Quizplus · Accepted Answer

Members of the genus Pseudomonas are known to be most resistant to quaternary ammonium compounds. This is because they have an efflux pump system that can remove the compounds from their cells, making them less effective as disinfectants. Gram-positive bacteria, members of the genus Staphylococcus, fungi, and enveloped viruses are generally more susceptible to quaternary ammonium compounds compared to Pseudomonas.
