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.
Examples for bactericidal antibiotics include; penicillin derivatives, cephalosporins, monobactams, and vancomycin. In addition, aminoglycosidic antibiotics are also considered as bactericidal, but they may also be bacteriostatic for some infections.The minimum concentration of a drug that is needed to kill a certain strain of bacteria is called the âminimum bactericidal concentrationâ or MBC.xamples for bactericidal antibiotics include; penicillin derivatives, cephalosporins, monobactams, and vancomycin. In addition, aminoglycosidic antibiotics are also considered as bactericidal, but they may also be bacteriostatic for some infections.
