Impacts of gut parasites on the acute phase immune response

Total amount of gut worms vs. fever temperature graphCan gut parasites drive variation in avian inflammatory immune responses?

In mammals, worms that live in the digestive tract can bias their hosts' immune systems away from inflammatory responses. Our data suggest that such processes could help drive differences in immune responses like fever and sickness behaviors (lethargy) in song sparrows. For her MS work Grace Vaziri performed field experiments to determine if this is the case.
