Abstract

Accelerated graft rejection can be used to determine immune memory in the gorgonian coral swiftia exserta. The extent ofthe persistence of immune memory will be determined in this experiment using replicate sets that are time elapsed from 1, 3, and 6 month. Although corals lack circulatory systems which can be a component of adaptive systemic immunity, this study will attempt to determine whether this gorgonian coral is capable of transmitting immune information throughout its colonial body. Results showed that at each of the time points; one, three, and six months the secondary response group and the primary response group were significantly different (at p=0.001) therefore, demonstrating long term immune memory. While the primary response group and the 3rd party specificity response group were similar, both were significantly different (at p=O. 001) from the secondary response group which shows the response to be specific, with memory applicable to the original antigen. Systemic immunity was not determined to be present for 15 em and one week after initial sensitization.
