The development and use of a test to identify resistance to the anticoagulant difenacoum in the Norway rat (Rattus norvegicus). 1978

R Redfern, and J E Gill

Feeding tests were carried out in the laboratory to obtain basic data on the susceptibility of wild Norway rats to difenacoum. The results were used to derive a standard test procedure for the identification of difenacoum resistance in warfarin-susceptible and resistant rats. Details are given of tests on rats from suspected difenacoum-resistant infestations on farms.

UI	MeSH Term	Description	Entries
D004361	Drug Tolerance	Progressive diminution of the susceptibility of a human or animal to the effects of a drug, resulting from its continued administration. It should be differentiated from DRUG RESISTANCE wherein an organism, disease, or tissue fails to respond to the intended effectiveness of a chemical or drug. It should also be differentiated from MAXIMUM TOLERATED DOSE and NO-OBSERVED-ADVERSE-EFFECT LEVEL.	Drug Tolerances,Tolerance, Drug,Tolerances, Drug
D004739	England	A part of Great Britain within the United Kingdom.
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012375	Rodent Control	The reduction or regulation of the population of noxious, destructive, or dangerous rodents through chemical, biological, or other means.	Control, Rodent
D012378	Rodenticides	Substances used to destroy or inhibit the action of rats, mice, or other rodents.	Rodenticide
D014859	Warfarin	An anticoagulant that acts by inhibiting the synthesis of vitamin K-dependent coagulation factors. Warfarin is indicated for the prophylaxis and/or treatment of venous thrombosis and its extension, pulmonary embolism, and atrial fibrillation with embolization. It is also used as an adjunct in the prophylaxis of systemic embolism after myocardial infarction. Warfarin is also used as a rodenticide.	4-Hydroxy-3-(3-oxo-1-phenylbutyl)-2H-1-benzopyran-2-one,Aldocumar,Apo-Warfarin,Coumadin,Coumadine,Gen-Warfarin,Marevan,Tedicumar,Warfant,Warfarin Potassium,Warfarin Sodium,Potassium, Warfarin,Sodium, Warfarin
D015110	4-Hydroxycoumarins	Substances found in many plants, containing the 4-hydroxycoumarin radical. They interfere with vitamin K and the blood clotting mechanism, are tightly protein-bound, inhibit mitochondrial and microsomal enzymes, and are used as oral anticoagulants.	4 Hydroxycoumarins
