What are streptogramins used to treat?

Streptogramins are a class of antibiotics. 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.

Is Streptogramin bactericidal?

The streptogramins consist of mixtures of two structurally distinct compounds, type A and type B, which are separately bacteriostatic, but bactericidal in appropriate ratios. These antibiotics act at the level of inhibition of translation through binding to the bacterial ribosome.

What are Ketolides used for?

Ketolides (telithromycin) are derivatives of erythromycin A specifically designed for activity against bacteria responsible for community-acquired respiratory tract infections. Telithromycin is a 14-membered macrolide with a 3-keto group substitution.

How do cephalosporins work?

Cephalosporins are bactericidal (kill bacteria) and work in a similar way to penicillins. They bind to and block the activity of enzymes responsible for making peptidoglycan, an important component of the bacterial cell wall.

How does Streptogramin A and B work?

Streptogramins A and B synergically inhibit cell growth of gram positive, less so gram negative bacteria by inhibiting protein synthesis, but separately they are bacteriostatic. The molecular target of streptogramins is the 23S rRNA. Both streptogramin A and B bind to the P binding site of the 50S ribosome subunit.

Is streptogramins broad spectrum?

The combination has a broad spectrum of activity against Gram-positive bacteria, including multidrug resistant bacilli. A comprehensive review has been published [3].

How long does teicoplanin take to work?

Teicoplanin should be administered by the intravenous or intramuscular route. The intravenous injection may be administered either as a bolus over 3 to 5 minutes or as a 30-minute infusion….Other bacteria.

How do Lipopeptides work?

Lipopeptides exert their effect by binding and disrupting the cell membrane integrity of the target bacteria and initiating a series of events that eventually leads to cell death.
