The ability of some disease-causing microorganisms, such as bacteria to adapt themselves to grow and to multiply even in the presence of drugs that kill them.
The ability of bacteria, viruses and other illness-causing agents to adapt to treatments and continue to grow or multiply. When HIV becomes resistant (less sensitive) to an HIV med (as determined by a genotype or phenotype resistance test) it is necessary to change treatment.
the failure of ( cancer) cells to respond to drugs ( chemotherapy).
The ability of a tumor cell to survive in the presence of drugs that are normally toxic.
A condition in which a person's cancer cells no longer respond to chemotherapy.
The development of resistance in cancer cells to a specific drug or drugs. If resistance develops, a patient in remission from chemotherapy may relapse despite continued administration of anticancer drugs.
Normal or tumor cells that are able to survive when exposed to a variety of drugs.
Condition where cancer cells have developed the ability to prevent being killed by cancer cells.
Occurs when the virus a person is infected with is no longer sensitive to the medications taken. Even when the viral load is undetectable, a small amount of virus is still replicating. The 'copies' (of the replicating viruses) that survive are those that the drug cannot suppress. The surviving copies have genes that have mutated to elude capture by the drug. Sooner or later, this mutated virus reaches a critical mass and 'breaks through'[See Reading Test Results].
refers to the ability of cancer cells to become resistant to the effects of the chemotherapy drugs used to treat cancer.
Drug resistance is the result of microbes changing in ways that reduce or eliminate the effectiveness of drugs, chemicals, or other agents to cure or prevent infections.
When a virus is able to adapt, grow, and multiply in the presence of drugs designed to kill it.
The ability of bacteria and other microorganisms to withstand a drug to which they were once sensitive (and were once stalled or killed outright). Also, see Resistance.
The failure of cancer cells, viruses, or bacteria to respond to a drug used to kill or weaken them. The cells, viruses, or bacteria may be resistant to the drug at the beginning of treatment, or may become resistant after being exposed to the drug.
Drug resistance occurs when a virus changes in such a way that is is able to survive and multiply in the presence of the drugs that were designed to control it.
The ability of some disease-causing infectious agents, such as bacteria and viruses, to adapt themselves, grow, and multiply even in the presence of drugs that usually kill them. See Cross-Resistance.
The result of the cell's in our body not being able to resist the effects of a specific drug.
The result of cells' ability to resist the effects of a specific drug.
Drug resistance is the reduction in effectiveness of a drug in curing a disease or improving a patient's symptoms. When the drug is not intended to kill or inhibit a pathogen, then the term is equivalent to dosage failure or drug tolerance. More commonly, the term is used in the context of diseases caused by pathogens.
