A novel lux operon in the cryptically bioluminescent fish pathogen Vibrio salmonicida is associated with virulence.
The cold-water-fish pathogen Vibrio salmonicida expresses a functional bacterial luciferase but produces insufficient levels of its aliphatic-aldehyde substrate to be detectably luminous in culture. Our goals were to (i) better explain this cryptic bioluminescence phenotype through molecular characterization of the lux operon and (ii) test whether the bioluminescence gene cluster is associated ...
متن کاملSurvival of the fish pathogen Aeromonas salmonicida in seawater.
Survival of Aeromonas salmonicida in natural (non-sterile) seawater, as determined from colony counts on marine agar, was found to be influenced by the presence of potentially inhibitory organisms, i.e., Acinetobacter, Aeromonas hydrophila, Chromobacterium, Escherichia coli, Flavobacterium and Pseudomonas, and their metabolites. Yet, samples, thought to be devoid of culturable A. salmonicida, w...
متن کاملDevelopment of a gene transfer system for curing of plasmids in the marine fish pathogen Vibrio salmonicida.
All reported natural isolates of the marine fish pathogen Vibrio salmonicida contain plasmids, and in another marine fish pathogen, Vibrio anguillarum, it has been shown that a plasmid is important for expression of virulence by the organism. To study the function of the plasmids in V. salmonicida, we developed a gene transfer system based on the plasmid RSF1010 replicon. The gene transfer syst...
متن کاملIn vitro susceptibility of the fish pathogen Aeromonas salmonicida to flumequine.
The activity of the fluoroquinolone flumequine was investigated against the fish pathogen Aeromonas salmonicida and was compared with that of oxolinic acid. Flumequine was more active than oxolinic acid in terms of its MIC against oxolinic acid-resistant isolates of A. salmonicida and was as active as oxolinic acid against susceptible isolates. In contrast to oxolinic acid, flumequine was bacte...
متن کاملIn vitro activities of 4-quinolones against the fish pathogen Aeromonas salmonicida.
The activities of five fluorinated 4-quinolones, namely, sarafloxacin, enrofloxacin, PD127391, PD117596, and CI934, against the fish pathogen Aeromonas salmonicida were investigated and compared with that of oxolinic acid. The results indicated that with the exception of CI934, these drugs are more active than oxolinic acid in terms of MIC. No inoculum effect was observed, but the drugs were le...
