Thiaminase activity of crucian carp Carassius carassius injected with a bacterial fish pathogen, Aeromonas salmonicida subsp. salmonicida.
Dietary thiaminase I is a cause of thiamine deficiency in animals. The physiological significance of thiaminase in the organisms containing this enzyme is not known, nor are the factors causing variation in their thiaminase activity. Tests were performed to evaluate the effect a pathogen might have on thiaminase activity in fish, when analyzed both with a cosubstrate added (CATA tests) and no c...
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 کاملEpidemiology of Danish Aeromonas salmonicida subsp. salmonicida in Fish Farms Using Whole Genome Sequencing
Furunculosis, a serious infection caused by the bacterium Aeromonas salmonicida subsp. salmonicida is common in sea-reared rainbow trout production in Denmark. Developing an effective control strategy requires knowledge of the epidemiology, as well as the genomic and virulent variability of the Danish A. salmonicida subsp. salmonicida isolates. To obtain this, the genomes of 101 A. salmonicida ...
متن کاملEvidence for a type III secretion system in Aeromonas salmonicida subsp. salmonicida.
Aeromonas salmonicida subsp. salmonicida, the etiological agent of furunculosis, is an important fish pathogen. We have screened this bacterium with a broad-host-range probe directed against yscV, the gene that encodes the archetype of a highly conserved family of inner membrane proteins found in every known type III secretion system. This has led to the identification of seven open reading fra...
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...
