Distribution of Aeromonas species in the intestinal tracts of river fish

Article Abstract:

Aeromonas (A.) species exist in abundance in fish intestines, water, and river sediments, which indicates that this bacterium is indigenous to these habitats. DNA-DNA microplate hybridization identifies the species as A. veronii, A. caviae, A. hydrophila, A. sobria, A. jandaei or others. Though the population density of all these species is much more in carp intestine than in other habitats, Aeromonas has the potential to dominate the microbial community in all the habitats mentioned.

Phenotypic, antigenic, and molecular characterization of Pasteurella piscicida strains isolated from fish

Article Abstract:

Pasteurella piscida is the causative agent of pasteurellosis in fish. Phenotypic, antigenic and molecular characterizations were carried out on P. piscida strains representing European, Japanese and American species. The results showed that the geographically separated strains constitute a single taxon based on all criteria analyzed. These results have implications in the development of vaccines as well as DNA hybridization probes for P. piscida.

Application of ozone disinfection to remove Enterococcus seriolicida, Pasteurella piscicida and Vibro anguillarium from seawater

Article Abstract:

The relationbetween doses of total residual oxidant and the contact time required for the inactivation three marine farms-occuring bacterial fish pathogens is discussed.Enterococcus seriolicida, Vibrio anguillarium and Pasteurella piscicida were the pathogens used in the study. These were inoculated into seawater samples which were then treated with ozone. Results indicate the efficient disinfectionby ozone treatment of coastal seawater.
