“…Although PGP-LTA synthesis was found to be widespread among the species examined, strains of both S. rnitis and S. oralis were exceptional in this respect, which supports the results of previous studies of PGP-LTA synthesis in oral streptococci (17,32) and is consistent with the results of more detailed taxonomic studies which have shown that these organisms are closely related to Streptococcus pneumoniue. Thus, S. mitis, S. oralis, and S. pneumoniae form a small cluster, which exhibits 99% 16s rRNA sequence homology, within a larger cluster termed the mitis group, which also contains Streptococcus gordonii, S. sanguis, and Streptococcus parasanguis (25).…”

“…Previously, Rosan (32) and Hamada et al (17) showed that Streptococcus mitis and Streptococcus sanguis biotype I1 (also previously known as biotype B) do not synthesize PGP-LTA. However, since these studies there have been profound changes in the classification of oral streptococci, including emended descriptions of some species and descriptions of a number of new species, such as S. mitis and S. sanguis (for a review see reference 19).…”

“…Histologic studies have also been conducted on odontoblast apoptosis in the pulp cavity due to aging (14), by examining physiological apoptosis in healthy dental pulp at various developmental stages (15), and by observing physiological apoptosis and macrophage phagocytosis of apoptotic bodies (16). More recently, it has been found that a number of bacteria, irrespective of their gram-stain classification (positive or negative), can induce apoptosis and that the associated endotoxins from bacteria, in addition to other metabolites including exotoxin, can bring about apoptosis (17)(18)(19)(20)(21). It remains unclear, however, whether the influence of S. mutans on the dental pulp cells includes apoptosis.…”

“…Partially characterized lipoglycans have been detected in some streptococci and actinomycetes. Streptococcus sanguis biotype B strains lack LTA (22,43), and low yields of a lipoheteropolysaccharide containing glucose, galactose, mannose, glycerol, and fatty acids have been recovered from S. sanguis ATCC 10557 (69). Actinomyces viscosus NY1 contains a fatty acylated heteropolysaccharide of mannose, glucose, and galactose which is substituted with glycerophosphate, N-acetylglucosamine, lysine, and alanine and has an overall anionic charge (66 LTA has been proposed to regulate cell wall autolysins.…”
