Changes have been observed in the biology of protozoan and helminth parasites of small mammals during a variety of experimental nutritional manipulations ranging from deficiency in a specific nutrient to the general withholding of food from the host. Commonly observed effects include retardations in parasite growth rate, gametogenesis, fecundity, and asexual multiplication. The duration of patency and of the association of a parasite with its host have also been observed to be curtailed. The nutritional responses of parasites during host hibernation require investigation and much research will be needed to explain how perturbations in host dietary composition and intake may lead to the observed effects. Care should be exercised over applying the results from experimental studies to naturally occurring infections, but the experiments are justified because they indicate potential effects, if not their biological significance, and because causation can be determined.
