Taxonomy ofPseudomonas piscicida(Bein) Buck, Meyers, and Leifson

Abstract

Twenty strains of marine bacteria showing the properties of pigmentation and icthyotoxicity were studied for selected physiological features. A quantitative taxonomic analysis with an electronic computer was performed. Eighteen species of Pseudomonas were included in the computer analysis as reference strains. The marine collection formed a homogeneous cluster, 80% similarity, and showed a 67 to 70% similarity to certain of the Pseudomonas species: P. atlantica, P. geniculata, P. synxantha, and P. taetrolens. The marine strains are treated as a phenon describing the species P. piscicida. The species was characterized by the hypothetical Median Organism concept; P. piscicida 14 corresponded most closely to the Median Organism. Flavobacterium piscicida was isolated from "red tide" waters off the southwest coast of Florida (Bein, 1954). Orange pigmentation and iethyotoxicity, conspicuous attributes, guided subsequent isolations from waters off the west coast of Florida, Biscayne Bay, and aquaria of the

Bioactive Compound Synthetic Capacity and Ecological Significance of Marine Bacterial Genus Pseudoalteromonas

“…The yellow-pigmented species P. piscicida has been described as being able to produce a neuromuscular toxin able to kill a variety of fish and crab species [ 7 , 39 , 72 ], however no recent studies have re-examined or confirmed this property and the toxin compound has never been detected. This may suggest P. piscicida is rarely an opportunistic pathogen.…”

Pseudoalteromonas maricaloris sp. nov., isolated from an Australian sponge, and reclassification of [Pseudoalteromonas aurantia] NCIMB 2033 as Pseudoalteromonas flavipulchra sp. nov.

“…All strains studied exhibit polar flagella, require sodium ions for growth, are positive for oxidase and catalase, are negative for denitrification, arginine dihydrolase activity and production of agarase and chitinase, do not produce lipase, produce amylase and gelatinase, grow at 10, 28 and 30 mC and 1, 3, 6 and 10 % NaCl, utilize -glucose, -mannose and fructose, are susceptible to kanamycin, erythromycin, gentamicin and oleandomycin and are not susceptible to benzylpenicillin, oxacillin, lincomycin or O\129. Data were taken from this study and from Gauthier & Breittmayer (1992), Hansen et al (1965), Ivanova et al (1998) and Venkateswaran & Dohmoto (2000). , No data available.…”

Pseudoalteromonas piscicida X-8 causes bleaching disease in farmed Saccharina japonica

“…One of the general characteristics is that most of the strains own yellow pigments (Bowman, 2007). Some strains of P. piscicida species have been proven as the pathogenic bacteria for marine organisms (Bein, 1954;Hansen et al, 1965;Meyers et al, 1959). F. piscicida (synonymous of Pseudoalteromonas piscicida) was capable of killing fishes under laboratory conditions (Bein, 1954).…”
