We performed histological examination of 69 samples of Acropora sp. manifesting different types of tissue loss (Acropora White Syndrome-AWS) from Hawaii, Johnston Atoll and American Samoa between 2002 and 2006. Gross lesions of tissue loss were observed and classified as diffuse acute, diffuse subacute, and focal to multifocal acute to subacute. Corals with acute tissue loss manifested microscopic evidence of necrosis sometimes associated with ciliates, helminths, fungi, algae, sponges, or cyanobacteria whereas those with subacute tissue loss manifested mainly wound repair. Gross lesions of AWS have multiple different changes at the microscopic level some of which involve various microorganisms and metazoa. Elucidating this disease will require, among other things, monitoring lesions over time to determine the pathogenesis of AWS and the potential role of tissue-associated microorganisms in the genesis of tissue loss. Attempts to experimentally induce AWS should include microscopic examination of tissues to ensure that potentially causative microorganisms associated with gross lesion are not overlooked.
我们对 2002 年至 2006 年间来自夏威夷、约翰斯顿环礁和美属萨摩亚的表现出不同类型组织损失（珊瑚白化综合征-AWS）的 69 个 Acropora sp.样本进行了组织学检查。观察到组织损失的大体病变，并将其分类为弥漫性急性、弥漫性亚急性和局灶性至多灶性急性至亚急性。具有急性组织损失的珊瑚表现出有时与纤毛虫、寄生虫、真菌、藻类、海绵或蓝细菌相关的坏死的微观证据，而具有亚急性组织损失的珊瑚主要表现为伤口修复。AWS 的大体病变在微观水平上有多种不同的变化，其中一些涉及各种微生物和后生动物。阐明这种疾病需要，除其他外，随着时间的推移监测病变，以确定 AWS 的发病机制以及组织相关微生物在组织损失发生中的潜在作用。实验诱导 AWS 的尝试应包括组织的显微镜检查，以确保不会忽略与大体病变相关的潜在致病微生物。
