| molecular detection and ecological significance of the cyanobacterial genera geitlerinema and leptolyngbya in black band disease of corals. | black band disease (bbd) is a pathogenic, sulfide-rich microbial mat dominated by filamentous cyanobacteria that infect corals worldwide. we isolated cyanobacteria from bbd into culture, confirmed their presence in the bbd community by using denaturing gradient gel electrophoresis (dgge), and demonstrated their ecological significance in terms of physiological sulfide tolerance and photosynthesis-versus-irradiance values. twenty-nine bbd samples were collected from nine host coral species, four ... | 2007 | 17601818 |
| the presence of the cyanobacterial toxin microcystin in black band disease of corals. | black band disease (bbd) is a migrating, cyanobacterial dominated, sulfide-rich microbial mat that moves across coral colonies lysing coral tissue. while it is known that bbd sulfate-reducing bacteria contribute to bbd pathogenicity by production of sulfide, additional mechanisms of toxicity may be involved. using hplc/ms, the cyanotoxin microcystin was detected in 22 field samples of bbd collected from five coral species on nine reefs of the wider caribbean (florida keys and bahamas). two cyano ... | 2007 | 17506829 |
