Department of Odontology Umeå University 2013 Exotoxins of Aggregatibacter actinomycetemcomitans and periodontal attachment loss in adolescents Carola Höglund Åberg History Aggregatibacter actinomycetemcomitans was first reported in a publication by Klinger in 1912 who termed it as Bacterium actinomycetemcomitans which was changed to Bacterium comitans by Lieske, and finally to Actinobacilius actinomycetemcomitans by Topley and Wilson. Actinobacillus actinomycetemcomitans is one of the most completely studied periodontal bacteria. xڽYI��6��W�(�`lH�Ǟ��'���$Zb�Eå�=�~ The JP2 clone has an approximately 530-bp deletion (∆530) in the promoter region of the lkt/ltx gene, which encodes leukotoxin, and this clone has high leukotoxic activity.
