Disease relevance of Plesiomonas

• A new restriction endonuclease (ENase), PshAI, has been isolated from Plesiomonas shigelloides 319-73, an organism that causes food poisoning in humans [1].
• Alkaline peptone water and XDCA are useful for recovery of Aeromonas but not Plesiomonas, whereas BBG is satisfactory for both organisms [2].
• Shigella sonnei and Hafnia alvei had an identical pattern, likewise Plesiomonas shigelloides, halophilic vibrios and Pseudomonas aeruginosa [3].
• Apart from this, Plesiomonas shigelloides was isolated from several slaughtered pigs and from one slaughterhouse rat; salmonellae were isolated from some slaughtered pigs, and a common finding was H2S-positive E. coli [4].

High impact information on Plesiomonas

• Core oligosaccharides of Plesiomonas shigelloides O54:H2 (strain CNCTC 113/92): structural and serological analysis of the lipopolysaccharide core region, the O-antigen biological repeating unit, and the linkage between them [5].
• New UDP-GlcNAc C4 epimerase involved in the biosynthesis of 2-acetamino-2-deoxy-L-altruronic acid in the O-antigen repeating units of Plesiomonas shigelloides O17 [6].
• Plesiomonas strains were naturally resistant and intermediate to streptomycin, erythromycin and rifampicin [7].
• A degradative bacterium, M6, was isolated and presumptively identified as Plesiomonas sp. strain M6 was able to hydrolyze methyl parathion to p-nitrophenol [8].
• The cellular fatty acid compositions of all the Plesiomonas strains were identical and characterized by the presence of hexadecanoate (16:0) (33%), hexadecenoate (16:1) (28%), octadecenoate (18:1) (9%), and octadecanoate (18:0) (6%) [9].

Chemical compound and disease context of Plesiomonas

• For Plesiomonas sp., alkaline peptone-water and inositol-brilliant green-bile salts agar were optimal [10].
• Structural studies of the O-specific polysaccharide from Plesiomonas shigelloides strain CNCTC 113/92 [11].
• 31P-NMR and 13C-NMR studies of mannose metabolism in Plesiomonas shigelloides. Toxic effect of mannose on growth [12].
• Plesiomonas shigelloides was shown to transport mannose by a phosphoenolpyruvate-dependent phosphotransferase system producing mannose 6-phosphate [12].
• Especially Plesiomonas shigelloides would have an important role within histidine decarboxylating bacteria because it was the sole histamine former isolated that has frequently been associated with the marine aquatic environment [13].

Biological context of Plesiomonas

• Twenty-five strains of Plesiomonas shigelloides isolated from aquatic environment, 10 strains from human cases of diarrhoea and five strains from animals were identified by the polymerase chain reaction technique based on 23S rRNA gene [14].

Gene context of Plesiomonas

• Restriction endonuclease PshAI from Plesiomonas shigelloides with the novel recognition site 5'-GACNN/NNGTC [1].
• Thirty-four O and 19 H sera were used to test 169 strains of Plesiomonas shigelloides from several countries of three continents [15].
• The methanolic extract of B. micrantha (Bark) demonstrated weak inhibitory activities against S. flexneri and S. plesiomonas [16].
