| bacterial peliosis | A bacterial infection of haemorrhagic cysts of the liver, spleen, or lymph nodes, seen in immunocompromised persons, caused by Rochalimaea henselae. (05 Mar 2000) |
|---|
| peliosis | <clinical sign, dermatology> A small haemorrhage (up to about 1 cm in diameter) in the skin, mucous membrane or serosal surface, which may be caused by various factors, including blood disorders, vascular abnormalities and trauma. Purpuric lesions may be associated with inflammation, in which case they present as papular purpura or the haemorrhage may not be accompanied by inflammation, in which case they are macular. The term also comprises a group of haemorrhagic diseases characterised by the presence of purpuric lesions, ecchymoses and a tendency to bruise easily, which may be caused by decreased platelet counts, the presence of abnormal platelets, vascular defects or reactions to certain drugs. (15 Dec 1997) |

| peliosis hepatis | <radiology> Benign, intrahepatic vascular disorder, associated with benign and malignant liver tumours, possible vasodilatory response to sex hormones, (?) clinical significance, multiple endothelium-lined, blood-filled spaces, communicate with sinusoids, angio (parenchymal phase): multiple round collections of contrast in liver (3 - 15 mm), Differential diagnosis: focal nodular hyperplasia, hypervascular metastasis, cavernous haemangiomata (12 Dec 1998) |
| peliosis hepatitis | A rare condition in which the liver contains very numerous small blood-filled spaces, sometimes lined with endothelium; it may be found incidentally or rupture may cause intraperitoneal haemorrhage. (05 Mar 2000) |
| acute bacterial endocarditis | A type of bacterial endocarditis caused by pyogenic organisms such as haemolytic streptococci or staphylococci. (05 Mar 2000) |
| adhesins, bacterial | Cell-surface components or appendages of bacteria that facilitate adhesion (bacterial adhesion) to other cells or to inanimate surfaces. most fimbriae (fimbriae, bacterial) of gram-negative bacteria function as adhesins, but in many cases it is a minor subunit protein at the tip of the fimbriae that is the actual adhesin. In gram-positive bacteria, a protein or polysaccharide surface layer serves as the specific adhesin. (12 Dec 1998) |
| antibodies, bacterial | Immunoglobulins induced by substances elaborated by bacteria that have an antigenic activity. (12 Dec 1998) |
| antigens, bacterial | Substances elaborated by bacteria that have antigenic activity. (12 Dec 1998) |
| atypical bacterial forms | Microorganisms that have undergone greater changes than normal in morphology, physiology, or cultural characteristics. (12 Dec 1998) |
| bacteria-free stage of bacterial endocarditis | Endocarditis described prior to the antibiotic era and presumably due to spontaneous healing of the bacterial vegetations. (05 Mar 2000) |
| bacterial | <microbiology> Bacteria are group of micro-organisms that are a single cell approximately 1 micron in transverse diameter. Some bacteria cause disease in man, requiring treatment with an antibiotic. (27 Sep 1997) |
| bacterial adhesion | Physicochemical property of fimbriated (fimbriae, bacterial) and non-fimbriated bacteria of attaching to cells, tissue, and nonbiological surfaces. It is a factor in bacterial colonization and pathogenicity. (12 Dec 1998) |
| bacterial allergy | The concept that the atopic kind of type I allergic reactions may be caused by bacterial allergens, the delayed type of skin test, so-called because of its early association with bacterial antigens (e.g., the tuberculin test). (05 Mar 2000) |
| bacterial antagonism | The inhibition of one bacterium by products of another. (05 Mar 2000) |
| bacterial capsule | A layer of slime of variable composition which covers the surface of some bacteria; capsulated cells of pathogenic bacteria are usually more virulent than cells without capsules because the former are more resistant to phagocytic action. (05 Mar 2000) |
| bacterial capsules | An envelope of loose gel surrounding a bacterial cell which is associated with the virulence of pathogenic bacteria. Some capsules have a well-defined border, whereas others form a slime layer that trails off into the medium. most capsules consist of relatively simple polysaccharides but there are some bacteria whose capsules are made of polypeptides.
