刺胞动物水母是海洋水产养殖的害虫物种，其对养殖鱼类的严重影响有据可查，特别是影响脆弱的鳃组织。人们对接触的后续后果知之甚少，包括其与继发细菌感染的关系。本研究的目的是确定三种水母水母的粘附微生物种群中是否存在潜在致病菌； Obelia geniculata、Neoturris fillata 和狮鬃水母 Cyanea capillata。鉴定出一些商业水产养殖的潜在病原体，包括杀鲑气单胞菌、灿烂弧菌和溶藻弧菌。这些发现表明，水母不仅是水产养殖中鱼类直接创伤的媒介，而且也是细菌性疾病的潜在宿主和传播媒介。由于水母可能在海水养殖的沿海水域中增加，因此水母在细菌爆发中的作用对全球海水养殖具有影响。
Cnidarian jellyfish are pest species of marine aquaculture, with their acute impacts well documented in farmed fish, particularly affecting the delicate gill tissue. Less is known about subsequent consequences of exposure, including their association with secondary bacterial infections. The aim of this study was to identify whether potentially pathogenic bacteria were present as part of the adherent microbial populations of three medusozoan jellyfish species; Obelia geniculata, Neoturris pileata and the Lion's Mane jellyfish Cyanea capillata. A number of potential pathogens of commercial aquaculture were identified, including Aeromonas salmonicida, Vibrio splendidus and Vibrio alginolyticus. These findings suggest that jellyfish must be considered not just agents of direct trauma to fish in aquaculture, but also potential reservoirs and vectors of bacterial disease. Since jellyfish may be increasing in the coastal waters where marine aquaculture occurs, the role of jellyfish in bacterial outbreaks has implications for marine aquaculture globally.
