| Summary: | Neoparamoeba spp., are the causative agent of amoebic gill disease (AGD) in marine farmed Atlantic salmon, Salmo salar and AGD is the major problem faced by the salmonid industry in Tasmania. The only effective treatment to control AGD is freshwater bathing; however, complete removal of the parasite is not achieved and under favourable conditions AGD can reoccur within 10 days. Previous research on AGD suggests that gill bacteria might be one of the factors influencing colonisation of Neoparamoeba spp. onto Atlantic salmon gills. Therefore, the aim of this project was to investigate the role of salmonid gill bacteria in AGD. To obtain good understanding of the bacterial populations present on Atlantic salmon gills, bacteria samples were collected twice during this study. Initially, bacteria were cultured from AGD-affected and unaffected fish both from laboratory and farm. These bacteria were characterised based on the colony morphology and biochemical profiles and identified using 16S rRNA gene-based ... |
