- This agent has activity against antibiotic-resistant gram-positive organisms, especially VRE, MRSA, and antibiotic-resistant strains of Streptococcus pneumoniae. It has some activity against gram-negative upper respiratory pathogens (Haemophilus and Moraxella) and anaerobes, but more appropriate antibiotics are available to treat these infections. Quinupristin/dalfopristin is bacteriostatic for enterococci and can be used for treatment of serious infections with VRE (only E. faecium because it is inactive against E. faecalis).
