proteinases and a lysine specificproteinase were purified from materials of the envelope of Porphyromonas gingivalis solubilized by a detergent by the sequential procedures of ion-exchange chromatography, affinity chromatography and isoelectric focusing.

Binding of hemoglobin to the envelope of Porphyromonas gingivalis and isolation of the hemoglobin-binding protein.
TL;DR: It is hypothesized that hemoglobin-binding protein (HbBP), responsible for the binding to hemoglobin, exists in the envelope and confirmed its presence by dot blot determination with peroxidase-conjugated hemoglobin and isolate HbBP from the solubilized materials of the envelope by affinity chromatography.
