The occurrence of Aeromonas spp. within biofilms formed on stainless steel (SS), unplasticized polyvinyl chloride (uPVC) and glass (GL) substrata was investigated in modified Robbins Devices (MRD) in potable (MRD-p) and recycled (MRD-r) water systems, a Biofilm Reactor (BR) and a laboratory-scale pipe loop (PL) receiving simulated recycled wastewater. No aeromonads were isolated from the MRD-p ...

Aeromonas hydrophila has been infrequently reported as a cause of infection in humans. It has been associated with a variety of clinical syndromes but Aeromonas-related endocarditis is extremely rare. We present the case of a 76year-old diabetic patient who was admitted to our hospital due to severe lumbar pain resistant to nonsteroidal anti-inflammatory drugs accompanied by fever (up to 38.5°C...

the intensive use of antimicrobial agents worldwide for prophylactic and therapeutic purposes has been associated with increase of bacterial resistance in the exposed microbial environment. oxytetracycline is the most frequently used antibacterial in the cold water fish industry because of its broad spectrum of activity and low cost. aeromonas hydrophila and other motile aeromonads are among th...

We report a case of necrotizing fasciitis with probable in vivo transfer of a TEM-24 plasmid-borne extended-spectrum -lactamase (ESBL) gene from Enterobacter aerogenes to Aeromonas hydrophila. The patient was an 87-year-old female with a leg lesion following a trauma. She had a history of rheumatoid polyarthritis treated by 10 mg of prednisone per day, refractory anemia, and chronic venous insu...

The biochemical mechanisms that marine sponges have developed as a chemical defense to protect themselves against micro and subsequent macrobiofouling process might comprise a potential alternative for the preventing attack of biofilm forming bacteria. The present study investigated the antimicrobial activity of a series of major secondary metabolites isolated from the sponges Fasciospongia cav...

An easier assessment model would be helpful for high-throughput screening of Aeromonas virulence. The previous study indicated the potential of Tetrahymena as a permissive model to examine virulence of Aeromonas hydrophila. Here our aim was to assess virulence of Aeromonas spp. using two model hosts, a zebrafish assay and Tetrahymena-Aeromonas co-culture, and to examine whether data from the Te...

The growth of uninjured and heat-injured Aeromonas hydrophila incubated at 5 degrees C (22 days) and 30 degrees C (31 h) under air, N2, and CO2 was investigated. At 30 degrees C, the growth patterns of cells on brain heart infusion agar incubated under air and N2 were similar, although slight differences in the lengths of the lag phases and the final populations were detected. The lag phases of...
