Vibrio populations in the seawater supply and the water of seven exhibition aquaria that simulate various Mediterranean and tropical ecosystems were compared. The similarity of Vibrio populations in the intestine of various fish species, feed and water was examined. Resistance to the antibiotics used in fish health management was analysed for the dominant Vibrio isolates.
Samples were collected for 1 year from seven exhibition tanks reproducing different ecosystems. The diversity and population similarity among vibrios were determined using a miniaturized biochemical phenotyping method. Similar Vibrio populations were found in the water supply and in the water of the Mediterranean ecosystems. However, different Vibrio populations were found in the water of tanks with tropical ecosystems. Vibrio populations in the water seemed to have a greater effect on the composition of intestinal Vibrio populations than those in feed. No resistance to antibiotics was observed, indicating their appropriate use for health management.
Water characteristics have a greater impact on the composition of Vibrio populations in aquaria and fish intestinal microbiota than bacteria in feed.
The microbiological monitoring water could provide valuable information for managing the health of exhibition aquaria.
比较海水供应中的弧菌种群和七个模拟各种地中海和热带生态系统的展览水族箱中的水的弧菌种群。检查各种鱼类肠道、饲料和水中的弧菌种群的相似性。分析用于鱼类健康管理的抗生素对优势弧菌分离株的抗性。
从七个再现不同生态系统的展览水箱中收集样本，为期一年。使用微型生化表型方法确定弧菌的多样性和种群相似性。在海水供应中和地中海生态系统的水中发现了相似的弧菌种群。然而，在具有热带生态系统的水箱中发现了不同的弧菌种群。水中的弧菌种群似乎对肠道弧菌种群的组成有更大的影响，而不是饲料中的细菌。未观察到抗生素耐药性，表明它们在健康管理中得到了适当的应用。
水的特性对水族箱和鱼类肠道微生物群中弧菌种群的组成有比饲料中的细菌更大的影响。
微生物监测水可以为管理展览水族箱的健康提供有价值的信息。
