How does quinupristin-dalfopristin work to treat bacterial infections?

Quinupristin-dalfopristin (brand name Synercid) is known as a streptogramin antibiotic. As its name suggests, quinupristin-dalfopristin is a combination of two different antibiotics: quinupristin and dalfopristin. Each of these antibiotics attaches to a specific structure within the bacterial cell, called a ribosome. Quinupristin attaches to one part of the ribosome, while dalfopristin attaches to another part. The combination of the two antibiotics is a powerful one: as individual antibiotics, each drug would be able to stop but not kill the bacteria. By working together, however, the combination antibiotic is able to kill the bacteria that is causing a serious infection.
