Clinical relevance of the recently described species Aeromonas aquariorum.

چکیده
Twenty-two human extraintestinal isolates (11 from blood) and three isolates recovered from patients with diarrhea were genetically characterized as Aeromonas aquariorum, a novel species known only from ornamental fish. The isolates proved to bear a considerable number of virulence genes, and all were resistant to amoxicillin (amoxicilline), cephalothin (cefalotin), and cefoxitin. Biochemical differentiation from the most relevant clinical species is provided.

Genome sequence of a novel human pathogen, Aeromonas aquariorum.
Aeromonas aquariorum, a recently described species, is associated with a variety of human diseases. We present here the first genome sequence of A. aquariorum strain AAk1, which was isolated as the sole pathogen from the blood of a patient with septicemia and necrotizing fasciitis.
متن کاملAeromonas aquariorum sp. nov., isolated from aquaria of ornamental fish.
During a survey to determine the prevalence of Aeromonas strains in water and skin of imported ornamental fish, 48 strains presumptively identified as Aeromonas were isolated but they could not be identified as members of any previously described Aeromonas species. These strains were subjected to a polyphasic approach including phylogenetic analysis derived from gyrB, rpoD and 16S rRNA gene seq...

متن کاملMolecular Characterization of Clinical Isolates of Aeromonas Species from Malaysia
BACKGROUND Aeromonas species are common inhabitants of aquatic environments giving rise to infections in both fish and humans. Identification of aeromonads to the species level is problematic and complex due to their phenotypic and genotypic heterogeneity. METHODOLOGY/PRINCIPAL FINDINGS Aeromonas hydrophila or Aeromonas sp were genetically re-identified using a combination of previously publi...
متن کاملPhenotypic and genetic diversity of motile aeromonads isolated from diseased fish and fish farms
Samples from the kidney of 100 diseased fish with signs of haemorrhagic septicemia and 50 samples from outlet water of fish farms were taken aseptically and cultured. In the laboratory, 75 colonies of gram-negative bacteria were biochemically diagnosed as motile aeromonads in our Bacteriology Laboratory Unit using API 20E rapid identification system. The genotype identification using specific p...
