This study aimed to compare the clinical presentations of Aeromonas hydrophila, A. veronii biovar sobria and A. caviae monomicrobial bacteremia by a retrospective method at three hospitals in Taiwan during an 8-yr period. There were 87 patients with A. hydrophila bacteremia, 45 with A. veronii biovar sobria bacteremia and 22 with A. caviae bacteremia. Compared with A. hydrophila and A. veronii ...

Two Aeromonas hydrophila bacteriophages, Aeh1 and Aeh2, were isolated from sewage. Both phages showed binal symmetry. The dimensions of A. hydrophila phages Aeh1 and Aeh2 differed from those of the other Aeromonas phages. Also, phage Aeh2 was the largest Aeromonas phage studied to date. Phage Aeh1 formed small, clear plaques, and phage Aeh2 formed turbid plaques with clear centers. Both phages ...

Key words: Aeromonas hydrophila; cytotoxin; haemo-cytes and fragmented red blood cells, pointing to the lytic–uraemic syndrome presence of microangiopathic anaemia.

Strains of Aeromonas hydrophila isolated from skin infections of common freshwater fish in Bangladesh were tested for enterotoxin production, hemolysin production, and any correlation between these two activities. We also tested the resistance patterns of A. hydrophila to different drugs, especially in relation to ampicillin. The A. hydrophila strains produced an enterotoxin that was related to...

Mesophilic Aeromonas strains express a polar flagellum in all culture conditions, and certain strains produce lateral flagella on semisolid media or on surfaces. Although Aeromonas lateral flagella have been described as a colonization factor, little is known about their organization and expression. Here we characterized the complete lateral flagellar gene cluster of Aeromonas hydrophila AH-3 c...

Aeromonas hydrophila, a zoonotic bacterium found in an expansive range of aquatic ecosystems, has been reported to cause severe diseases in fish, amphibians, reptiles, and mammals, including humans. Herein, we report the draft genome of the hypervirulent A. hydrophila strain HZAUAH isolated from a crucian in China.

Aeromonas hydrophila is an emerging pathogen of poikilothermic animals, from fish to mammals, including humans. Here, we report the whole-genome sequence of the A. hydrophila AH-3 strain, isolated from a fish farm goldfish septicemia outbreak in Spain, with a characterized polar and lateral flagellum glycosylation pattern.

Aeromonas hydrophila is the most common Aeromonas species causing infections in human and other animals such as amphibians, reptiles, fish and crustaceans. Pathogenesis of Aeromonas species have been reported to be associated with virulence factors such as lipopolysaccharides (LPS), bacterial toxins, bacterial secretion systems, flagella, and other surface molecules. Several mutant strains of A...

This study aimed to evaluate phagocytic and bactericidal activity of macrophages originated from murine J774 macrophage cell line against 26 strains of Aeromonas caviae, Aeromonas veronii biotype sobria and Aeromonas hydrophila isolated from human fecal specimens. The analysis of phagocytic index (PI) indicated these strains were phagocytosed in low numbers, below 1.1 x l0(-3) for 65% strains o...

The efficacy of eight routine enteric agars for supporting the growth of 32 strains of Aeromonas spp. (17 A. hydrophila strains, 8 A. sobria strains, and 7 A. caviae strains) was investigated. The plating efficiency of Aeromonas spp. on these media varied greatly (range, 0 to 100%), as did their colony size when compared with that on noninhibitory medium (5% sheep blood agar). Plating efficienc...
