2. The Scope of Human Parasitology Parasitology claims those protozoa(single celled animals), helminths(worms)and arthropods whose existence depends on the availability of host animals It is also possible to argue about whether certain insects and mites are temporary parasites"or micro-predators'", insects as a group belong to the discipline of entomology, while ticks and mites are the concern of Acarology. The insects that are of most interest in human parasitology are those that are vectors of several parasitic infections.2.
