Genetic structure of populations of Porphyromonas gingivalis associated with periodontitis and other oral infections.

Infection and immunity - 1 Jan 1993

Loos B G, Dyer D W, Whittam T S, Selander R K

Abstract excerpt

One hundred isolates of the oral pathogenic bacterium Porphyromonas gingivalis were genetically characterized by determining the electrophoretic mobilities of 16 metabolic enzymes and the presence or absence of catalase activity. A total of 78 distinct electrophoretic types (ETs), representing multilocus genotypes, were identified, and cluster analysis placed them in three major phylogenetic divisions. Division I...
