High Sucrose

22 monkeys were randomly allocated to one or other of 2 communes and fed a caries-promoting high sucrose diet. After 28 weeks commune 1 (13 monkeys) was found to harbour Streptococcus mutans serotype e as the predominant streptococcal species, but no monkey in commune 2 harboured this serotype. Instead the 9 monkeys of commune 2 harboured Streptococcus mutans serotypes c and h and had a greater proportion of Streptococcus mitior and Streptococcus milleri in their dental plaque. The significance of these observations on the use of monkeys as a model of human dental caries is discussed.

Wall Ultrastructure

During the almost 50 years since Streptococcus mutans was first suggested as a factor in the etiology of dental caries, a multitude of studies have confirmed the cariogenic potential of this organism. Streptococci have been isolated from human and animal caries on numerous occasions and, with few exceptions, they are not typable by the Lancefield technique but are relatively homogeneous in their biochemical reactions. An analysis of the guanine-cytosine (G-C) composition of the DNA from strains K-1-R, NCTC 10449, and FA-1 by one of us (ALC) revealed significant differences and DNA-DNA reassociation experiments indicated that genetic heterogeneity existed among the three strains. The present electron microscopic study had as its objective the elucidation of any distinguishing morphological characteristics which might further characterize the respective strains.
