Overview
Parasites are organisms that live in or on other organisms for their entire life cycle, dependent on their host for nutrition, sustenance and often for protection from predators. Ecology of parasites is the study of the interactions between parasites and their environment. This field is important not only for understanding the biology of parasites, but also for providing important information on their role in ecosystems, as well as their potential to cause or contribute to disease. Parasites can cause significant damage to their host, whether through direct feeding damage, modifications of the host’s behavior, or by carrying other diseases. A better understanding of parasite ecology can help inform strategies for preventing or minimizing the impacts of parasites, including the implementation of improved sanitation measures, vector control and more effective vaccination strategies.
