Hb reduction is the difference between %Hb on day prior to first cycle infection and treatment, and day on which Hbm was observed (blood harvested for serum). The data presented here are pooled results of two separate experiments. aOne-way ANOVA with Tukey's post-test. bSignificantly higher than CBA; Significantly c lower, dhigher than B6, NZW, CBA; eSignificantly higher than B6, NZW. Hbm, minimum Hb.
