FIG. 4.
Effect of thymidine supplementation on intracellular replication (A) and cytopathogenicity (B) of GK11 in U937 macrophage-like cells in the presence or absence of thymidine. Experiments were performed in triplicate and repeated at least three times. The data are from a representative experiment. Error bars represent standard deviation of the mean; some of the error bars are too small to be seen.
