Major similarities in the bacterial communities associated with lesioned and healthy Fungiidae corals.

摘要: Cultivation-based studies have demonstrated that yellow-band disease (YBD), a lesion-producing ailment affecting diverse species of coral, is caused by consortium Vibrio spp. This study takes the first cultivation-independent approach to examine whole bacterial community associated with YBD-like lesioned corals. Two Fungiidae corals, Ctenactis crassa and Herpolitha limax, displaying lesions were examined across reefs throughout Red Sea. Using pyrosequencing targeting V1-V3 regions SSU rRNA gene, no major differences in composition or diversity identified between healthy corals either species. Indicator analysis did not find significantly However, operational taxonomic units belonging Ruegeria genus Alphaproteobacteria NS9 marine group Flavobacteria The most striking trend this dataset was reef location found be significant influence on coral-bacterial community. It possible more pronounced lesion-specific signatures might been concealed strong environmental conditions coral-bacteria. Overall, demonstrates inconsistencies cultivation-based regarding role specific bacteria coral diseases.
