The respiratory system is responsible for gas exchange in animals-that is, the respiratory system transfers oxygen and carbon dioxide from the air to the circulatory system, and vice versa, across the respiratory surface. Different organisms utilize different methods of respiration.
Vancomycin is a branched tricyclic glycosylated peptide with bactericidal activity against most organisms and bacteriostatic effect on enterococci.
The studies included 2655 adults who were receiving standard-of-care oral antibiotics (vancomycin, metronidazole, or fidaxomicin) for C difficile infection. Researchers randomly assigned patients to an infusion of bezlotoxumab (10 mg/kg), actoxumab plus bezlotoxumab (10 mg/kg each), or placebo (0.9% saline).
