Which term describes the ability to resist a particular infection or toxin by antibodies or sensitized white blood cells?

• A. Immunity
• B. Infectious disease
• C. Reservoir
• D. Virulence

Answer: (A)

Immunity. The body's ability to resist a specific infection or toxin by antibodies or sensitized white blood cells. Antibodies from B cells and the cell-mediated actions of T cells work together to recognize, neutralize, or eliminate pathogens. Immunity can be acquired actively (the body makes its own antibodies and memory after exposure or vaccination) or passively (temporary protection provided by another source’s antibodies or immune cells). This is different from an infectious disease (the illness itself), a reservoir (where a pathogen persists), or virulence (how harmful a pathogen is).
