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 example of a glycopeptide antibiotic. It works as an antibiotic by inhibiting cell wall synthesis via the mechanism of peptidoglycan inhibition. Peptidoglycan is a key component of the bacterial cell wall and without it, the cell wall is not able to function and lyses; therefore vancomycin is classed as bactericidal.
