Figure 1. Bacterial density on corals sampled from the field:

A. Mean CFU's ml⁻¹ g⁻¹ from crushed Pachyseris speciosa fragments sampled in Nikko Bay Palau. B. Mean CFU's ml⁻¹ g⁻¹ from crushed Montipora aequituberculata fragments sampled in Nelly Bay GBR C. Mean CFU's ml⁻¹ g⁻¹ from crushed Acropora cytheria fragments sampled in Majuro Atoll the Marshall Islands. ▪–Bacterial isolates streaked on TBCS agar. □-Bacterial isolates streaked on MA. Control–samples from coral fragments lacking disease signs. Healthy–Coral tissue lacking disease signs sampled from fragments displaying signs of disease. Interface–Coral tissue sampled at the border between exposed skeleton and healthy tissue. Skeleton–Exposed skeleton in areas of tissue lesions. CFU's ml⁻¹ g⁻¹ are presented in a logarithmic scale. Bars = Standard Errors.
