Sir,
During the past two decades Gram-positive bacteria, predominantly staphylococci and streptococci, have re-emerged as important pathogens. Staphylococci, in particular, have demonstrated a remarkable propensity for acquiring mechanisms of resistance to every new antimicrobial to become available and for spreading among patients, institutions and communities. More recently, there have also been increasing concerns about ß-lactam resistance in Streptococcus pneumoniae and other streptococci. Clearly, there is a pressing need to identify novel compounds that can be used as therapy for patients with infections caused by these organisms.1
Quinupristin/dalfopristin, a combination of two streptogramins, is one such agent. It has been
shown to have excellent activity in vitro against a broad range of staphylococci
