EPO is vital for Mp killing mechanisms <i>in vitro</i> and <i>in vivo</i>.

<p><b>A</b>) Purified human EPO (0.5 µM) was added to Mp (5×10⁶) and viability was assessed over the course of 1 hr. **p<.01,*p<.05. n = 3 experiments. <b>B</b>) Mice were treated with Ova and Mp (O+Mp) as previously described but 2 hrs prior to Mp infection, some mice were given either vehicle (V) or resorcinol (R). Mice were given boosters after 24 hrs and samples harvested at 72 hrs for Mp burden. *p<.05. n = 2 experiments (8–10 mice/group).
