| primary atypical pneumonia | An acute systemic disease with involvement of the lungs, caused by Mycoplasma pneumoniae and marked by high fever, cough, relatively few physical signs, and scattered densities on X-rays; usually associated with development of cold agglutinins and antibodies to the bacteria. Synonym: atypical pneumonia, Eaton agent pneumonia, mycoplasmal pneumonia. (05 Mar 2000) |

| Hecht's pneumonia | A rare complication of measles, with the postmortem finding of multinucleated giant cells lining alveoli. Synonym: Hecht's pneumonia, interstitial giant cell pneumonia. (05 Mar 2000) |
| progressive pneumonia | A chronic progressive, viral disease of sheep and goats manifested as maedi or visna in different parts of the world. See: maedi, visna. (05 Mar 2000) |
| progressive pneumonia virus | A retrovirus (subfamily Lentivirinae) that is the cause of maedi; it is very similar to the visna virus Synonym: medi virus, progressive pneumonia virus. (05 Mar 2000) |
| 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) |
| purulent pneumonia | Pneumonia caused by an organism that produces pus, implying that there can be destruction of lung tissue with permanent changes; usually sputum contains pus. Staphylococci, haemolytic streptococci, and Friedlander's bacillus are typical causes, as opposed to Streptococcus pneumoniae, which is rarely a cause of purulent pneumonia. (05 Mar 2000) |
| septic pneumonia | Any pneumonia associated with the formation of pus and destruction of pulmonary tissue; abscess formation may occur. Synonym: septic pneumonia. (05 Mar 2000) |
| hypostatic pneumonia | Pneumonia resulting from infection developing in the dependent portions of the lungs due to decreased ventilation of those areas, with resulting failure to drain bronchial secretions; occurs primarily in the aged or those debilitated by disease who lie in the same position for long periods. (05 Mar 2000) |
| staphylococcal pneumonia | Pneumonia, usually caused by Staphylococcus aureus, usually commencing as a bronchopneumonia, and frequently leading to suppuration and destruction of lung tissue. (05 Mar 2000) |
| streptococcal pneumonia | Pneumonia due to Streptococcus pyogenes. (05 Mar 2000) |
| nosocomial pneumonia | <chest medicine> 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. (13 Nov 1997) |
| suppurative pneumonia | Any pneumonia associated with the formation of pus and destruction of pulmonary tissue; abscess formation may occur. Synonym: septic pneumonia. (05 Mar 2000) |
| deglutition pneumonia | <chest medicine> Refers to the inappropriate passage of food, water, stomach acid, vomit or another foreign material into the lungs. Aspiration, particularly involving gastric acid, will often result in a serious pneumonia. (27 Sep 1997) |
| desquamative interstitial pneumonia | Diffuse proliferation of alveolar epithelial cells, which desquamate into the air sacs and become filled with macrophages, accompanied by interstitial cellular infiltration and fibrosis; gradual onset of dyspnea and nonproductive cough occurs. (05 Mar 2000) |
| desquamative pneumonia | Relatively rare form of pneumonia with homogeneous filling of alveolar air spaces with macrophages and a few type II epithelial lining cells, some alveolar septal infiltration with inflammatory and connective tissue cells. Usually idiopathic but some cases have been reported in association with drugs or underlying systemic connective tissue disease. Rarely progresses to end-stage lung disease. (05 Mar 2000) |
