Piscirickettsiaceae
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 in salmonid fishes.Martin Dworkin, Stanley Falkow, Eugene Rosenberg, Karl-Heinz Schleifer, Erko Stackebrandt: The Prokaryotes, A Handbook of the Biology of Bacteria''. Volume 5: Proteobacteria: Alpha and Beta Subclasses'' It lives in cells of infected hosts and cannot be cultured on artificial media. ''Piscirickettsia salmonis'' is nonmotile, whereas the other five genera are motile by using a single flagellum A flagellum (; ) is a hairlike appendage that protrudes from certain plant and animal sperm cells, and from a wide range of microorganisms to provide motility. Many protists with flagella are termed as flagellates ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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-89, is from Chile, but multiple strains exist, and some are more virulent than others. ''P. salmonis'' and piscrickettsiosis are present in various geographic regions from Europe to Oceania to South America, but the Chilean salmon farming industry has been particularly hard-hit. Different strategies of controlling the disease and farm-to-farm spread have been the subject of much research, but a significant amount is still unknown. History The disease caused by ''Piscirickettsia salmonis'', piscirickettsiosis, was first identified in Chile in 1989 as coho salmon syndrome, although observations of the illness date to at least 1981. P. salmonis was first described in 1992, when it was identified as the causative agent of the disease and cla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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.
