In this report, we announce the complete genome sequence of Aeromonas hydrophila strain YL17. Single-molecule real-time (SMRT) DNA sequencing was used to generate the complete genome sequence and the genome-wide DNA methylation profile of this environmental isolate. A total of five unique DNA methyltransferase recognition motifs were reported here.

Aeromonas hydrophila is an opportunistic pathogen and the leading cause of fatal hemorrhagic septicemia in rainbow trout. A gene encoding an elastolytic activity, ahyB, was cloned from Aeromonas hydrophila AG2 into pUC18 and expressed in Escherichia coli and in the nonproteolytic species Aeromonas salmonicida subsp. masoucida. Nucleotide sequence analysis of the ahyB gene revealed an open readi...

The pathogenic bacterium Aeromonas hydrophila has been shown to exclusively utilize a ligand exchange mechanism for siderophore-mediated iron uptake, with a single nonspecifi c siderophore receptor facilitating iron exchange. However, the genes involved in this process, including the gene encoding the nonspecifi c receptor, are unknown. Here we identify and characterize a novel gene, nsr1, from...

In 222 Rana pipiens frogs and 34 tadpoles captured in and near Minnesota, Aeromonas hydrophila and 29 species of Enterobacteriaceae, including yersinia enterocolitica and Salmonella arizonae, were isolated from intestines. The prevalence of members of the family Enterobacteriaceae was lowest in frogs captured in early spring and highest in frogs captured in late summer.

The aim of this study was to isolate β-haemolytic Aeromonas hydrophila strains from live rainbow trouts (Oncorhynchus mykiss) destined for human consumption and to investigate their resistance to antimicrobial drugs. Sterile swab samples were collected from 52 rainbow trouts. Fifteen (28.8%) βhaemolytic Aeromonas strains were isolated from collected 52 swab samples. Through API 20 NE, 12 of the...

Densities of Aeromonas hydrophila showed distinct thermal optima (25 to 35 degrees C) and thermal maxima (45 degrees C) when measured along thermal gradients created by geothermal and nuclear reactor effluents. Survival of A. hydrophila never exceeded 48 h at temperatures of greater than 45 degrees C. Thermophilic strains could not be isolated at any site.

Aeromonas hydrophila is a rare human pathogen. Reports of zoonotic infection developing after large feline bites are even rarer. We are documenting the first case of human wound infection with A. hydrophila following a tiger bite. The patient responded well following wound debridement, secondary suturing and combination antibiotic therapy.

Motile aeromonad septicemia caused by mesophilic strains of Aeromonas hydrophila is a widespread problem in cultured freshwater fish. We announce here the draft genome sequence of the multidrug-resistant A. hydrophila strain Ae25, isolated from a koi carp (Cyprinus carpio) with motile aeromonad septicemia that was collected from an ornamental fish-breeding farm in Sri Lanka.

The genus Aeromonas comprises known virulent and avirulent isolates and has been implicated in waterborne disease. A common infection model of human gastroenteritis associated with A. hydrophila uses neonatal mice. The goal of this research was to evaluate whether a murine small intestinal cell line could provide comparable results to the gene expression changes in the neonatal mouse model. Cha...

Aeromonas hydrophila inhabits freshwater and soil and is mainly pathogenic to cold-blooded animals. It is known to cause red leg disease in frogs, septicemia and stomatitis in snakes and infections in freshwater fish. 1 Human infections due to members of the genus Aeromonas are considered rare and mainly occur in immune compromised individuals or patients who are suffering from chronic disease....
