Actinobacillus actinomycetemcomitansgenetic heterogeneity: amplification of JP2-likeltxpromoter pattern correlated with specific arbitrarily primed polymerase chain reaction (AP-PCR) genotypes from human but not marmoset Brazilian isolates

Canadian Journal of Microbiology, 2002
Specific clonal types of Actinobacillus actinomycetemcomitans, a major human periodontal pathogen, may be responsible for clinical manifestations and the production of leukotoxin virulence factors. Leukotoxicity is associated with genetic polymorphism at the promoter region of the leukotoxin (ltx) gene.

Progression of attachment loss is strongly associated with presence of the JP2 genotype of Aggregatibacter actinomycetemcomitans: a prospective cohort study of a young adolescent population

Journal of Clinical Periodontology, 2014
AbstractAimTo assess the progression of attachment loss (AL) during a 2‐year period according to the presence of JP2 and non‐JP2 genotypes of Aggregatibacter actinomycetemcomitans in a Ghanaian adolescent population.MethodsA total of 500 adolescents (mean age 13.2 years, SD ± 1.5) were enrolled in the study.

Leukotoxic potential among JP2 and non-JP2 genotypes of Aggregatibacter actinomycetemcomitans

2019
Background and Aim: Periodontitis is a disease causing destruction of the periodontal connective tissue and bone supporting the teeth. Presence of the JP2 genotype of Aggregatibacter actinomycetemcomitans (Aa) in periodontal pockets is associated with a high risk of development of periodontitis in adolescents.
