This study aimed to estimate the bacterial diversity in the lesions and in control mucosa in pooled samples using a culture\u2010independent molecular approach.<\/jats:p><jats:p><jats:bold>Methods:\u2002<\/jats:bold> Samples were collected from ten healthy individuals and ten individuals with a clinical history of recurrent aphthous ulcers. After DNA extraction, the 16S ribosomal RNA bacterial gene was amplified by polymerase chain reaction with universal primers; amplicons were cloned, sequenced and matched to the GenBank database.<\/jats:p><jats:p><jats:bold>Results:\u2002<\/jats:bold> A total of 535 clones were analyzed, defining 95 bacterial species. We identified 62 putative novel phylotypes. In recurrent aphthous ulcer lesions 57 phylotypes were detected, of which 11 were known species. Control samples had 38 phylotypes, five of which were already known. Only three species or phylotypes were abundant and common to both groups (<jats:italic>Gemella haemolysans<\/jats:italic>, <jats:italic>Streptococcus mitis<\/jats:italic> strain 209 and <jats:italic>Streptococcus pneumoniae<\/jats:italic> R6).
