Which of the following antibiotics does NOT cover pseudomonas?

ErtaPenem is the antibiotic that does not cover Pseudomonas aeruginosa. While imipenem, meropenem, and cefepime are all known to have activity against Pseudomonas, ertapenem has a more limited spectrum of activity.

ErtaPenem is a carbapenem antibiotic that is often utilized for its efficacy against various Gram-positive and Gram-negative bacteria, but it specifically lacks activity against Pseudomonas and Acinetobacter species. This absence of coverage is an important consideration when choosing antibiotics, especially in a setting where infections due to Pseudomonas are suspected or confirmed.

In contrast, imipenem and meropenem are broad-spectrum antibiotics that are effective against Pseudomonas due to their stability against a variety of beta-lactamases and their ability to penetrate bacterial cell walls. Cefepime, a fourth-generation cephalosporin, is also effective against Pseudomonas due to its robust activity against a range of bacteria, including resistant strains.

Understanding the specific coverage profiles of antibiotics is crucial in clinical decision-making, ensuring that the selected antibiotic adequately targets the suspected pathogens while minimizing resistance risks.
