Minimal infective dose

From Wikipedia, the free encyclopedia

This is an old revision of this page, as edited by 137.224.252.10 (talk) at 09:10, 22 September 2015 (Infectious doses for some known microorganisms). The present address (URL) is a permanent link to this revision, which may differ significantly from the current revision.

Infectious dose (ID) is the amount of pathogen (measured in number of microorganisms) required to cause an infection in the host.[1]

Usually it varies according to the pathogenic agent and the consumer's age and overall health.

Infectious doses for some known microorganisms

The likelihood of infection in all cases is also linked to the immune status of the individual (immunocompromised individuals may become infected more readily).[4]
