| staphylococcus epidermidis | A species of staphylococcus that is a spherical, non-motile, gram-positive, chemoorganotrophic, facultative anaerobe. Mainly found on the skin and mucous membrane of warm-blooded animals, it can be primary pathogen or secondary invader. (12 Dec 1998) |
|---|
| stratum basale epidermidis | The deepest layer of the epidermis, composed of dividing stem cells and anchoring cells. Synonym: basal cell layer, columnar layer, germinative layer, palisade layer, stratum basale, stratum cylindricum, stratum germinativum. (05 Mar 2000) |
|---|---|
| stratum corneum epidermidis | The outer layer of the epidermis, consisting of several layers of flat keratinised non-nucleated cells. Synonym: corneal layer of epidermis, horny layer of epidermis. (05 Mar 2000) |
| stratum granulosum epidermidis | A layer of somewhat flattened cells containing basophilic granules of keratohyalin and lying just above the stratum spinosum and deeply to the stratum corneum. Synonym: stratum granulosum epidermidis. (05 Mar 2000) |
| stratum spinosum epidermidis | The layer of polyhedral cells in the epidermis; shrinkage artifacts and adhesion of these cells at their desmosomal junctions gives a spiny or prickly appearance. Synonym: prickle cell layer, spinous layer. (05 Mar 2000) |
| Staphylococcus | <bacteria> Genus of nonmotile gram-positive bacteria that are found in clusters and that produce important exotoxins. Staphylococcus aureus (Staphylococcus pyogenes) is pyogenic, an opportunistic pathogen and responsible for a range of infections including severe sepsis, pneumonia, endocarditis and soft tissue infections. It has protein A on the surface of the cell wall. Coagulase production correlates with virulence: hyaluronidase, lipase and staphylokinase are released in addition to the toxins. (27 Sep 1997) |
| staphylococcus antitoxin | A preparation from native serum containing antitoxic globulins or their derivatives that specifically neutralise the lethal, skin-necrosing, and haemolytic properties of the alpha-toxin of Staphylococcus aureus. (05 Mar 2000) |
| staphylococcus aureus | Potentially pathogenic bacteria found in nasal membranes, skin, hair follicles, and perineum of warm-blooded animals. They may cause a wide range of infections and intoxications. (12 Dec 1998) |
| Staphylococcus aureus neutral proteinase | <enzyme> Included in the group of microbial metalloproteinases EC 3.4.24.4; ptrb protein is isolated from E coli; sakstar is recombinant staphylokinase Pharmacological action: fibrinolytic agents Registry number: EC 3.4.24.- Synonym: protease II, staphylokinase, staph aureus protease, staphylococcal protease, E coli protease, ptrb protein, sakstar, (26 Jun 1999) |
| Staphylococcus food poisoning | Outbreaks commonly caused by staphylococcal enterotoxin and characterised by an abrupt onset of gastroenteritis within several hours after ingestion of the food contaminated with the preformed exotoxin; vomiting is usually more severe and diarrhoea less severe than in infectious forms of bacterial food poisoning. (05 Mar 2000) |
| Staphylococcus haemolyticus | Coagulase-negative staphylococcus indigenous to human and mammalian hosts. (05 Mar 2000) |
| Staphylococcus hominis | Coagulase-negative staphylococcus indigenous to human and mammalian hosts. (05 Mar 2000) |
| Staphylococcus hyicus | A species whose porcine subspecies are opportunistic pathogens associated with epidermites such as greasy pig disease. (05 Mar 2000) |
| staphylococcus phages | Viruses whose host is staphylococcus. (12 Dec 1998) |
| Staphylococcus pyogenes albus | A name formerly applied to the organisms which are now regarded as the mutants of Staphylococcus aureus which form white colonies. (05 Mar 2000) |
| Staphylococcus pyogenes aureus | Potentially pathogenic bacteria found in nasal membranes, skin, hair follicles, and perineum of warm-blooded animals. They may cause a wide range of infections and intoxications. (12 Dec 1998) |
