| resistance-transferring episomes | 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, vascular | The opposition to the flow of blood across a vascular bed. (12 Dec 1998) |
| cephalosporin resistance | <microbiology> Non-susceptibility of an organism to the action of the cephalosporins. (12 Dec 1998) |
| penicillin resistance | <microbiology, pharmacology> Nonsusceptibility of an organism to the action of penicillins. (12 Dec 1998) |
| peripheral resistance | The total resistance to flow of blood in the systemic circuit; the quotient produced by dividing the mean arterial pressure by the cardiac minute-volume. Synonym: peripheral resistance. (05 Mar 2000) |
| chloramphenicol resistance | <microbiology, pharmacology> Nonsusceptibility of a bacterium to the action of chloramphenicol, a potent inhibitor of protein synthesis in the 50s ribosomal subunit where amino acids are added to nascent bacterial polypeptides. (12 Dec 1998) |
| methicillin resistance | Non-susceptibility of a microbe to the action of methicillin, a semi-synthetic penicillin derivative. (12 Dec 1998) |
| multidrug resistance | The insensitivity of various tumours to a variety of chemically related anticancer drugs; mediated by a process of inactivating the drug or removing it from the target tumour cells. (05 Mar 2000) |
| mutual resistance | An interaction between chemicals in which one partially or completelyinhibits the effect of the other (for example, a drug that blocks a hormone's receptor site would be a hormone antagonist). (09 Oct 1997) |
| cross-resistance | <immunology, microbiology> Immunologic resistance to the pathogenic effects of a microorganism because of previous exposure to another species or type having cross reactive antigens. This phenomenon is seen in microbes that acquire resistance to one drug through direct exposure and turn out to have resistance to one or more other drugs to which it has not been exposed. Cross-resistance arises because the mechanism of resistance to several drugs is the same and arises through the identical genetic mutations. (09 Oct 1997) |
| sisomicin-gentamicin resistance ribosomal RNA methylase | <enzyme> Catalyses the methylation of 30s ribosomal units to confer sisomicin-gentamicin resistance in micromonospora zionensis Registry number: EC 2.1.1.- Synonym: sgm gene product, sgm methylase (26 Jun 1999) |
| synaptic resistance | The ease or difficulty with which a nerve impulse can cross a synapse. (05 Mar 2000) |
| systemic vascular resistance | An index of arteriolar compliance or constriction throughout the body; equal to the blood pressure divided by the cardiac output. (05 Mar 2000) |
| dicumarol resistance | A well-defined autosomal dominant resistance to it, over and above general variability in tolerance to the drug. (05 Mar 2000) |
| drug resistance | The ability of bacteria and other microorganisms to withstand a drug to which they were once sensitive (and were once stalled or killed outright). (12 Dec 1998) |
