| intestinal villi | <pathology> Microscopic finger-like projections (0.5 to 1.5 mm in length) off of the mucosal lining of the small intestine which are responsible for absorption of nutrients. The villi greatly increase the effective absorptive surface area of the small intestine. (27 Sep 1997) |

| juxta-intestinal lymph nodes | The mesenteric lymph nodes located in immediate proximity to the jejunum or ileum. Synonym: nodi lymphatici juxta-intestinales. (05 Mar 2000) |
| familial intestinal polyposis | Begins usually in late childhood; polyps increase in numbers, causing symptoms of chronic colitis, and carcinoma of the colon almost invariably develops in untreated cases; autosomal dominant inheritance. In the Gardner syndrome there are extracolonic changes (desmoid tumours, etc.). Synonym: polyposis coli. Hamartomatous polyposis of the small or large intestine, Peutz-Jeghers syndrome with melanin spots on the lips, less common, miscellaneous, rare, and doubtful occurrences. Synonym: familial intestinal polyposis. (05 Mar 2000) |
| lieno-intestinal | <anatomy> Of or pertaining to the spleen and intestine; as, the lieno-intestinal vein of the frog. Origin: l. Lien the spleen + E. Intestinal. Source: Websters Dictionary (01 Mar 1998) |
| lipophagic intestinal granulomatosis | An obsolete term for Whipple's disease. (05 Mar 2000) |
| lymphangiectasis, intestinal | Dilatation of the intestinal lymphatic system, particularly in the lacteals in the intestinal villi, characterised by protein-losing enteropathy, steatorrhoea, and lymphopenia. It may be congenital, due to abnormality of the lymphatic system (as in milroy's disease) or acquired, due to involvement of the major intestinal lymphatic ducts by inflammatory processes or neoplasm, or to increased lymphatic pressure, as in valvular heart disease and constrictive pericarditis. (12 Dec 1998) |
| 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) |
