Parasitology is the scientific discipline that investigates parasites—organisms that live in or on a host and derive resources at the host’s expense—along with their hosts and the environments that shape these interactions. It encompasses the biology, life cycles, genetics, ecology, and evolution of protozoan, helminth, and arthropod parasites, as well as host immune responses and mechanisms of pathogenesis. Parasitology underpins diagnosis, treatment, and prevention of parasitic diseases in humans, animals, and plants, integrating tools from molecular biology, immunology, epidemiology, and vector biology to elucidate transmission dynamics, drug resistance, and control strategies.
