GENERAL PARASITOLOGY LEARNING OBJECTIVES

INTRODUCTION
Man and other living things on earth live in an entangling relationship with each other .They don’t exist in an isolated fashion. They are interdependent; each forms a strand in the web of life. Medical parasitology is the science that deals with organisms living in the human body (the host) and the medical significance of this host-parasite relationship.
ASSOCIATION BETWEEN PARASITE AND HOST
A parasite is a living organism, which takes its nourishment and other needs from a host ; the host is an organism which supports the parasite. The parasites included in medical parasitology are protozoa, helminthes, and some arthropods. broader classification of parasites). The hosts vary depending on whether they harbor the various stages in parasitic development.
