Effects of Experimental Sarcocystis neurona-Induced Infection on Immunity in an Equine Model

Figure 5

Individual PMA/I stimulation indices for non-experimentally infected (a) and S. neurona experimentally infected (b) horses. Lymphocyte proliferation assays using the (3H)-thymidine assay were performed with a variety of mitogens, including the pan-leukocyte stimulant, PMA/I. Stimulation indices were calculated by dividing the average counts per minute for cells stimulated with each mitogen, by the counts per minute for spontaneously proliferating cells. Results are reported by individual horse response and the average response of the horses by treatment by day.
