A quantitative study of serum immunoglobulin levels and haemagglutination titres has shown that an injection of the microsporidan Glugea stephani caused a decrease in the humoral response of the winter flounder. These examples demonstrate the effect of temperature on the decrease in total IgM levels and haemagglutination titres in winter flounder simultaneously injected with either G. stephani or horse red blood cells. Transfer of serum from fish injected with spores 3 weeks earlier may also implicate soluble serum factors, such as prostaglandins or leukotrienes, causing the observed decrease in serum IgM levels.
