It is known that Aeromonas spp. possess different chromosomal β-lactamase genes. Presence and phenotypic expression of bla TEM, bla SHV, and bla CTX-M ESBL-encoding genes were investigated in environmental water isolates of Aeromonas hydrophila and Aeromonas jandaei. Presence of bla SHV and bla CTX-M genes was not observed, and bla TEM gene was verified in 91% of the isolates. Sequencing of 10 ...
Background: Aeromonas species are Gram-negative ubiquitous bacteria, facultative anaerobic rods that infect both invertebrates and vertebrates. Various fish species develop hemorrhagic disease and furunculosis due to Aeromonas spp. Aeromonas strains generate certain active compounds such as siderophores, which are the final products of non-ribosomal peptide synthetase (NRPS) activity. The prese...
Aeromonas hydrophila strain KOR1, isolated from mangrove rhizosphere soil, has the ability to produce the quorum-sensing signal molecule. Here, we report the 4.78-Mb genome sequence of strain KOR1, and found its quorum-sensing encoding gene LuxR. The data will be crucial to understanding the quorum-sensing-dependent phenotypes of this bacterium.
The medicinal leech has established a long-term mutualistic association with Aeromonas veronii, a versatile bacterium which can also display free-living waterborne and fish- or human-pathogenic lifestyles. Here, we investigated the role of antibiotics in the dynamics of interaction between the leech and its gut symbiont Aeromonas. By combining biochemical and molecular approaches, we isolated a...
Clinical strains of Aeromonas hvdrophlla and Aeromonas sobria were used to develop a mouse model for determining virulence potentials of food isolates. lntraperitoneal injection with these strains caused hemorrhaging and death of 10—12 week old male BALB/c mice within 24 h post challenge. Nonsupplemented injections of Aeromonas sp. suspensions resulted in a median LD 50 value of 4.9 X 10 cells,...
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...
Rectal swabs from 391 infants less than 18 months of age who were hospitalized with acute diarrhea and from 138 similarly aged healthy infants were examined for the etiologic agents of diarrhea. Aeromonas spp. were recovered from 205 of 391 (52.4%) diarrheic patients, whereas they were recovered from 12 of 138 (8.7%) controls (P less than 10(-11). Among the 205 Aeromonas-positive diarrheic pati...

INTRODUCTION Aeromonas veronii biovar sobria is a rare cause of bacteremia, with several studies indicating that this isolate may be of particular clinical significance since it is enterotoxin producing. A wide spectrum of infections has been associated with Aeromonas species in developing countries that include gastroenteritis, wound infections, septicemia and lung infections. This infection, ...
Conventional identification of Aeromonas species based on biochemical methods is challenged by the heterogeneous nature of the species. Here, we present a new multiplex PCR method directed toward the gyrB and rpoB genes that identifies four Aeromonas species, A. hydrophila, A. media, A. veronii, and A. caviae, and we describe the application of this method on a Danish strain collection.
