Abstract
Only a small proportion of the microorganisms that abount in nature are pathogenic for man. Most are free living in soil, water and similar habitats, and are unable to invade the living body. In contrast, a parasite is defined as a microorganism that lives in or and obtains its nourishment form a living host. Parasitic mircoorganisms can either be commensals or pathogens. Commensals, constitute the normal flora of the healthy body and live on the skin, mucous membranes of the upper respiratory tract, intestine and vagina, and obtain nourishment from the secretions and food recidues. Since normally they do not invade the blood or tissues, they are generally harmless, but under certain circumstances, as when the body's defences are impaired, they may in vade the tissuses and cause disease, thus acting as apportunity pathogens. True pathogens are the parasitic microorganisms that manage to overcome the normal defenced of the body and invade the tissue.
