1 Methicillin resistant Staphylococcus aureus in the critically ill
K.J. Hardy, P.M. Hawkey, F Gao, B.A. Oppenheim  British Journal of Anaesthesia  Volume 92, Issue 1, Pages (January 2004) DOI: /bja/aeh008 Copyright © 2004 British Journal of Anaesthesia Terms and Conditions

3 Fig 2 Action of β-lactam antibiotics on the peptidoglycan structure of the bacterial cell wall. (a) Cleavage of the peptide side chain releases the energy needed by transpeptidases to form the cross links of the peptidoglycan lattice. (b) Formation of the stable structure of the peptidoglycan lattice. (c) β-Lactams inactivate the PBPs and prevent the cleavage of the peptide side chain, and therefore prevent the release of energy and consequently cross linking. Results in a structure, which is lethal for cell growth. British Journal of Anaesthesia  , DOI: ( /bja/aeh008) Copyright © 2004 British Journal of Anaesthesia Terms and Conditions

5 Fig 4 MRSA acquisition and transmission between ICU, the hospital and the community. Patients are admitted to ICU colonized with MRSA, but a larger percentage of patients are transferred from ICU back to the general wards colonized with MRSA. This pattern is then continued out into the community. British Journal of Anaesthesia  , DOI: ( /bja/aeh008) Copyright © 2004 British Journal of Anaesthesia Terms and Conditions
