Piscirickettsiaceae Infections
The Piscirickettsiaceae are a family of Pseudomonadota. All species are aerobes found in water.George M. Garrity: ''Bergey's Manual of Systematic Bacteriology''. 2. Auflage. Springer, New York, 2005, Volume 2: ''The Proteobacteria, Part B: The Gammaproteobacteria'' The species ''Piscirickettsia salmonis'' is a fish pathogen and causes piscirickettsiosis ''Piscirickettsia salmonis'' is the bacterial causative agent of piscirickettsiosis, an epizootic disease in salmonid fishes. It has a major impact on salmon populations, with a mortality rate of up to 90% in some species. The type strain, LF-8 ... in salmonid fishes.Martin Dworkin, Stanley Falkow, Eugene Rosenberg, Karl-Heinz Schleifer, Erko Stackebrandt: The Prokaryotes, A Handbook of the Biology of Bacteria''.

Cycloclasticus
''Cycloclasticus'' is a genus in the phylum Pseudomonadota (Bacteria). Etymology The name ''Cycloclasticus'' derives from:Greek noun ''kuklos'', circle or ring; New Latin adjective ''clasticus'' -''a'' -''um'' (from Greek adjective ''klastos'' -''ē'' -''on'', broken in pieces), breaking; New Latin masculine gender noun ''cycloclasticus'', ring-breaker. Species The genus contains a single species, namely '' C. pugetii'' ( Dyksterhouse ''et al''. 1995, (Type species of the genus).; New Latin genitive case masculine gender noun ''pugetii'', of Puget, named in honor of Peter Puget, a British naval officer who participated in the Vancouver Expedition and for whom Puget Sound was named.) Other candidate species, e.g., "C. spirillensus," have not been formally recognized. "C. spirillenus" is notable for its spirillum morphology.

Methylophaga
The genus ''Methylophaga'' consists of halophilic methylotrophic members of the ''Gammaproteobacteria'', all of which were isolated from marine or otherwise low water activity environments, such as the surface of marble or hypersaline lakes. The cells are rod-shaped.Garrity, George M. (2005). Bergey's manual of systematic bacteriology, Volume Two: The Proteobacteria, Part B: The Gammaproteobacteria. New York: Springer . and are motile by a single polar flagellum. (with the possible exception of ''M. aminisulfidivorans'' which has been described as being non-motile) When ''Methylophaga'' was defined originally as a genus in 1985, all species known at that time were auxotrophic for vitamin B12, however, many species were found to be non-auxotrophic and so this is no longer a defining characteristic. ''Methylophaga'' spp. are the dominant methylotrophs in the upper layers of the oceans, and have key roles in the biogeochemical cycling of methanol, monomethylamine, dimethylsulfide a ...

Pseudomonadota
Pseudomonadota (synonym Proteobacteria) is a major phylum of Gram-negative bacteria. The renaming of phyla in 2021 remains controversial among microbiologists, many of whom continue to use the earlier names of long standing in the literature. The phylum Proteobacteria includes a wide variety of pathogenic genera, such as ''Escherichia'', '' Salmonella'', ''Vibrio'', ''Yersinia'', ''Legionella'', and many others.Slonczewski JL, Foster JW, Foster E. Microbiology: An Evolving Science 5th Ed. WW Norton & Company; 2020. Others are free-living (nonparasitic) and include many of the bacteria responsible for nitrogen fixation. Carl Woese established this grouping in 1987, calling it informally the "purple bacteria and their relatives". Because of the great diversity of forms found in this group, it was later informally named Proteobacteria, after Proteus, a Greek god of the sea capable of assuming many different shapes (not after the Proteobacteria genus ''Proteus'').
