Aggregatibacter actinomycetemcomitans serotypes and DGGE subtypes in Thai adults with chronic periodontitis

Highlights • A. actinomycetemcomitans non-serotypeable strains were predominant in Thai patients with chronic periodontitis. • Two strains of A. actinomycetemcomitans had a JP2 like deletion of the leukotoxin gene and, classified as serotype c. • Two strains of A. actinomycetemcomitans had an insert...

Description
Summary:Highlights • A. actinomycetemcomitans non-serotypeable strains were predominant in Thai patients with chronic periodontitis. • Two strains of A. actinomycetemcomitans had a JP2 like deletion of the leukotoxin gene and, classified as serotype c. • Two strains of A. actinomycetemcomitans had an insertion in the leukotoxin gene and, classified as serotype c. • DGGE could classify A. actinomycetemcomitans non-serotypeable strains into 16 subtypes. • Up to 4 subtypes of A. actinomycetemcomitans could be isolated from the same deep periodontal pocket.
