TL;DR: periodontal pathogens are present in atherosclerotic plaques where, like other infectious microorganisms such as C. pneumoniae, they may play a role in the development and progression of atherosclerosis leading to coronary vascular disease and other clinical sequelae.

TL;DR: This study suggests that localized juvenile and other forms of Actinobacillus-associated periodontitis are primarily associated with the highly leukotoxic clone of A. actinomycetemcomitans.

TL;DR: Data support the hypothesis of differences between populations in the prevalence of periodontopathic bacteria and of greater attachment loss in sites infected with highly leucotoxic A. actinomycetemcomitans in Brazilians with aggressive or chronic periodontitis.

TL;DR: Subjects with halitosis harbor some bacterial species on their dorsal tongue surfaces that are distinct from bacterial species found in control subjects, consistent with the hypothesis that hal itosis has a microbial etiology.

TL;DR: Patients with localized juvenileperiodontitis were shown to have a substantially higher prevalence of highly leukotoxic strains than healthy individuals or those with adult periodontitis, and data point to the importance of specific A. actinomycetemcomitans strains, as characterized by their expression of high levels ofLeukotoxin, in the pathogenesis of certain types of early-onset periodontococcal diseases and, possibly, other forms of rapidly progressing Periodontitis.
