Some of these microbial differences could have clinical significance. This study describes clinical parameters and the composition of the subgingival microbiota in chronic periodontitis (CP) and aggressive periodontitis (AgP) patients in a Colombian population.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> Clinical parameters (probing depth, clinical attachment level, bleeding on probing, and plaque index) and plaque samples from 68 CP, 12 AgP, and 30 periodontally healthy subjects were analyzed. Subgingival samples were processed using culture, biochemical tests, and polymerase chain reaction for the detection of periodontal and superinfecting pathogens. The analysis of variance, \u03c7<jats:sup>2<\/jats:sup>, and Kruskal\u2010Wallis tests were used to evaluate differences between groups for clinical parameters and microbiologic composition (<jats:italic>P<\/jats:italic> \u22640.05).<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> Clinical parameters were significantly increased in CP and AgP patients compared to healthy subjects (<jats:italic>P<\/jats:italic> &lt;0.001), but no differences were found between periodontitis groups. <jats:italic>Porphyromonas gingivalis<\/jats:italic>, <jats:italic>Tannerella forsythensis<\/jats:italic>, and <jats:italic>Eikenella corrodens<\/jats:italic> showed higher frequencies in AgP compared to CP and healthy subjects (<jats:italic>P<\/jats:italic> &lt;0.05). Extension (localized and generalized) of the periodontal destruction had no effect on the composition of the subgingival microbiota.

Gram\u2010negative enteric rods were frequent in AgP and CP patients.
