Parasitology is the branch of biology concerned with the study of parasitic organisms. These organisms, known as parasites, are defined by their symbiotic relationship with a host, from which they derive nourishment and shelter, typically to the detriment of the host. Parasitology encompasses a wide range of life forms, including protozoa, helminths (worms), and ectoparasites such as arthropods.

The field investigates the biology, life cycles, ecology, and host-parasite interactions of these organisms. Understanding these aspects is crucial for developing effective strategies to control parasitic diseases in humans, animals, and plants. This includes studying how parasites infect their hosts, how they evade the host's immune system, and how they reproduce and spread.

Research in parasitology contributes significantly to public health, veterinary medicine, and agriculture. It informs the development of diagnostic tools, treatments, and preventative measures against diseases like malaria, schistosomiasis, and tapeworm infections, which affect millions worldwide. Furthermore, it plays a role in understanding biodiversity and ecosystem dynamics, as parasites are often integral components of ecological webs.
