| immunity | <immunology> The condition of being immune, the protection against infectious disease conferred either by the immune response generated by immunisation or previous infection or by other nonimmunologic factors. Origin: L. Immunitas (13 Oct 1997) |
|---|---|
| immunity, active | Resistance to a disease agent resulting from the production of specific antibodies by the host, either after exposure to the disease or after vaccination. (12 Dec 1998) |
| immunity, cellular | Those manifestations of the immune response which are mediated by antigen-sensitised T-lymphocytes via lymphokines or direct cytotoxicity. This takes place in the absence of circulating antibody or where antibody plays a subordinate role. (12 Dec 1998) |
| immunity deficiency | Inabillity to mount a normal immune response. Immunodeficiency can be due to a genetic disease or acquired as in aids due to HIV. (12 Dec 1998) |
| immunity, maternally-acquired | Resistance to a disease-causing agent induced by the introduction of maternal immunity into the foetus by transplacental transfer or into the neonate through colostrum and milk. (12 Dec 1998) |
| immunity, mucosal | Nonsusceptibility to the pathogenic effects of foreign microorganisms or antigenic substances as a result of antibody secretions of the mucous membranes. Mucosal epithelia in the gastrointestinal, respiratory, and reproductive tracts produce a form of IgA (IgA, secretory) that serves to protect these ports of entry into the body. (12 Dec 1998) |
| infection immunity | The paradoxical immune status in which resistance to reinfection coincides with the persistence of the original infection. Synonym: concomitant immunity. (05 Mar 2000) |
| innate immunity | This includes local barriers to infection such as skin, stomach acid, mucous, the cough reflex, enzymes in tears and saliva and skin oils. (27 Sep 1997) |
| local immunity | A natural or acquired immunity to certain infectious agents, as manifested by an organ or a tissue, as a whole or in part. (05 Mar 2000) |
| passive | Neither spontaneous nor active, not produced by active efforts. Origin: L. Passivus (18 Nov 1997) |
| passive agglutination | Agglutination of particles that have been coated with soluble antigen, by antiserum specific for the adsorbed antigen. Synonym: indirect agglutination. (05 Mar 2000) |
| passive-aggressive behaviour | Apparently compliant behaviour, with intrinsic obstructive or stubborn qualities, to cover deeply felt aggressive feelings that cannot be more directly expressed. (05 Mar 2000) |
| passive-aggressive personality | A personality disorder in which aggressive feelings are manifested in passive ways, especially through mild obstructionism and stubbornness. (05 Mar 2000) |
| passive-aggressive personality disorder | A personality disorder characterised by an indirect resistance to demands for adequate social and occupational performance; anger and opposition to authority and the expectations of others that is expressed covertly by obstructionism, procrastination, stubbornness, dawdling, forgetfulness, and intentional inefficiency. (12 Dec 1998) |
| passive anaphylaxis | A reaction resulting from inoculation of antigen in an animal previously inoculated intravenously with specific antiserum from another animal, a latent period being required between the two inoculations. Synonym: antiserum anaphylaxis. (05 Mar 2000) |
