Comments P.169 left column: "16S rRNA gene library construction using universal bacterial PCR primers revealed a common microbial signature in many sponges that is phylogenetically complex yet highly sponge-specific and distinctly different from that of marine plankton (Fig. 4). 16S rRNA gene phylotypes affiliated with the phyla Acidobacteria, Chloroflexi, Actinobacteria, Proteobacteria (Alpha-, Gamma-, Delta-), Nitrospira, Cyanobacteria, and Bacteriodetes, as well as a cluster of uncertain affiliation now recognized as the Gemmatimonadetes (U. Henschel, unpublished data) were recovered by this approach. In addition, a crenarchaeal lineage was documented in Axinella mexicana and other axinellid sponges (Preston et al., 1996 Margot et al., 2002), and a new eubacterial candidate phylum ‘Poribacteria’ was recently discovered in verongid sponges (Fieseler et al., 2004). The fact that the apparently sponge-specific phylotypes are present below detection levels or may even be absent from seawater, sediment and other environments indicates highly selective conditions for microbial existence within the sponge mesohyl."
