FIG. 7.

Recovery of larvae from parasite-infected air pouches in nontransgenic and Tg5C2 IL-5 transgenic mice represented in Fig. 5. Most larvae migrate out of air pouches in nontransgenic mice within 2 h of infection, whereas the majority of larvae injected into air pouches in transgenic mice are retained for at least 32 h. Each bar represents the mean percentage of larvae recovered relative to the estimated original inoculum ± SEM for two to six mice per group. ∗, significantly different from nontransgenic mice at the same stage of infection; P ≤ 0.01.
