抄録

Fecal pellets from 4 goldfish specimens were successively analyzed to obtain the knowledge on the fluctuation of the fecal flora.Aeromonas hydrophila and Bacteroides type A were predominant components in all fish specimens, Enterobacteriaceae and Pseudomonas were also predominant ones in specific individuals, whereas these were detected in 25 to 80% of fecal samples in other individuals. Aeromonas punctata, Flavobacterium, Staphylococcres and Clostridium occurred pre-dominantly in several cases, The remaining components were occasionally isolated at low bacterial densities.<br> It was shown from the above results that each fish individual had a character of fecal flora and that there is a great day-to-day variation of the fecal flora of goldfish.
