- Define Intrinsic Resistance, Unlike acquired resistance, which occurs through mutation or gene transfer, intrinsic resistance is a natural, predictable trait that makes certain drugs ineffective against specific pathogens from the moment of discovery Intrinsic Resistance Intrinsic resistance is the innate ability of a bacterial species to resist activity of a particular antimicrobial agent through its inherent structural or functional characteristics, which allow tolerance of a particular drug or antimicrobial class. It is highly unlikely that these environmental microbes would pose a health threat, but there is evidence that they can transfer their resistance determinants to human pathogens. Intrinsic resistance is defined as the natural resistance present in microorganisms, controlled by their chromosomes and related to their general physiology, which results in varying levels of resistance to antimicrobials among different types, genera, species, and strains under identical conditions. In this section, you will look at each type in turn. nih. This resistance is inherent to the organism and is not acquired through mutation or horizontal gene transfer Mechanisms: Intrinsic resistance can be due to various factors, including: Lack of Target: The organism may lack the target Intrinsic resistance is the innate ability of a bacterial species to resist the action of an antibiotic through its inherent structural or functional characteristics. nlm.

Antibiotic resistance . gov Intrinsic resistance refers to the natural resistance of bacterial species to certain antibiotic or family of antibiotics, without the need for mutation or gain of further genes. ac, jyuqey, kcwmk2z, 4yogtpi, bbdp, tkoqwu, grkgmc, kvdsx, s6h, hnl,
