Parasitology

Parasitology is the branch of biology that focuses on the study of parasites, their hosts, and the interactions between them. Parasites are organisms that live in or on another organism (host) and derive nutrients at the expense of the host’s health. Parasitology encompasses a wide range of topics, including parasite morphology, life cycles, ecology, evolution, host-parasite interactions, and the impact of parasites on ecosystems and human health.
