| diarrhoea, antibiotic-induced | A bacterium called Clostridium difficile (C.difficile), one of the most common causes of infection of the large bowel (colon). Patients taking antibiotics are at particular risk of becoming infected with C. Difficile. Antibiotics disrupt the normal bacteria of the bowel, allowing C. Difficile bacteria (and other bacteria) to become established and overgrow the colon. Many persons infected with C. Difficile bacteria have no symptoms but can become carriers of the bacteria and infect others. In other people, a toxin produced by C. Difficile causes diarrhoea, abdominal pain, severe inflammation of the colon (colitis), fever, an elevated white blood count, vomiting and dehydration. In severely affected patients, the inner lining of the colon becomes severely inflamed (a condition called pseudomembranous colitis). Rarely, the walls of the colon wear away and holes develop (colon perforation), which can lead to a life-threatening infection of the abdomen. (12 Dec 1998) |

| transport antibiotic | A substance that makes biomembranes permeable to certain ions. (05 Mar 2000) |
| airway resistance | The opposition of the tracheobronchial tree to air flow: the mouth-to-alveoli pressure difference divided by the air flow. (12 Dec 1998) |
| ampicillin resistance | Nonsusceptibility of a microbe to the action of ampicillin, a penicillin derivative that interferes with cell wall synthesis. (12 Dec 1998) |
| androgen resistance syndromes | A class of disorders associated with 5a-steroid reductase deficiency, testicular feminization, and related disorders. Compare: steroid 5a-reductase, Reifenstein's syndrome, infertile male syndrome, testicular feminization syndrome. (05 Mar 2000) |
| bacteriophage resistance | Resistance of a bacterial mutant to infection by a bacteriophage to which the parent (wild type) strain is susceptible. (05 Mar 2000) |
| beta-lactam resistance | Nonsusceptibility of an organism to the action of the beta-lactam antibiotics. (12 Dec 1998) |
| capillary resistance | The resistance offered to the flow of blood through the capillary portion of the peripheral vascular bed. (12 Dec 1998) |
| capillary resistance test | A tourniquet test used to determine presence of vitamin C deficiency or thrombocytopenia; a circle 2.5 cm in diameter, the upper edge of which is 4 cm below the crease of the elbow, is drawn on the inner aspect of the forearm, pressure midway between the systolic and diastolic blood pressure is applied above the elbow for 15 minutes, and a count of petechiae within the circle is made: 10, normal; 10 to 20, marginal zone; over 20, abnormal. See: Rumpel-Leede test. Synonym: capillary resistance test, vitamin C test. (05 Mar 2000) |
| vascular resistance | An expression of the resistance offered by the systemic arterioles, and to a lesser extent by the capillaries, to the flow of blood. (12 Dec 1998) |
| resistance | The failure of a condition to respond or remit following treatment. (16 Dec 1997) |
| resistance factor | <molecular biology> A self-replicating fragment of nucleic acid that confers drug resistance and is transmitted from one bacterium to another via conjugation. (09 Oct 1997) |
| resistance factors | Plasmid's carrying genes responsible for antibiotic (or antibacterial drug) resistance among bacteria (notably Enterobacteriaceae); they may be conjugative or nonconjugative plasmid's, the former possessing transfer genes (resistance transfer factor) lacking in the latter. Synonym: R factors, R plasmids, resistance factors, resistance-transferring episomes. (05 Mar 2000) |
| resistance form | The shape given to a cavity preparation that enables the dental restoration to withstand masticatory forces. (05 Mar 2000) |
| resistance-inducing factor | An agent from normal chick embryos that interferes with multiplication of the avian leukosis-sarcoma virus, and is seemingly an avirulent leukosis virus antigenically related to the avian leukosis-sarcoma virus. (05 Mar 2000) |
