👉 In the context of medicine, a "holoparasitic" refers to a parasite that is parasitized by an organism other than its natural host. This can occur in both animals and humans. In some cases, it may be a parasitic infection caused by a protozoan or a nematode, which are parasites that live on the body of their host. These parasites often require a specific environment for growth and reproduction, such as soil or water, to thrive.
