Association of nine pathobionts with periodontitis in four South American and European countries

Abstract

Unlike prevalence, relative load was found to be a reliable variable to discriminate the association of the species with periodontitis. Based on this, <i>F. alocis, P. endodontalis, P. gingivalis, T. denticola</i> and <i>T. forsythia</i> may be biomarkers of disease in Belgium, Chile and Spain, due to their significantly higher abundance in periodontitis patients.
