Mutans streptococci (MS) representing eight different serotypes were tested for their ability to coaggregate in vitro with oral actinomyces and other streptococcal species. Of the mutans streptococci tested, only strains of S. cricetus (formerly S. mutans serotype a) displayed pronounced coaggregations and only with certain strains of actinomyces. S. cricetus coaggregated, by lactose nonreversible mechanisms, with serotype 4 Actinomyces naeslundii WVU963 and WVU924 and with serotype 2… 

Coaggregation of Oral Streptococcus milleri

Results suggest that S. milleri, at least strains of serotypes b, e, and f, belongs to streptococcus coaggregation group 2.

Coaggregation of Prevotella intermedia with oral Actinomyces species

Five strains of Prevotella intermedia were examined for their ability to coaggregate with various gram-positive and gram-negative species of oral bacteria and data suggest that all of these coaggregations involve either a protein or glycoprotein on thePrevotella strain, which may interact with carbohydrates or carbohydrate-containing molecules on the surface of the Actinomyces strain.

Porphyromonas gingivalis vesicles promote the coaggregation of mutans streptococci and early colonizers

Whether or not vesicles in the supernatant of P. gingivalis ATCC 33277 promoted the coaggregation of Streptococcus mutans and early colonizers is examined.

Evidence for the existence of two classes of corncob (coaggregation) receptor in Fusobacterium nucleatum.

The results of these experiments provide convincing evidence that at least 2 independent strain-specific receptors on F. nucleatum are involved in corncob formation between this bacterium and S. sanguis.

Adherence of mutans streptococci to other oral bacteria

The observations suggest that the mutans streptococci can adhere to a variety of early plaque bacteria by several distinct mechanisms, which may be important in the colonization of tooth surfaces by the mutan strePTococci.

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

There is evidence that multiple fusobacterial adhesins have a role in the attachment of F. nucleatum to Gram-positive species and at least one additional adhesin that is sensitive to arginine is provided but unlike Fap2 and RadD, is not a member of the autotransporter family type of fUSobacterial large outer membrane proteins.

Dental plaque development on defined streptococcal surfaces.

It is demonstrated that interbacterial coaggregation had only a limited effect on in vivo plaque development, suggesting that environmental factors, growth or other adherence phenomena are dominant in in vitro plaque formation.

Coaggregation Properties of Human Oral Veilionella

Results indicate that the three human oral Veillonella species are distributed on oral surfaces that are also occupied by their coaggregation partners and thus provide strong evidence that coaggregate plays a critical role in the bacterial ecology of the oral cavity.

Lactose-sensitive and -insensitive cell surface interactions of oral Streptococcus milleri strains and actinomyces

Of 158 oral Streptococcus milleri strains, 46 exhibited cellular coaggregation with the reagent strains of the actinomycesCoaggregation groups A, B, and/or E, and S. milleri infrequently exhibits lactose-inhibitable coaggregating with act inomyces.

Coaggregation between Porphyromonas gingivalis and Mutans Streptococci

The results of heat and proteinase K treatment suggested that a heat‐labile proteinaceous substance of P. gingivalis and a heat-stable substance of mutans streptococci may play a role in the coaggregation.



Lactose-reversible coaggregation between oral actinomycetes and Streptococcus sanguis

Most of the coaggregation between freshly isolated oral actinomycetes and streptococci involves lactose-reversible cell-cell interactions, which suggests that such coaggregate is mediated by a network of lectin-carbohydrate interactions between complementary cell surface structures on the two cell types.

Prevalence of viridans streptococci exhibiting lactose-inhibitable coaggregation with oral actinomycetes

It is suggested that these coaggregations are mediated by a network of lectin-carbohydrate interactions similar to those already characterized in previous studies with stock cultures of actinomycetes and streptococci.

New Actinomyces and Streptococcus coaggregation groups among human oral isolates from the same site

Results indicate that nearly all fresh isolates of these species obtained from both diseased and healthy sites exhibit specific, nonrandom patterns of coaggregation and suggest the widespread occurrence of in vivo cell-to-cell recognition between oral actinomyces and streptococci.

Mechanism of coaggregation between Actinomyces viscosus T14V and Streptococcus sanguis 34

Actinomyces viscosus T14V and Streptococcus sanguis 34 coaggregate by a mechanism which is not inhibited by 1 M NaCl, is dextran independent, requires calcium, is pH dependent with an optimum at pH

Coaggregation of human oral Cytophaga species and Actinomyces israelii

A total of 19 strains of oral Cytophaga sp. obtained from subgingival plaque deposits were tested for their ability to coaggregate with strains of Actinomyces israelii, A. viscosus, A. naeslundii,

Interbacterial aggregation of Actinomyces naeslundii and dental plaque streptococci.

Electron microscopic examination of aggregates of untreated bacteria revealed that the attachment between cells of strains 398 A and S was mediated by short tufts of electron-dense fuzzy components of the cell surfaces, which may account for the previously-reported, delayed increase in A. naeslundii proportions among bacteria forming early plaque deposits.

Proposal to Elevate the Subspecies of Streptococcus mutans to Species Status, Based on Their Molecular Composition

It is proposed to confer species rank to the genetically distinct streptococci that have been considered subspecies of Streptococcus mutans Clarke to exclude phenotypically similar bacteria that have deoxyribonucleic acid (DNA) guanine plus cytosine contents appreciably different from 36 to 38 mol% and/or that do not demonstrate DNA base-sequence homology with the type strain.

Role of interbacterial adherence in colonization of the oral cavities of gnotobiotic rats infected with Streptococcus mutans and Veillonella alcalescens

The role of interbacterial adherence in the colonization of the rate oral cavity was investigated with aggregating and nonaggregating strains of Veillonella alcalescens and Streptococcus mutans, indicating that bonding between the organisms was strong.

Inhibitors of coaggregation between Actinomyces viscosus T14V and Streptococcus sanguis 34: beta-galactosides, related sugars, and anionic amphipathic compounds

It is hypothesized that the T14V lectin combining site for Ss34 carbohydrate has specific affinity for beta-galactosides and for anionic nonaromatic amphipathic molecules.

Streptococcus mutans adherence: presumptive evidence for protein-mediated attachment followed by glucan-dependent cellular accumulation.

A two-reaction model of S. mutans adherence was developed and it was confirmed that one reaction is attachment to the tooth pellicle which is mediated by cell-surface proteins rather than glucans or teichoic acids and the other reaction is cellular accumulation mediated by sucrose-derived d-glucans and cell surface lectins.
