In vitro natural killer cell activity in green turtles (Chelonia mydas) with and without fibropapillomatosis (FP) from Florida’s Big Bend, USA measured as a percentage of specific mortality (mean ± standard error). A ratio of effector cells (i.e., natural killer cells) to target cells (i.e., YAC-1 tumor cell lines) of 50:1 was chosen. (a) Natural killer cell activity was significantly higher in turtles (at p < 0.05) without fibropapilloma (FP) tumors, designated by the asterisk. (b) No statistically significant differences in natural killer cell activity by tumor score were observed.
