One of the most worrisome characteristics of p aeruginosa is its low antibiotic susceptibility, which is attributable to a concerted action of multidrug efflux pumps with chromosomally encoded antibiotic resistance genes (eg, mexab-oprm, mexxy) and the low permeability of the bacterial cellular envelopes. Antimicrobial resistance is the ability of microorganisms (such as bacteria, fungi, viruses, or protozoa) to nullify the effects of antimicrobial drugs, resulting in these drugs becoming ineffective 1,2 amr can affect anyone, of any age, in any country.

Antimicrobial resistance (amr or ar) is the ability of a microbe to resist the effects of medication that once could successfully treat the microbe the term antibiotic resistance (ar or abr) is a subset of amr, as it applies only to bacteria becoming resistant to antibiotics.
