Survival of human dental plaque flora in various transport media.
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. Expand
Bacteriology of human experimental gingivitis: effect of plaque age.
Twenty-five subjects with previously excellent hygiene and healthy gingiva developed heavy plaque accumulations and bleeding or nonbleeding gingivitis about certain papilla after 21 days of no oral hygiene and the shift from a Streptococcus-dominated plaque to an Actinomyces- dominated plaque was the most striking microbial change observed as the plaque aged.

Bacterial profiles of subgingival plaques in periodontitis.
The data indicate that the various types of periodontitis, with the possible exception of LJP, are specific anaerobic infections involving spirochetes and to a lesser extent B. gingivalis and B. intermedius. Expand
The viability of microorganisms in carious lesions five years after covering with a fissure sealant.
- R. Going, W. J. Loesche, D. Grainger, S. Syed
- Journal of the American Dental Association
- 1 September 1978
Data confirm and extend previous observations that a limited number of cultivable organisms persist in some lesions but their numbers are few, and they do not appear capable of continuing the destruction of tooth structure. Expand
The predominant cultivable dental plaque flora of beagle dogs with gingivitis.
The predominant dental plaque flora of 15 female beagle dogs with naturally developed gingivitis was studied using a continuous anaerobic culturing technique and showed that the total viable CFU and the proportions of Gram positive organisms were significantly higher in the supra- than the subgingival plaque.

Puberty gingivitis in insulin-dependent diabetic children. I. Cross-sectional observations.
- F. Gusberti, S. Syed, G. Bacon, N. Grossman, W. J. Loesche
- Journal of periodontology
- 1 December 1983
This cross-sectional study examined the gingivitis occurring at puberty in a population of insulin-dependent juvenile diabetics, suggesting that a specific bacterial shift in the microbial composition of marginal plaque occurs in response to host changes in juvenile diabetic children at this age period.

Efficiency of various growth media in recovering oral bacterial flora from human dental plaque.
It is suggested that MM10 SB agar is an ideal culture medium for the isolation, nonselective enumeration, and differential counts of bacteria present in normal and disease-associated plaques. Expand
An endo-acting proline-specific oligopeptidase from Treponema denticola ATCC 35405: evidence of hydrolysis of human bioactive peptides.
The ready hydrolysis of human bioactive peptides at bonds involving an imino acid residue suggests that enzymes like POPase may contribute to the chronicity of periodontal infections by participating in the peptidolytic processing of those peptides. Expand
The predominant cultivable flora of tooth surface plaque removed from institutionalized subjects.
The overall character of these plaque isolates suggested that a gingival crevice microflora containing several amino-acid fermenting species had colonized the tooth surfaces, which might explain why these subjects had a low caries experience. Expand
