Table 2 Conserved bacterial ASVs present in > 30% of coral samples (n = 51) and present in at least 5 out of 7 coral species. When an ASV sequence is a 99–100% match to the representative OTU sequence from Table 1, it is identified in parentheses

From: Microbiomes of stony and soft deep-sea corals share rare core bacteria
