Description

In the previous paper, the morphological, biological and biochemical properties of the organisms isolated from diseased yellowtail, Seriola quinqueradiata, and red sea bream, Chrysophrys major, had been investigated, and the isolates were identified as Staphylococcus epidermidis.<BR>In this study, the serological properties of the organisms isolated from diseased yellowtail, red sea bream and ell, Anguilla japonica, were investigated by cross-agglutination test, cross-absorption test and gel precipitation tequnique. Also the influence of the incubation period and temperature, and heating on agglutination were examined. The results are summarized as follows :<BR>1. The common antigens were recognized among the isolates by agglutination and precipitation techniques. All isolates were found to be polyvalent in antigenic composition.<BR>2. Incubation period and temperature of the isolates didn't influence on the agglutination of the major antigens on the isolates.<BR>3. Some isolates which failed to agglutinate in live condition were observed to agglutinate in antisera after heating.<BR>4. On the basis of the results, the isolates except SHy-1 were divided into 5 serotypes from A to E as follows: type A, 110-1; type B, 110-2; type C, 110-3, 110-4, 110-5, 110-8, M110-1 and SHy-2; type D, 110-6 and 110-7; type E, K110-1.
