珊瑚微生物群因其在宿主抵御致命疾病方面的潜在作用而受到越来越多的关注。然而，珊瑚相关细菌对温度依赖的条件致病菌珊瑚弧菌的作用知之甚少。在这项研究中，我们测试了与造礁珊瑚银河藻相关的细菌是否可以抑制V的生长。珊瑚属。从一个健康的G菌落中成功地分离到29个可培养细菌。花束养在水族馆里。在分离的细菌中，有3株为Ruegeriasp.菌株对V的生长有抑制作用。Coralliilyticus P1作为参比菌株，Vibriosp.在这项研究中被孤立。从其他G菌株中也检出了菌株。通过16S rRNA扩增序列测定，表明该水族馆和以前的野外研究中发现了束状菌落，表明Ruegeriasp.菌株在G。丛生菌落。这些结果说明了Ruegeriasp的潜在作用。保护珊瑚免受致病弧菌的侵袭。
The coral microbiome has attracted increased attention because of its potential roles in host protection against deadly diseases. However, little is known about the role of coral-associated bacteria against the temperature-dependent opportunistic pathogenVibrio coralliilyticus. In this study, we tested whether bacteria associated with the reef-building coralGalaxea fasciculariscould inhibit the growth ofV. coralliilyticus. Twenty-nine cultivable bacteria were successfully isolated from a healthy colony ofG. fasciculariskept in an aquarium. Among the bacterial isolates, threeRuegeriasp. strains inhibited the growth ofV. coralliilyticusP1 as a reference strain andVibriosp. isolated in this study.Ruegeriasp. strains were also detected from otherG. fasciculariscolonies in the aquarium and in previous field studies by 16S rRNA amplicon sequencing, suggesting thatRuegeriasp. strains are common amongG. fasciculariscolonies. These results illuminate the potential role ofRuegeriasp. in protecting corals against pathogenicVibriospecies.
