| acute post-streptococcal glomerulonephritis | <nephrology> A disease of the kidneys that results in inflammation of the glomerulus (the portion of the kidney that filters the blood). Conditions which may cause glomerulonephritis include post-streptococcal disease (strep throat), lupus, syphilis, bacterial endocarditis, membranoproliferative glomerulonephritis, sepsis, vasculitis, Goodpasture's syndrome, typhoid fever, Henoch-Schonlein purpura, hepatitis or a viral infection (for example mumps, measles, mononucleosis).

| group A streptococcal necrotizing fasciitis | A complication of infection with GAS (group A streptococci) in which the bacteria attacks and destroys muscle tissue. According to the CDC, 5-10% of people with severe GAS infection develop necrotizing fasciitis. Though the infection can be treated with antibiotics, the fatality rate is close to 30%. This complication often develops as a wound infection after surgery or injury. (05 Mar 2000) |
| streptococcal | Relating to or caused by any organism of the genus Streptococcus. (05 Mar 2000) |
| streptococcal fibrinolysin | <enzyme> Plasminogen activator released by Streptococcus pyogenes. Occurs in two forms, A and B. (18 Nov 1997) |
| streptococcal infections | Infections with bacteria of the genus streptococcus. (12 Dec 1998) |
| streptococcal lymphadenitis | A contagious bacterial disease of pigs caused by a group E streptococcus and characterised by the formation of abscesses in the cervical and/or cephalic lymph nodes. (05 Mar 2000) |
| streptococcal nuclease | <enzyme> From streptococcus haemolyticus; degrades RNA and DNA producing oligonucleotides terminating in 5'-phosphate Registry number: EC 3.1.30.- (26 Jun 1999) |
| streptococcal pneumonia | Pneumonia due to Streptococcus pyogenes. (05 Mar 2000) |
| streptococcal toxins | Group of haemolytic exotoxins released by Streptococci. _ haemolysin: 26-39 Kd (four types), forms ring like structures in membranes (see Streptolysin O). Lipid target unclear. _ haemolysin: a hot cold haemolysin with sphingomyelinase C activity. _ haemolysin: complex of two proteins (29 and 26 kD) that act synergistically, rabbit erythrocytes particularly sensitive. _ toxin: heat stable peptide (5 kD) with high proportion of hydrophobic amino acids. Seems to act in a detergent like manner (c.f. Subtilysin), but may form hydrophilic transmembrane pores by cooperative interaction with other _ toxin molecules. Leucocidin (Panton Valentine leucocidin): two components f (fast migration on CM cellulose column: 32 kD) and s (slow: 38 kD). Mode of action contentious. See: Streptococcus, streptolysins O and S, erythrogenic toxin. (18 Nov 1997) |
| acute necrotizing ulcerative gingivitis | An acute or recurrent gingivitis of young and middle-aged adults characterised clinically by gingival erythema and pain, fetid odour, and necrosis and sloughing of interdental papillae and marginal gingiva which gives rise to a gray pseudomembrane; fever, regional lymphadenopathy, and other systemic manifestations also may be present. A fusiform bacillus and Treponema vincentii can be isolated from the gingival tissues in large numbers and are felt to play a significant but poorly defined role in the pathogenesis. Synonym: fusospirochetal gingivitis, trench mouth, ulceromembranous gingivitis, Vincent's disease, Vincent's infection. (05 Mar 2000) |
| atypical gingivitis | Intense hyperaemic oedema and inflammation of the gingiva resulting from a hypersensitivity reaction. A dense plasma cell infiltrate is seen in the lamina propria. Synonym: atypical gingivitis. (05 Mar 2000) |
| marginal gingivitis | Gingivitis in which the clinical alterations are confined to the marginal gingiva and do not involve the attached gingiva. (05 Mar 2000) |
| gingivitis | <pathology> Inflammation of the gingivae. Gingivitis associated with bony changes is referred to as periodontitis. Synonym: oulitis, ulitis. (18 Nov 1997) |
| gingivitis, necrotizing ulcerative | An acute or chronic gingival infection characterised by redness and swelling, necrosis extending from the interdental papillae along the gingival margins, pain, haemorrhage, necrotic odour, and often a pseudomembrane. The condition may extend to the oral mucosa, tongue, palate, or pharynx. (12 Dec 1998) |
| chronic desquamative gingivitis | A clinical term for a gingival condition of unknown aetiology, usually encountered in middle-aged and older women, characterised by erythema, mucosal atrophy, and desquamation, and usually accompanied by a burning sensation and pain; diagnosis is usually made by biopsy and direct immunofluorescence. Synonym: gingivosis. (05 Mar 2000) |
