Question about Bacteria and Teeth- 10 Points?

I would say D..

Various mechanisms for plaque formation have been

considered, such as the acid precipitation (61), the enzyme precipitation (199), and nonselective (279, 309) or selective

(106, 113, 147) microbial adherence theories. Of these, the

concept of selective adherence via specific ionic (106),

hydrophobic (262), and lectinlike (113, 308) interactions is

best able to explain the initial colonization of the AEP by

Streptococcus sanguis and S. mitis (106). Subsequent attachment

of other bacteria involves a variety of specific

coaggregation reactions of which those involving

Actinomyces viscosus or A. naeslundii with S. sanguis are

the best described (49). The MS are not particularly good

colonizers of the tooth surface (342), sothat their emergence

as dominant plaque species needs to be explained by mechanisms

other than a high affinity for receptors on the AEP.

Among these would be the ability to synthesize adherent

glucans from sucrose (110, 131, 308) and the ability to

survive in the microenvironment created by the topography of that particular tooth surface.
