Look At Methicillin Resistant (S. Aureus (MRSA)

Methicillin Resistant Staphylococcus Aureus (MRSA) was first discovered as the superbug in the United Kingdom in 1961 and because of its nature of resisting antibiotic treatments, it was difficult to treat this bacterium (Sanders, 2012). Staphylococcus Aureus (S. Aureus) is one of the normal floras that make ecological niches on certain body parts but usually on the anterior nares. It is a commensal organism that can also be pathogenic if its ecological niches’ such as body’s defense system (skin, mucosal layers) is being damaged by any invasive external force where it can be introduced into the body tissues. S. Aureus forms biofilms on the hosts’ defense surfaces making it able to persist in its course of actions and evade the hosts’ antimicrobial …show more content…
Attached to each acid residue is a stem peptide. The β-lactam type of antibiotics resemble the terminal bond of this stem peptide, where in normal process, it interferes with the cross-linking reaction of the staphylococcus wall and the host’s surface. However, the main mechanism of methicillin resistance in S. Aureus is from the expression of a foreign penicillin binding proteins by its wall that takes over the cross-linking reactions of the host’s penicillin binding proteins thus resist the action of methicillin medicines. Furthermore, according to McKenzie, Pinger, & Kotecki (2005), the chain of MRSA infections is the secret and most effective way that this infectious pathogen is able to survive around while infecting others in the hospital setting. It occurs in a sequence of process where six cornerstones are linked together by strong connections in order for this agent to survive. However, these cornerstones include the MRSA agent, a reservoir, and mode of escape, mode of transfer, a mode of entry and the susceptible host. The rule of this chain is that no infection can continue if the connections of these chains are
