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.
Like MRSA, Vancomycin-intermediate Staphylococcus aureus (VISA) and Vancomycin-resistantStaphylococcus aureus (VRSA) are types of staph bacteria that are resistant (or have intermediate resistance) to certain antibiotics. Because of their resistance to antibiotics, VISA/VRSA infections can be more difficult to treat.
