  • Comparative Proteomic Profiling of Newly Acquired, Virulent And
    www.nature.com/scientificreports OPEN Comparative proteomic profling of newly acquired, virulent and attenuated Neoparamoeba perurans proteins associated with amoebic gill disease Kerrie Ní Dhufaigh1*, Eugene Dillon2, Natasha Botwright3, Anita Talbot1, Ian O’Connor1, Eugene MacCarthy1 & Orla Slattery4 The causative agent of amoebic gill disease, Neoparamoeba perurans is reported to lose virulence during prolonged in vitro maintenance. In this study, the impact of prolonged culture on N. perurans virulence and its proteome was investigated. Two isolates, attenuated and virulent, had their virulence assessed in an experimental trial using Atlantic salmon smolts and their bacterial community composition was evaluated by 16S rRNA Illumina MiSeq sequencing. Soluble proteins were isolated from three isolates: a newly acquired, virulent and attenuated N. perurans culture. Proteins were analysed using two-dimensional electrophoresis coupled with liquid chromatography tandem mass spectrometry (LC–MS/MS). The challenge trial using naïve smolts confrmed a loss in virulence in the attenuated N. perurans culture. A greater diversity of bacterial communities was found in the microbiome of the virulent isolate in contrast to a reduction in microbial community richness in the attenuated microbiome. A collated proteome database of N. perurans, Amoebozoa and four bacterial genera resulted in 24 proteins diferentially expressed between the three cultures. The present LC–MS/ MS results indicate protein synthesis, oxidative stress and immunomodulation are upregulated in a newly acquired N. perurans culture and future studies may exploit these protein identifcations for therapeutic purposes in infected farmed fsh. Neoparamoeba perurans is an ectoparasitic protozoan responsible for the hyperplastic gill infection of marine cultured fnfsh referred to as amoebic gill disease (AGD)1.

Nowak School of Aquaculture and Aquafin CRC, University of Tasmania, Locked Bag 1370, Launceston, Tasmania 7250, Australia ABSTRACT: To study the concentration effects of the bacterium Winogradskyella sp. on amoebic gill disease (AGD), Atlantic salmon Salmo salar were pre-exposed to 2 different doses (108 or 1010 cells l–1) of Winogradskyella sp. before being challenged with Neoparamoeba spp. Exposure of fish to Winogradskyella sp. caused a significant increase in the percentage of AGD-affected filaments com- pared with controls challenged with Neoparamoeba only; however, these percentages did not increase significantly with an increase in bacterial concentration. The results show that the presence of Winogradskyella sp. on salmonid gills can increase the severity of AGD.

  • (Salmo Salar) with Amoebic Gill Disease (AGD) Chlo
    The diversity and pathogenicity of amoebae on the gills of Atlantic salmon (Salmo salar) with amoebic gill disease (AGD) Chloe Jessica English BMarSt (Hons I) A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2019 i Abstract Amoebic gill disease (AGD) is an ectoparasitic condition affecting many teleost fish globally, and it is one of the main health issues impacting farmed Atlantic salmon, Salmo salar in Tasmania’s expanding aquaculture industry. To date, Neoparamoeba perurans is considered the only aetiological agent of AGD, based on laboratory trials that confirmed its pathogenicity, and its frequent presence on the gills of farmed Atlantic salmon with branchitis. However, the development of gill disease in salmonid aquaculture is complex and multifactorial and is not always closely associated with the presence and abundance of N. perurans. Moreover, multiple other amoeba species colonise the gills and their role in AGD is unknown. In this study we profiled the Amoebozoa community on the gills of AGD-affected and healthy farmed Atlantic salmon and performed in vivo challenge trials to investigate the possible role these accompanying amoebae play alongside N. perurans in AGD onset and severity. Significantly, it was shown that despite N. perurans being the primary aetiological agent, it is possible AGD has a multi-amoeba aetiology. Specifically, the diversity of amoebae colonising the gills of AGD-affected farmed Atlantic salmon was documented by culturing the gill community in vitro, then identifying amoebae using a combination of morphological and sequence-based taxonomic methods. In addition to N. perurans, 11 other Amoebozoa were isolated from the gills, and were classified within the genera Neoparamoeba, Paramoeba, Vexillifera, Pseudoparamoeba, Vannella and Nolandella.

  • Epidemiology of Amoebic Gill Disease
    Epidemiology of amoebic gill disease By Greetje Marianne Douglas-Helders B.Sc., M.Sc. Submitted in fulfilment of the requirements for the Degree of Doctor of Philosophy University of Tasmania, November 2002 Declaration This thesis contains no material which has been accepted for a degree or diploma by the University or any other institution, except by way of background information and duly acknowledged in the thesis, and to the best of my knowledge and belief no material previously published or written by another person except where due acknowledgments is made in the text of the thesis. Marianne Douglas-Helders Authority of Access This thesis n-lay be made available for loan and limited copying in accordance with the Copyright Act 1968 Marianne Douglas-Helders Abstract Amoebic gill disease (AGD) is the main disease affecting the salmon industry in Australia, however inadequate information is available on the epidemiology of amoebic gill disease (AGD) and the biology of the pathogen, Neoparamoeba pemaquidensis (Page, 1987). Thus far no convenient mass screening test was available. In this project a pathogen specific and non-lethal dot blot test was developed and validated against indirect fluorescence antibody testing (IFAT), the 'gold standard'. The agreement between the 300 paired gill mucus samples that were analysed using both tests was high, with a corrected kappa value of 0.88. The overall aim of this project was to investigate distributions and seasonal patterns of the pathogen, identify risk factors for the disease and reservoirs of N. pemaquidensis, and develop and review husbandry methods in order to reduce AGD prevalence.

  • Role of Bacteria in Amoebic Gill Disease
    Role of bacteria in amoebic gill disease by Sridevi Embar-Gopinath B.Sc., M.Sc., M.Phil.

Sridevi Embar-Gopinath i Abstract 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.
