organisms living on a host's surface, causing irritation or disease
Ectoparasites, also known as external parasites, are organisms that live on the surface of a host and derive their nutrients at the host's expense. Common examples include lice, fleas, and ticks, which can cause various skin irritations and transmit diseases. These parasites are of particular concern in both human and veterinary medicine due to their impact on health and well-being.
