The two main groups of parasites are the microparasites and the macroparasites. Protozoa are microparasites as they multiply within the host.

The number of macroparasites in the body reflects the number which invaded the animal.

INFECTIOUS AGENTS AND PARASITES



Introduction

Parasitology is the study of parasites, their hosts and the relationship between the two. Parasitology, as opposed to microbiology is generally concerned with eukaryote organisms. The parasitic mode of life is the most common on the planet and the number of parasitic species greatly exceeds the number of free-living hosts.

Understanding parasitology is crucial to veterinarians. Identification, control and treatment will be part of the daily routine for most vets, from common problems such as fleas on domestic animals, seasonal outbreaks of worms in livestock and tick problems in wildlife.

Clinical disease is often only the tip of the iceberg in a parasitic infection as the effects on the host are not readily seen on examination. Sub-clinical disease is often only seen as a decrease in productivity of the animal, for example, reduced weight gain, reduced milk yield and decreased quality of milk, hide or wool.

In this parasitology section, entomology, protozoology and helminthology will be described with the most important veterinary species covered in greater details than the lesser important parasites. Anthelmintics, antiparasiticides and the immune response to parasitic infection are covered elsewhere on the wiki and should be used to reinforce how parasites can be treated and controlled.
