| 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.

| acquired toxoplasmosis | In adults, a form of toxoplasmosis that may result in fever, encephalomyelitis, chorioretinopathy, maculopapular rash, arthralgia, myalgia, myocarditis, and pneumonitis; a lymphadenopathic form seems to be more prevalent in adults, and such persons may manifest fever, lymphadenopathy, malaise, and headache, a form frequently found in patients with AIDS.

| acquired trichoepithelioma | An enlarged follicular opening of the skin, with a keratinous plug and occasional lanugo or mature hair. Synonym: acquired trichoepithelioma. (05 Mar 2000) |
| community-acquired infections | Any infection acquired in the community, that is, contrasted with those acquired in a health care facility (cross infection). An infection would be classified as community-acquired if the patient had not recently been in a health care facility or been in contact with someone who had been recently in a health care facility. (12 Dec 1998) |
| murine acquired immunodeficiency syndrome | <syndrome> Acquired defect of cellular immunity that occurs in mice infected with mouse leukaemia viruses (mulv). The syndrome shows striking similarities with human aids and is characterised by lymphadenopathy, profound immunosuppression, enhanced susceptibility to opportunistic infections, and B-cell lymphomas. (12 Dec 1998) |
| 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) |
| nose deformities, acquired | Deformities of the nose acquired after birth from injury or disease. (12 Dec 1998) |
| dyslexia, acquired | Loss of previously possessed reading facility, visual aphasia, or word blindness due to a brain lesion. (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) |
| ear deformities, acquired | Distortion or disfigurement of the ear caused by disease or injury after birth. (12 Dec 1998) |
| joint deformities, acquired | Deformities acquired after birth as the result of injury or disease. The joint deformity is often associated with rheumatoid arthritis and leprosy. (12 Dec 1998) |
| feline acquired immunodeficiency syndrome | <syndrome> Acquired defect of cellular immunity that occurs in cats infected with feline immunodeficiency virus (fiv) and in some cats infected with feline leukaemia virus (felv). (12 Dec 1998) |
| foot deformities, acquired | Distortion or disfigurement of the foot, or a part of the foot, acquired through disease or injury after birth. (12 Dec 1998) |
