Aeromonas hydrophila

Department of Biology, University of Alabama a t Birmingham, Birmingham, AL 35294-1 170, USA Aeromonas hydrophila, a gastrointestinal pathogen of humans, was shown to exhibit a significant adaptive acid tolerance response (ATR) capable of protecting cells from severe acid at a pH of 3.5. The ATR was induced by exposure to a relatively mild pH level of 5-0 for 20 min. Adaptation required protein...

Antimicrobial susceptibility of Aeromonas hydrophila.

Minimal inhibitory concentration determinations and disk diffusion and Autobac 1 susceptibility tests were performed on 22 strains of Aeromonas hydrophila. Eleven of the strains had discrepancies between Autobac and disk diffusion or minimal inhibitory concentration results. These discrepancies occurred with the beta-lactam antibiotics, primarily carbenicillin and cephalothin. It is recommended...

Aspartate Transcarbamoylase of Aeromonas Hydrophila

Phloroglucinol derivatives from Aeromonas hydrophila.

greenhouse-grown red pine seedling, Pinus resinosa, when cultured on malt agar or potato dextrose agar (PDA) showed inhibitory activity against selected test fungi. Sensitive fungi included Ceratocystis ulmi (BUISM.) C. MOREAU, Pythium spp., Rhizoctonia solani KUHN, Cylindrocarpon sp., Fusarium oxysporum SCHLECT., and Sirococcus strobilinus PREUSS. When grown on PDA, a colorless crystalline sol...

Aeromonas hydrophila produces conductive nanowires.

Aeromonas hydrophila is a facultative anaerobe which, under conditions of oxygen depletion, uses Fe(III) as electron acceptor. A. hydrophila produces pili during growth with Fe(III). The study was focused on the characterization of the morphology, the electrical properties and the nature of the bacterial pili. Scanning electron microscopy and conductive-probe atomic force microscopy revealed th...
