本研究探讨了一种新的水泡样综合征在电镀珊瑚Echinopora lamellosa的潜在原因。对这种新型珊瑚综合征的目视检查没有显示出明显的大型寄生虫迹象，水泡本身表现为珊瑚表面上充满液体的囊，这些囊从珊瑚息肉之间的共囊体中升起。水疱的组织学分析显示，表皮或胃真皮组织没有相关坏死。水疱区域和明显健康组织之间的唯一差异是直接在水疱界面（水疱边缘与明显健康组织连接的区域）存在增殖生长（可能的粘膜细胞增生）。在任何组织学样本中均未发现细菌聚集体，也未发现任何组织坏死迹象。我们的结论是，水疱形成不是由特定的微生物感染引起的，而是可能是表皮生长异常后刺激的结果。然而，今后的工作应进行寻找其他潜在的临时代理人，包括病毒。
This study investigates potential causes of a novel blister-like syndrome in the plating coral Echinopora lamellosa. Visual inspections of this novel coral syndrome showed no obvious signs of macroparasites and the blisters themselves manifested as fluid-filled sacs on the surface of the coral, which rose from the coenosarc between the coral polyps. Histological analysis of the blisters showed that there was no associated necrosis with the epidermal or gastrodermal tissues. The only difference between blistered areas and apparently healthy tissues was the presence of proliferated growth (possible mucosal cell hyperplasia) directly at the blister interface (area between where the edge of the blister joined apparently healthy tissue). No bacterial aggregates were identified in any histological samples, nor any sign of tissue necrosis identified. We conclude, that the blister formations are not apparently caused by a specific microbial infection, but instead may be the result of irritation following growth anomalies of the epidermis. However, future work should be conducted to search for other potential casual agents, including viruses.
