A VIM metallo-beta-lactamase-producing Aeromonas hydrophila strain carrying an integron-borne bla(VIM-4) gene was isolated from a cirrhotic patient's fecal sample in a Budapest hospital. The variable region of this integron is identical with that of a previously characterized integron from Pseudomonas aeruginosa clinical isolates in Pécs in southern Hungary.

BACKGROUND Aeromonas species are gram-negative rods usually isolated from the gastrointestinal tract. They have been occasionally reported as a cause of extra-intestinal infections such as cellulitis, cholangitis, necrotizing fascitis, meningitis, bacteremia, or peritonitis in both immunocompetent and immunocompromised patients. AIM To determine the role and possible pathogenesis of Aeromonas...

Pseudomonas mosselii Gil3 was isolated from a catfish that survived from lethal challenge with hypervirulent Aeromonas hydrophila (vAh). When assayed in vitro, the bacterium showed antagonism against vAh. Sequence analysis revealed that the genome of P. mosselii Gil3 encodes numerous aromatic metabolism pathways and proteins for biosynthesis of antimicrobial compounds.

We have investigated the usefulness of ribotyping for the differentiation of aeromonads isolated from five patients with gastroenteritis and from the source water, treatment plant, and distribution system of a small public water supply. Aeromonas hydrophila and Aeromonas caviae were isolated from fecal specimens preserved in Cary-Blair transport medium by using blood ampicillin agar or alkaline...

PURPOSE To report a case of endogenous endophthalmitis due to Aeromonas hydrophila in a patient with distal common bile duct carcinoma and biliary sepsis. METHODS A 72-year-old woman with distal common bile duct carcinoma, obstructive jaundice, diabetes mellitus, and hypertension had a 1-day history of blurred vision, redness, and eye discharges in the right eye. An ophthalmic examination sho...

Aeromonas hydrophila sepsis and pneumonia are rare diseases in children that carry a high mortality rate. We report a case of fatal bacteremic pneumonia caused by A. hydrophila in a previously healthy 5-year-old child. The source of infection was not determined and the child died within 4 hours of admission. In children who develop a fulminant disease of pneumonia with or without sepsis, partic...

From October 1995 to February 1997, 13 isolates of Aeromonas species were recovered from four patients treated at National Taiwan University Hospital (Taipei). One of the patients, a diabetic, had simultaneous Aeromonas veronii biotype veronii bacteremia and A. veronii biotype sobria urinary tract infection. Seven weeks after the episode, the patient had necrotizing fasciitis due to A. veronii ...

A total of 319 strains of Aeromonas hydrophila were isolated from 536 fish and 278 prawns for a 2-year period. All the strains were tested for resistance to 15 antibiotics and 100% of the strains was resistant to methicillin and rifampicin followed by bacitracin and novobiocin (99%). Only 3% of the strains exhibited resistance against chloramphenicol. The multiple antibiotic resistance (MAR) in...

The Aeromonas hydrophila type III secretion system (T3SS) has been shown to play a crucial role in this pathogen's interactions with its host. We previously described the genetic organization of the T3SS cluster and the existence of at least one effector, called AexT, in A. hydrophila strain AH-3. In this study, we analyzed the expression of the T3SS regulon by analyzing the activity of the aop...

Gastrointestinal infections of Aeromonas species are generally considered waterborne; for this reason, Aeromonas hydrophila has been placed on the United States Environmental Protection Agency Contaminant Candidate List of emerging pathogens in drinking water. In this study, we compared pulsed-field gel electrophoresis patterns of Aeromonas isolates from stool specimens of patients with diarrhe...
