Abstract
In the previous paper, the pathogenic organisms isolated from the scale protrusion disease of carp fishes, were identified as Aeromonas liquefaciens according to the morphological, biochemical and biological properties.
In this study, the serological relationship between these isolates and related organisms was investigated. The results obtained are as follows:
1. Aeromonas punctata strain ATCC-11163 and A. liquefaciens strain UT-62 were agglutinated by antisera of the isolated strains CA-1 and CB-1. However, A. hydrophila strain NRRL-B-909 and A. salmonicida were the organisms which failed to react with antisera prepared against strains CA-1 or CB-1.
2. Agglutinin-absorption studies were carried out in order to examine further the antigenic relationship between the isolates and strains ATCC-11163 or UT-62. As the result of experiments, it was confirmed that the isolates, strains ATCC-11163 or UT-62 was not complete antigenical agreement.
