Antiparasite treatments reduce humoral immunity and impact oxidative status in raptor nestlings
Abstract: Parasites are natural stressors that may have multiple negative effects on their host as they usurp energy and nutrients and may lead to costly immune responses that may cause oxidative stress. At early stages, animals may be more sensitive to infectious organisms because of their rapid gr...
