Pseudomonas aeruginosa è un piccolo batterio a forma di bastoncello (lunghezza di 1,5 – 3 µm e larghezza compresa tra 0,5 e 0,8 µm).

Le colture microbiologiche possono essere coltivate su piastre di Petri di varie dimensioni.

    Does Unasyn cover Pseudomonas?

    The question comes up because so many people reflexively reach for “vanc-zosyn” for broad coverage. The answer is Pseudomonas. The more difficult question is what additional coverage is gained with ampicillin-sulbactam over piperacillin-tazobactam. The answer is acinetobacter. The additional coverage comes from the the sulbactam portion.
