自2014年以来，石珊瑚组织丧失病（SCH12）导致佛罗里达珊瑚礁区的大多数硬珊瑚物种大量死亡。在使用添加抗生素的水成功治疗实验室珊瑚的SCTLD病变后，开发了两种外用糊剂作为直接对野生珊瑚进行抗生素治疗的载体。这些糊剂作为安慰剂进行测试，并添加阿莫西林对多种珊瑚物种的活动性SCREEN损伤进行测试。不含抗生素的糊剂（安慰剂治疗）的有效性为4%和9%，与未治疗的对照组没有差异。在两种糊剂中加入阿莫西林，有效性显著提高至70%和84%。在五种不同的珊瑚物种中观察到这种方法的有效性，更有效的糊剂的成功率从67%（Colpophyllia natans）到90%（Orbicella faveolata和Montastraea cavernosa）不等。局部应用抗生素是一种可行和有效的工具，可以阻止受SCERANS影响的珊瑚的疾病病变。
Since 2014, Stony Coral Tissue Loss Disease (SCTLD) has led to mass mortality of the majority of hard coral species on the Florida Reef Tract. Following the successful treatment of SCTLD lesions on laboratory corals using water dosed with antibiotics, two topical pastes were developed as vehicles to directly apply antibiotic treatments to wild corals. These pastes were tested as placebos and with additions of amoxicillin on active SCTLD lesions on multiple coral species. The effectiveness of the pastes without antibiotics (placebo treatments) was 4% and 9%, no different from untreated controls. Adding amoxicillin to both pastes significantly increased effectiveness to 70% and 84%. Effectiveness with this method was seen across five different coral species, with success rates of the more effective paste ranging from 67% (Colpophyllia natans) to 90% (Orbicella faveolata and Montastraea cavernosa). Topical antibiotic application is a viable and effective tool for halting disease lesions on corals affected by SCTLD.
