The material containing microorganisms used for inoculation.
A substance used for inoculation, e.g. a vaccine.
Substance (a live, weakened, or killed virus; a toxin; or an immune serum) introduced into the body to produce or increase immunity to a specific disease; also called inoculant.
In microbiology, the substance that contains minute life forms or virus particles and is deliberately introduced into or passed on to a host or medium is referred to as “inoculum.” Additionally, this term can encompass the potentially infectious matter that exists in the soil, air, or water, which can occasionally result in the unintentional transmission of the organism to a host, also known as natural inoculation.
