streptogramin

(strĕp-tō-gram'in),
A synthetic protein that breaks down DNA, used to thin out the pulmonary secretions of patients with cystic fibrosis.

strep·to·gra·min

(strep'tō-gram'in)
A mixture of two structurally distinct compounds, type A and type B, which act at the level of inhibition of translation through binding to the bacterial ribosome; separately bacteriostatic but bactericidal in appropriate ratios. Antibiotics quinupristin and dalfopristin are both streptogramins.

streptogramin

(strĕp″tō-grăm′ĭn)
Any of a class of antibiotics effective against gram-positive bacteria that bind to the bacterial ribosome and inhibit protein synthesis. An example is the combination antibiotic quinupristin-dalfopristin.

Antibiotic-resistant enterococci are the leading causes of hospital-acquired infections of bloodstream and urinary tract since 1980s.10 Three main reasons behind this multidrug-resistant enterococci emergence include intrinsic resistance to antimicrobial agents like beta-lactams and aminoglycosides, and acquired resistance through mobile elements like transposon and plasmids against glycopeptides, quinolones, tetracyclines, macrolides and streptogramin or through the horizontal transfer of resistance genes.11
However, resistance to erythromycin (a macrolide) is usually associated with resistance to clindamycin (a lincosamide) and to type B streptogramin, and this cross-resistance is normally mediated by the erythromycin ribosomal methylase (erm) genes.
