Bacteria associated with an encrusting sponge (Terpios hoshinota) and the corals partially covered by the sponge.

Terpios hoshinota, a dark encrusting sponge, is known to be a competitor for space in coral reef environments, and facilitates the death of corals. Although numerous cyanobacteria have been detected in the sponge, little is known of the sponge-associated bacterial community. This study examined the sponge-associated bacterial community and the difference between the bacterial communities in the sponge and the coral partially covered by the sponge by analysis of 16S rRNA gene sequences of samples isolated from the sponge covering the corals Favia complanata, Isopora palifera, Millepora sp.
