Glossarium

Antimicrobial resistance is observed when the minimum inhibitory concentration value of an antimicrobial is equal to or above its resistance breakpoint. Resistant bacteria are able to withstand the effects of an antimicrobial drug using principally one of these four mechanisms: 1) drug inactivation or modification by enzyme production, 2) adaptation of its metabolism, 3) structural modification of antimicrobial targets and, 4) mechanisms to decrease drug permeability or increase drug elimination. Moreover, some bacteria display natural (or intrinsic) resistance to certain antimicrobials. CIPARS (2005)

Is the result of microbes changing in ways which diminish or inhibit the effectiveness of drugs or chemicals used to cure or prevent infections. CVMA (2008)

A property of bacteria that confers the capacity to inactivate or exclude antibiotics or a mechanism that blocks the inhibitory or killing effects of antibiotics. Or the ability of bacteria to resist or overcome the deleterious effects of an antibiotic. CVMA (PUGS 2008)

A property of bacteria that confers the capacity to inactivate or exclude antibiotics (antimicrobial) or a mechanism that blocks the inhibitory or killing effects of antibiotics. Or the ability of bacteria to resist or overcome the deleterious effects of an antibiotic. CVMA (PUGS 2008)
