Streptogramin

Class of natural cyclic peptide antibiotics produced by certain subspecies of Streptomyces

Streptogramins are a class of antibiotics.[1]

Streptogramins are effective in the treatment of vancomycin-resistant Staphylococcus aureus (VRSA) and vancomycin-resistant Enterococcus (VRE), two of the most rapidly growing strains of multidrug-resistant bacteria. They fall into two groups: streptogramin A and streptogramin B.[citation needed]

Members include:

  • Quinupristin/dalfopristin
  • Pristinamycin
  • Virginiamycin
  • NXL 103, an experimental streptogramin in clinical trials for the treatment of respiratory tract infections.[2]
