The main mechanisms of resistance include limiting uptake of a drug, modification of a drug target, inactivation of a drug, and active efflux of a drug. These mechanisms may be native to the microorganisms, or acquired from other microorganisms. What is the term used for the genes that are naturally occurring in the bacteria, but are only expressed to resistance levels after exposure to an antibiotic?

<p>induced</p> Signup and view all the answers

Persistence is undoubtedly due to the fact that some cells in a bacterial population may be in stationary growth phase (dormant). Most antimicrobial agents have no effect on cells that are not actively growing and dividing. Persister cells occur at a rate of around 1% in a culture that is in stationary phase. What is the term used for a trait that is shared universally within a bacterial species independent of previous antibiotic exposure?

<p>Intrinsic resistance</p> Signup and view all the answers

The most common bacterial mechanisms involved in intrinsic resistance include reduced permeability of the outer membrane (most specifically the lipopolysaccharide, LPS, in gram-negative bacteria) and the natural activity of efflux pumps. Although multidrug efflux pumps are also a common mechanism of induced resistance, what is the term used for a trait that is not related to horizontal gene transfer?

______ involves the acquisition of genetic material that confers resistance. This can be possible through all of the main routes by which bacteria acquire any genetic material: transformation, transposition, and conjugation. What is the term used for the acquisition of genetic material that may be temporary or permanent?
