| acquired sensitivity | 1. <immunology> A state of hypersensitivity induced by exposure to a particular antigen (allergen) resulting in harmful immunologic reactions on subsequent exposures, the term is usually used to refer to hypersensitivity to an environmental antigen (atopic allergy or contact dermatitis) or to drug allergy. The original meaning, now obsolete, included all states of altered immunologic reactivity, immunity as well as hypersensitivity. Gell and Coombs used the term allergic reaction to mean any harmful immunologic reaction causing tissue injury. 2. <study> The medical specialty dealing with diagnosis and treatment of allergic disorders.

| hospital acquired pneumonia | A type of pneumonia that is caused by bacteria contracted during a hospitalisation. These hospital-acquired infections tend to be more difficult to treat due to the bacteria's relative resistance to common forms of antibiotic therapy. Risk of nosocomial (hospital-acquired) infection is a major determinant when a physician decides whether or not the risks outweigh the benefits concerning necessity for hospitalisation. (27 Sep 1997) |
| simian acquired immunodeficiency syndrome | <syndrome> Acquired defect of cellular immunity that occurs naturally in macaques infected with srv serotypes, experimentally in monkeys inoculated with srv or mason-pfiser monkey virus (mpmv), or in monkeys infected with siv. (12 Dec 1998) |
