Chimeric 16S rDNA sequences of diverse origin are accumulating in the public databases.
A significant number of chimeric 16S rDNA sequences of diverse origin were identified in the public databases by partial treeing analysis. This suggests that chimeric sequences, representing phylogenetically novel non-existent organisms, are routinely being overlooked in molecular phylogenetic surveys despite a general awareness of PCR-generated artefacts amongst researchers.
