| pseudomembranous | <anatomy> Marked by or pertaining to a pseudomembrane. (18 Nov 1997) |
|---|---|
| pseudomembranous bronchitis | Inflammation of the bronchial mucous membrane, accompanied by a fibrinous exudation, which often forms a cast of the bronchial tree with severe obstruction of air flow. Synonym: plastic bronchitis, pseudomembranous bronchitis. (05 Mar 2000) |
| pseudomembranous colitis | <gastroenterology> A form of gastroenteritis which occurs when there is an over-growth of Clostridium difficile bacteria in the intestine. This can occur after long-term treatment with broad spectrum antibiotics. (25 Nov 1998) |
| pseudomembranous conjunctivitis | A non-specific inflammatory reaction characterised by the appearance on the conjunctiva of a coagulated fibrinous plaque that may be peeled off from intact epithelium. (05 Mar 2000) |
| pseudomembranous enteritis | Enterocolitis with the formation and passage of pseudomembranous material in the stools; occurs most commonly as a sequel to antibiotic therapy; caused by a necrolytic exotoxin made by Clostridium difficile. Synonym: pseudomembranous colitis, pseudomembranous enteritis. (05 Mar 2000) |
| pseudomembranous enterocolitis | Enterocolitis with the formation and passage of pseudomembranous material in the stools; occurs most commonly as a sequel to antibiotic therapy; caused by a necrolytic exotoxin made by Clostridium difficile. Synonym: pseudomembranous colitis, pseudomembranous enteritis. (05 Mar 2000) |
| pseudomembranous gastritis | Gastritis characterised by the formation of a false membrane. (05 Mar 2000) |
| pseudomembranous inflammation | A form of exudative inflammation that involves mucous and serous membranes; relatively large quantities of fibrin in the exudate result in a rather tenacious membrane-like covering that is fairly adherent to the underlying acutely inflamed tissue; the pseudomembrane usually contains (in addition to the dense network of fibrin) varying quantities of plasma protein, degenerated and necrotic elements from the affected tissue, polymorphonuclear leukocytes, bacteria, etc. (05 Mar 2000) |
| pseudomeningitis | The symptoms and signs of meningeal irritation associated with acute febrile illness or dehydration without actual infection of the meninges. (12 Dec 1998) |
| pseudomenstruation | Uterine bleeding without the typical premenstrual endometrial changes. (05 Mar 2000) |
| pseudometaplasia | The change in shape of cells to meet altered physical conditions, as the flattening of cuboidal cells in cysts as a result of pressure. Synonym: pseudometaplasia. (05 Mar 2000) |
| pseudomnesia | A subjective impression of memory of events that have not occurred. Origin: pseudo-+ G. Mnesis, memory (05 Mar 2000) |
| pseudomonad | <bacteria> Member of the genus Pseudomonas, a large group of Gram-negative, obligately respiratory (never fermentative) bacteria. (25 Nov 1998) |
| pseudomonadaceae | A family of gram-negative bacteria usually found in soil or water and including many plant pathogens and a few animal pathogens. (12 Dec 1998) |
| Pseudomonas | <bacteria> Genus of gram-negative bacteria. They are rod shaped and are motile, possessing one or more polar flagella. Several species produce characteristic water soluble fluorescent pigments. They are found in soil and water. Pseudomonas syringae is a plant pathogen causing leaf spot and wilt. Pseudomonas aeruginosa, normally a soil bacterium, is an opportunistic pathogen of humans who are immunocompromised. It can infect the wounds of victims with severe burns, causing the formation of blue pus. (18 Nov 1997) |
