“…Another important phenomenon is that of protists as symbionts. Volkova and Kudryavtsev (2017) detected Perkinsela-related kinetoplastids living as symbionts in deepsea isolates of Neoparamoeba longipodia Volkova and Kudryavtsev, 2017 from about 5000 m depth. Symbioses between bacteria and protists have also been reported, for example, in the case of euglenozoans, allowing their survival under anaerobic conditions (e.g., Yubuki et al 2009).…”

The dark ocean and the underlying deep seafloor together represent the largest environment on this planet, comprising about 80% of the oceanic volume and covering more than twothirds of the Earth's surface, as well as hosting a major part of the total biosphere. Emerging evidence suggests that these vast pelagic and benthic habitats play a major role in ocean biogeochemistry and represent an "untapped reservoir" of high genetic and metabolic microbial diversity. Due to its huge volume, the water column of the dark ocean is the largest reservoir of organic carbon in the biosphere and likely plays a major role in the global carbon budget. The dark ocean and the seafloor beneath it are also home to a largely enigmatic food web comprising little-known and sometimes spectacular organisms, mainly prokaryotes and protists. This review considers the globally important role of pelagic and benthic protists across all protistan size classes in the deep-sea realm, with a focus on their taxonomy, diversity, and physiological properties, including their role in deep microbial food webs. We argue that, given the important contribution that protists must make to deep-sea biodiversity and ecosystem processes, they should not be overlooked in biological studies of the deep ocean.

“…Neoparamoeba perurans is also referred to as Paramoeba perurans (Young et al 2008; Nowak & Archibald, 2018). It has been suggested that Paramoeba and Neoparamoeba should be merged into a single genus prioritising the name Paramoeba (Feehan et al 2013), but this has not been commonly accepted because taxonomic conclusions were based on single‐gene trees with low number of Paramoebidae (Young et al 2014; Volkova & Kudryavtsev, 2017). Other amoeba, including P. branchiphila , P. pemaquidensis / N. pemaquidensis and Nolandella spp., have been observed from gills of fish with AGD using culture and PCR techniques.…”

Gill disease of farmed Atlantic salmon (Salmo salar) in the marine environment has emerged as a significant problem for the salmon aquaculture industry. Different types of marine salmon gill disease reported include amoebic gill disease (AGD), parasitic gill disease, viral gill disease, bacterial gill disease, zooplankton (cnidarian nematocyst)‐associated gill disease, harmful algal gill disease and chemical/toxin‐associated gill disease. The term ‘multifactorial gill disease’ is used when multiple distinguishable types of disease (as opposed to an obvious single primary type) are present. When gill disease is non‐specific, it is referred to as ‘complex gill disease’ (CGD) or ‘complex gill disorder’. These two terms are often used interchangeably and are overlapping. The significance of many infectious and non‐infectious agents that may be associated with CGD is often unclear. In this review, we summarise aspects of the different types of gill disease that are relevant to the epidemiology of gill disease and of CGD in particular. We also tabulate simultaneously occurring putative pathogens to explore the multifactorial nature of gill disease.

“…Although recent molecular evidence suggests that the genera Neoparamoeba and Paramoeba are paraphyletic and could be synonymized [64]; however, doing so would be premature, as nuclear SSU rDNA is highly conserved and insufficient by itself to formalize such a change [65,66]. Therefore, until more scaled amoebae are sequenced and genes other than SSU rDNA are investigated, evidence is insufficient to change the currently used nomenclature [67][68][69].…”

Gill diseases are a growing health challenge in salmon farming worldwide, but many gaps remain in our knowledge. Gill diseases are generally complex and multifactorial disorders, often with presumable spatial and temporal distribution patterns, but are highly difficult to effectively prevent and control. The term complex gill disease (CGD) includes a wide range of clinical disease presentations on the gills of farmed salmon; usually, CGD presents from the end of summer to early winter. The pathogens involved include Neoparamoeba perurans, Tenacibaculum maritimum, Candidatus Piscichlamydia salmonis, Candidatus Branchiomonas cysticola, Desmozoon lepeophtherii (syn. Paranucleospora theridion) and viruses, such as the Atlantic salmon paramyxovirus (ASPV) and salmon gill poxvirus (SGPV). Amoebic gill disease (AGD) is perhaps the most significant disease in terms of gill health and economic impact. AGD results in high mortality, reduced production performance and impaired fish welfare. This review summarizes and analyses CGD research, outbreaks and treatment, with a focus on AGD, as well as on knowledge gaps and avenues for future research.
