Over a nine-month period all animals from an established, 3-million gallon, indoor, closed, artificial sea water aquarium system were temporarily relocated to an outdoor system in another state. The indoor system was drained and remained fallow for the nine-month period. Water samples from the source system prior to animal relocation, the temporary outdoor system and the source system following renovation and animal return were collected and submitted for automated ribosomal intergenic spacer analyses (ASIRA) and pyrosequencing analysis. These data illustrate very different but stable aquatic microbial assemblages between sites. Simultaneous surveillance of resident animal adrenal hormone production and measures of granulocyte and monocyte functional capacity provide compelling evidence for the role of the aquarium microbiome in promoting robust immunological responses.1 We believe this further supports our aquatic animal hygiene hypothesis and highlights the need to better understand aquatic system microbial assemblages and how to manipulate them to promote optimal resident animal health.2,3
