Medical parasitology studies parasites that infect humans and the relationship between parasites and their human hosts. It covers the morphology, lifecycle, pathogenesis, diagnosis, treatment, transmission, and prevention of parasitic diseases. Parasites are classified as protozoa, helminthes, or arthropods. Protozoa are unicellular parasites while helminthes and arthropods are multicellular. The study of protozoans is called protozoology, which began in the late 17th century when protozoans were first observed under microscopes. Protozoans also serve as experimental models in cell and molecular biology research.

1. Introduction into
parasitology

2.  What is Medical Parasitology?
Medical parasitology or human parasitology is restricted to
studying those parasites that are living in or on the body of
humans and with aspects of the host-parasite relationship
having medical significance. In other words, medical
parasitology is the subject which deals with the parasites
that infect man, the diseases caused by them, clinical
picture and the response generated by man against them.

17. Protozoology, the study of
protozoans. The science had its
beginnings in the latter half of the
17th century when Antonie van
Leeuwenhoek of the Netherlands
first observed protozoans by
means of his invention, the
microscope.

18. Protozoans also serve as
experimental organisms in many
studies of cell and molecular
biology.
