“…It was also found that prevotellae and streptococci were the genera that most often coaggregated with multiple bacterial species in the present study (Table 3). This finding is in agreement with previous studies, which showed that streptococci and prevotellae (previously Bacteroides) are widely recognized as coaggregation partners by other species (3,16,19,20). However, coaggregation between streptococci and staphylococci has never been reported before.…”

“…These were also isolated from a relatively high number of the subjects and in high proportion after P. intermedia (table 4). These organisms have been shown to play an important role in the formation of dental plaque through their ability to extensively coaggregate with many other oral microorganisms [13][14][15][16][17]. Since supragingival plaque can harbor putative periopathogens, as demonstrated in this study, it is conceivable to speculate that it probably plays an important role as a reservoir for such organisms and consequently may lead to the spread to, or reinfection of, subgingival sites [18].…”

Objective: To investigate the bacterial flora of the gingival plaques of pediatric dental patients in order to establish baseline data for future studies on the complex microbiota of the oral cavity of this group of child dental patients. Subjects and Methods: Forty subjects, aged 3–12 years, were enrolled and investigated after informed consent was obtained. During the patients’ first visit to the dental clinic supragingival plaque samples were collected from the gingival area of buccal and lingual tooth surfaces of all primary and permanent molar teeth using sterile curettes. Serially diluted samples were inoculated onto a set of selective and nonselective media and then incubated at the appropriate atmospheric conditions and temperatures. Representative colonies of isolates were identified by standard methods, including hemolytic characteristics on blood agar and profiling on API 20S and API 20A as appropriate. Results: A total of 183 isolates (123 aerobes and 60 anaerobes) were recovered from the 40 patients with a mean count of 3 per sample of aerobes compared to 1.5 per sample for the anaerobes. Streptococcus sanguis was the predominant aerobic species (23.6%) isolated from 29 (72.5%) of the 40 patients, followed by Streptococcus mitis, 19.5 and 60%, Streptococcus salivarius, 17.1 and 52.5% and Streptococcus mutans, 17.1 and 52.5%. The frequency of isolation of anaerobic bacteria was Prevotella spp. 50% from 30 (75%) of the 40 patients, Fusobacterium spp., 18.3 and 27.5%, Bacteroides spp., Porphyromonas spp. and Peptostreptococcus spp., 6.7 and 10%, 6.7 and 10%, and 5 and 7.5%, respectively. Prevotella intermedia was the single most common species. Conclusion: The results show that there were more aerobic/facultative anaerobic bacteria than the obligate anaerobes in the dental plaque of the pediatric dental patients in Kuwait. The high prevalence of the pioneering streptococci as well as black-pigmented Prevotella spp. and Fusobacterium spp. indicates that the dental plaques of the children were in the developing stage, a precursor to the development of periodontal diseases.

“…2, 26, 46 Other studies describe similar phenomena of strain-specific interactions for Actinomyces species with different Streptococci 25, 28 as well as a number of additional oral bacterial species. 29, 30, 47 In addition to Fap2, several adhesins involved in some of these interactions have been identified including SspA/B in the binding of S. gordonii with P. gingivalis 48 and the fusobacterial RadD in the interaction between F. nucleatum and Streptococcal species as well as Actinomyces . 13 However, most studies have only investigated individual strains for each of the species involved and comprehensive studies including multiple isolates are still lacking.…”

“…Previous studies of different oral bacterial interactions have demonstrated that coaggregation involves highly specific cell-to-cell recognition of distinct isolates of a certain species and that this pattern is not generalizable to all strains of a single species or all species of a genus. Other examples of these differential binding specificities include Actinomyces naeslundii with different strains of Streptococcus sanguinis and Streptococcus gordonii , 25, 27, 28, 29 P. gingivalis binding with Veillonella, Capnocytophaga and Actinomyces but not with Streptococcus , 30 intra- and intergenic coaggregations between Streptococcus and Actinomyces 31 among others.…”

Characterization of Fusobacterium nucleatum ATCC 23726 adhesins involved in strain-specific attachment to Porphyromonas gingivalis

Bacterial adherence is an essential virulence factor in pathogenesis and infection. Fusobacterium nucleatum has a central role in oral biofilm architecture by acting as a bridge between early Gram-positive and late Gram-negative colonizers that do not otherwise adhere to each other. In this study, we survey a key adherence interaction of F. nucleatum with Porphyromonas gingivalis, and present evidence that multiple fusobacterial adhesins have a role in the attachment of F. nucleatum ATCC 23726 to P. gingivalis in a highly strain-dependent manner. Interaction between these species displayed varying sensitivities to arginine, galactose and lactose. Arginine was found to hamper coaggregation by at least 62% and up to 89% with several P. gingivalis strains and galactose inhibition ranged from no inhibition up to 58% with the same P. gingivalis strains. Lactose consistently inhibited F. nucleatum interaction with these P. gingivalis strains ranging from 40% to 56% decrease in coaggregation. Among the adhesins involved are the previously described Fap2 and surprisingly, RadD, which was described in an earlier study for its function in attachment of F. nucleatum to Gram-positive species. We also provide evidence for the presence of at least one additional adhesin that is sensitive to arginine but unlike Fap2 and RadD, is not a member of the autotransporter family type of fusobacterial large outer membrane proteins. The strain-specific binding profile of multiple fusobacterial adhesins to P. gingivalis highlights the heterogeneity and complexity of interspecies interactions in the oral cavity.
