Multidrug resistance

特許 係属中 Multiple drug resistance (MDR), multi-drug resistance or multiresistance is a condition enabling disease-causing microrganisms (bacteria, viruses, fungi or parasites) to resist distinct antimicrobials, first and foremost antibiotics,but also antifungal drugs, antiviral medications, antiparasitic drugs, chemicals of a wide variety[1] of structure and function targeted at eradicating the organism. Recognizing different degrees of MDR, the terms extensively-drug resistant (XDR) and pandrug-resistant (PDR) have been introduced. The definitions were published in 2011 in a journal called "Clinical Microbiology and Infection" and are openly accessible[2] This article discusses multi-drug resistance of bacteria, fungi, viruses and parasites, not that of tumor cells, which are discussed in the section of antineoplastic resistance.
