Question

74) Pseudomonas aeruginosa is one of the most notorio mechanisms does this bacteria use to evade antimicrobials? A) target alterations B) drug inactivation C) efflux pumps that pump the drugs out of the bacterial cell D) reduced permeability E) This bacteria uses all of the possible ways to evade antimicrobials, which is why it is so good at it. usly resistant pathogens. Which of the following

Answer 1

74.

Pseudomonas aeruginosa is a bacteria that resist to the many of the antibiotics.

Pseudomonas excludes the most of the antimicrobials out of the cell.

This exclusion makes the cell impermeable to the drug. This impermeability protects the bacteria from drug.

MexAB-OprM pump system that removes β-lactams, chloramphenicol, fluoroquinolones, macrolides, novobiocin, sulfonamides, tetracycline, and trimethoprim, as well as various dyes and detergents

The natural role of MexAB-OprM may be to remove amphipathic permeants, which otherwise would disorganize the cytoplasmic membrane.

So that answer is

E. This bacteria uses all of the possible ways to evade antimicrobials, which why it is so good at it.
