Viruses
The smallest known infectious agents. They can live and grow only within the living cells of other organisms.
Bacteria
Single-celled organisms that reproduce very quickly and are one of the major causes of disease. Under the right conditions-the right temperature, the right nutrients, and moisture-bacterial cells can double in number in 15 to 30 minutes.
Protozoans
Single-celled organisms that are generally much larger than bacteria. They are found in soil and water. Most do not cause disease in people. They can cause diseases such as malaria and amebic dysentery.
Fungi
Organisms that have a rigid cell wall at some stage in the life cycle. Those that grow mainly as single-celled organisms that reproduce by budding are referred to as yeasts.
Parasites
Organisms that live on or in another organism and use that other organism for their own nourishment, or for some other advantage, to the detriment of the host organism.
