Starch-ampicillin agar was used to quantitatively isolate Aeromonas sp. from retail grocery store produce. All produce sampled, including parsley, spinach, celery, alfalfa sprouts, broccoli, and lettuce, contained Aeromonas sp. In most instances, the count of Aeromonas sp. increased 10- to 1,000-fold during 2 weeks of storage at 5 degrees C. Eleven (92%) of 12 kinds of produce yielded cytotoxic...

A eromonas species are Gram-negative, oxidasepositive rods in the family Aeromonadaceae. These organisms have been isolated from untreated drinking water and different types of foods particularly seafood and frozen chicken. Aeromonas species are recognized as agents of serious infections in immunocompromised individuals including septicemia in patients with hepatic cirrhosis with a rapidly fata...

Twenty clinical strains each of Aeromonas hydrophila, Aeromonas caviae, and Aeromonas sobria were evaluated for their abilities to oxidize one or more of 95 carbon sources on a GN Microplate (BIOLOG, Hayward, Calif.). Nine substrates yielded good, discriminatory values for the three species tested. The panel appears to be useful for the species identification of Aeromonas isolates originating f...

The detection of Virulence factors of Aeromonas spp. is a key component in determining potential pathogenicity because these factors act Multifuntionally and Multifactorially. In this study, totally 50 carp fish samples were collected, Among these, 8 samples were found to be positive for Aeromonas hydrophila and 13 were found to be positive for Aeromonas salmonicida. Antibiotic resistant patter...

INTRODUCTION The number of reports of intestinal infections caused by Aeromonas spp. has increased significantly in recent years. In most clinical laboratories, identification of these bacteria is carried out by general phenotypic tests that sometimes do not accurately differentiate Aeromonas and Vibrio. METHODS A duplex-polymerase chain reaction (PCR) was developed directed to 2 targets iden...

Aeromonas infection in humans is associated with certain underlying diseases, especially chronic liver disease or malignancy. However, Aeromonas infection associated with iron overload is rarely reported. We report a case of a 47-year-old female with end-stage renal disease on haemodialysis and on deferoxamine treatment for iron overload who developed Aeromonas sepsis with septic embolism and r...

Aeromonas genus is considered an emerging pathogen and its presence in drinking water supplies is a reason to public health concern. This study investigated the occurrence of Aeromonas in samples from collective reservoirs and wells used as drinking water sources in a peri-urban area. A total of 35 water samples were collected from collective reservoirs and 32 from wells bimonthly, from Septemb...

The phylogenetic relationships of all known species of the genus Aeromonas, and especially Aeromonas bestiarum and Aeromonas salmonicida, were investigated on 70 strains using the rpoD sequence, which encodes the sigma70 factor. This analysis was complemented with the sequence of gyrB, which has already proven useful for determining the phylogenetic relationships in the genus. Nucleotide sequen...

The phenotypic characteristics of 89 Aeromonas strains, most of which had been isolated from feces, were examined. Eighty-two percent of the isolates could be placed into one of four groups on the basis of five tests. The relationship of these groups to the three motile species of Aeromonas (Aeromonas caviae, A. hydrophila, and A. sobria) that have been isolated from humans is unclear. Because ...

five common tetracycline resistance genes tet(a), tet(b), tet(m), tet(o) and tet(s) were studied by polymerase chain reaction in 100 bacteria isolated from iranian fish farms. in the antibiogram test most of the bacteria were either intermediately or completely resistant to tetracycline. nine isolates out of 46 aeromonas spp. contained either tet(a/m/s) resistant genes as follows: tet(a) in a. ...
