Antifungal drug resistance evoked through RNAi-dependent epimutations Long lasting mutations were once thought to be the only way for drug-resistant strains to evolve Microorganisms like bacteria and fungi can evade treatment by acquiring mutations in the genes targeted by antibiotics or antifungal medicines. These permanent mutations were once thought to be the only way for drug-resistant strains to evolve. Now a new study has shown that microorganisms may use a short-term silencing of drug targets – – known as epimutations – – to gain the advantages of drug resistance without the commitment ?complete erection . Although new mechanism was uncovered in a fungus known as Mucor circinelloides, chances are to be employed by other fungi in addition to bacteria, viruses and other organisms to endure treatment with numerous drugs.

These drugs are commonly found in elderly patients to treat illnesses such as for example irritable bowel syndrome, urinary incontinence, and Parkinson’s disease, so that it is essential that doctors know about this effect, say the experts.
