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-resistant Enterococci (VRE). Enterococci are a group of bacteria naturally found in the intestines of humans and other animals. Vancomycin-resistant enterococci (VRE) are a group of bacteria that are resistant to vancomycin, an antibiotic commonly used to treat drug-resistant bacteria.hen bacteria do make us sick, antibiotics are usually available to treat the illness. However, over time, bacteria develop resistance to some types of antibiotics. This means that the drugs are no longer effective at killing the bacteria and the infections become harder to treat.
