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.
Vancomycin is an inhibitor of cell wall synthesis and is bactericidal for gram positive organisms. Antibiotics exert their effects via five basic mechanisms: (1) Inhibition of cell wall synthesis (cephalosporins, penicillins, vancomycin, imipenem). (2) Increasing cell membrane permeability (Bacitracin). (3) Ribosomal inhibition (gentamycin, erythromycins, linezolid, tetracyclines).
