Infection with drug-resistant microorganisms unspecified
- tendency of biological systems (organisms, cells, or cell-free systems) to fail to respond as expected to drug treatment or exposure; may be due to specific enzymes, transporters, or receptors which block drug action.
- OBSOLETE (was not defined before being made obsolete). [GOC:go_curators]
- Diminished or failed response of an organism, disease, or tissue to the intended effectiveness of a chemical or drug. Mechanisms, functions, activities, or processes exhibited by pathogens to withstand previously toxic drugs.

Infection with drug-resistant microorganisms unspecified without multiple drug resistance

Infection with drug-resistant microorganisms unspecified with multiple drug resistance
- Adaptation of tumor cells to anticancer drugs in ways that make the drugs less effective.
- characteristic of certain cancer cells and infectious microorganisms, where resistance develops to a broad variety of chemically unrelated drugs; may be due to genetic induction of a membrane pump (P glycoprotein) or other mechanisms.
- Simultaneous resistance to a spectrum of unrelated drugs following exposure to a single agent. It may result from overexpression of the integral plasma membrane protein, P-glycoprotein. This adaptation of tumor cells to anticancer drugs, mediated by inactivation of the drug or removing it from the target tumor cells, tends to make the drugs less effective.
