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% () to 90% ( and ). Topical antibiotic application is a viable and effective tool for halting disease lesions on corals affected by SCTLD.
自2014年以来，石珊瑚组织损失病（SCTLD）已导致佛罗里达礁区大多数硬珊瑚物种大量死亡。在用添加了抗生素的水成功治疗实验室珊瑚上的SCTLD病变后，开发了两种外用糊剂作为直接对野生珊瑚应用抗生素治疗的载体。这些糊剂作为安慰剂进行了测试，并在多种珊瑚物种的活动性SCTLD病变上添加了阿莫西林进行测试。不含抗生素的糊剂（安慰剂治疗）的有效率分别为4%和9%，与未治疗的对照组无差异。在两种糊剂中添加阿莫西林后，有效率显著提高到70%和84%。这种方法在五种不同的珊瑚物种中都显示出有效性，更有效的糊剂的成功率在67%（）到90%（和）之间。局部应用抗生素是阻止受SCTLD影响的珊瑚上疾病病变的一种可行且有效的工具。
