Black‐pigmented Bacteroides from clinically characterized periodontal sites
TLDR
Gingival sites were clinically evaluated on the basis of gingival color and contour, pocket depth, bleeding upon probing and peercent bone loss as measured radiographically.Abstract:
Gingival sites were clinically evaluated on the basis of gingival color and contour, pocket depth, bleeding upon probing and peercent bone loss as measured radiographically. Using anaerobic techniques, subgingival plaque collected from these sites was examined for the presence of the black-pigmented Bacteroides (BPB). The BPB were identified by biochemical testing and Gram stain morphology. With one exception, only saccharolytic strains (B. melaninogenicus) were found at normal and gingivitis sites, while these and asaccharolytic strains (B. asaccharolyticus) were found at sites exhibiting bone loss.read more

The bacterial etiology of destructive periodontal disease: current concepts.
TL;DR: Current data suggest that pathogens are necessary but not sufficient for disease activity to occur, and the local environment of the periodontal pocket may be important in the regulation of expression of virulence factors by pathogenic species.

TL;DR: Monitoring these bacteria in advanced periodontal lesions may greatly assist the assessment of treatment efficacy and risk of further periodontAL breakdown.

Survival of human dental plaque flora in various transport media.

TL;DR: It is suggested that RTF is a satisfactory medium for the transport of oral bacteria present in the samples and VMG II showed a higher recovery of organisms from these specimens with an increase in the storage period, suggesting multiplication of the plaque flora.

Microbiology of Periodontal Disease—Present Status and Future Considerations
TL;DR: There is sufficient evidence that microorganisms play a primary role in the etiology of most forms of human periodontal disease, and the question is no longer whether organisms cause periodontals but rather are specific organisms responsible for specific disease forms.

The predominant cultivable microflora of advanced periodontitis.
TL;DR: A study on the predominant cultivable microorganisms harbored in the base of deep periodontal pockets of eight patients aged 34-48 years was carried out using the roll tube culture technique, and some periodontopathic potentials of the predominating Gram-negative rods are summarized.

Isolation of anaerobic bacteria from human gingiva and mouse cecum by means of a simplified glove box procedure.
TL;DR: Comparative studies indicate that the conventional anaerobic jar method was inadequate for the isolation of strict anaerobes from human gingival specimens and from the mouse cecum.

Attachment of Bacteroides melaninogenicus subsp. asaccharolyticus to Oral Surfaces and Its Possible Role in Colonization of the Mouth and of Periodontal Pockets
Jørgen Slots,R.J. Gibbons +1 more
TL;DR: The presence of dental plaque containing Actinomyces and other gram-positive bacteria may be essential for the attachment and colonization of B. melaninogenicus cells after their initial introduction into the mouth and its subsequent colonization in periodontal pockets.
