The thermoregularoty reflex then initiates the mechanism to raise core temperature and results in pyrexia (Tortora and Grabowski 1996).
ii) Predisposing factors that make the host susceptible to MRSA
The S aureus organism can be found naturally on 50% of the population maintains Alexander et al (2000). MRSA colonises on areas of the skin, but only becomes infectious when immunity is compromised and integrity is lost. Nursing Times (2003a) states MRSA is unlikely to develop into an infection in a healthy individual. However according to Hosein et al (2002) the outcome in the
