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.
Oral vancomycin is a glycopeptide antibiotic that is used for the treatment of Clostridium difficile diarrhea and staphylococcal enterocolitis.
