Minimal lethal dose (medicine)


minimal lethal dose
<pharmacology> The minimal dose of a toxic substance or infectious agent that is lethal, as assayed in various experimental animals (e.g., the least amount of diphtheria toxin that, on an average, kills a 250-g guinea pig within 96 hours after subcutaneous inoculation).

When followed by a subscript (generally "MLD50"), denotes the minimal dose that is lethal to a certain percentage (e.g., 50%) of animals so assayed, LD05.
