Effect of host age on the expression of acquired resistance to ticks

Summary

Young guinea-pigs (350 g) expressed significantly greater levels of acquired resistance to challenge by larvalAmblyomma americanum ticks than older guinea-pigs (520–800 g). This finding suggests that younger guinea-pigs are immunologically more responsive to tick infestation than older mature individuals. Therefore, host age is an important variable in evaluating acquired resistance to ticks.
