Abstract

The decline in populations in Colombian reefs has been mainly attributed to diseases outbreaks. The population size structure and prevalence of white pox and white band disease were evaluated in six localities of the Colombian Caribbean. Here, we aimed to isolate enteric bacteria and Vibrios from healthy and diseased coral mucus to relate its presence to the health status of . The isolated bacteria were identified using molecular analyses with the 16S rRNA gene. Larger colonies had the highest percentage of the prevalence of both diseases. The strains that were identified as sp. and sp. were common in the healthy and diseased mucus of the holobiont. The sp. and sp. strains isolated from diseased mucus may indicate maintenance and resilience mechanisms in the coral. sp. and other bacteria of the Enterobacteriaceae family were isolated from some localities, suggesting that probably contamination due to poor treatment of domestic wastewater and contributions from river discharges can affect coral health. The spatial heterogeneity of Colombian coral reefs exhibited variability in the bacteria, wherein environmental alterations can trigger signs of disease.

摘要

哥伦比亚珊瑚礁种群数量的下降主要归因于疾病爆发。对哥伦比亚加勒比地区六个地点的种群大小结构以及白痘病和白带病的患病率进行了评估。在此，我们旨在从健康和患病珊瑚黏液中分离肠道细菌和弧菌，以将其存在情况与珊瑚的健康状况相关联。使用16S rRNA基因的分子分析方法对分离出的细菌进行鉴定。较大的菌落中两种疾病的患病率最高。被鉴定为[具体菌种1]属和[具体菌种2]属的菌株在共生体的健康和患病黏液中都很常见。从患病黏液中分离出的[具体菌种1]属和[具体菌种2]属菌株可能表明珊瑚具有维持和恢复机制。从一些地点分离出了[具体菌种3]属和肠杆菌科的其他细菌，这表明生活污水处理不当以及河流排放的影响可能会影响珊瑚健康。哥伦比亚珊瑚礁的空间异质性在细菌方面表现出变异性，其中环境变化会引发疾病迹象。
