a substance (a virus or toxin or immune serum) that is introduced into the body to produce or increase immunity to a particular disease

a highly concentrated suspension of yeast (or other microorganisms) to be added to malt mashes for beer-making or to bread doughs for leavening purposes or wherever fermentation is desired

Material (usually cells) introduced into a media to initaite growth of culture. Back to glossary index

The microorganisms or other material used to cause an infection. Also called inoculant.

Cells added to start a culture or, in the case of viruses, viruses added to infect a culture of cells. Also, biological material injected into a human to induce immunity (a vaccine).

1. Bacteria or fungi injected into compost to start biological action. 2. A medium containing organisms, usually bacteria or a virus, that is introduced into cultures or living organisms.
