¶ … hospitals is the spread of MRSA (staphylococcus aureus). This pathogen remains a leading cause of hospital-acquired infection. Current 'typing' methods for the genome to identify the pathogen include "phage typing, multi-locus sequence typing (MLST) and pulsed-field gel electrophoresis (PFGE)" but these methods "have serious limitations when used to investigate the finer details of infection outbreaks" (Price et al. 2013: 14). This is why the use of whole genome sequencing that allows scientists to create distinctions up to a single nucleotide is useful. Whole genome sequences can be used to classify and characterize genetic differences in a far more refined fashion than previous methods "and additionally provides information about the genetic basis of phenotypic characteristics, including antibiotic susceptibility and virulence" (Price et al. 2013: 14). Local-level awareness of the history of disease transmission allows a more carefully matched protocol for treatment as well as improves tracking. "Combined with epidemiological data, such as information on dates of admission to hospital, it is then possible to draw inferences about the probability that a transmission event occurred or not, with sufficient accuracy to direct better targeting of infection control resources" (Price et al. 2013: 19). Human genome sequencing also provides potential clues as to why...

Also, experiments regarding the pathogen can reveal methodologies of transmission, such as its ability to invade and proliferate within osteoblasts or how certain factors can enhance the growth and spread of MRSA.
Key issues in disease control

Given that staphylococcus aureus is not well-suited to vaccine development, instituting proper protocols regarding disease containment is essential and is likely to remain important in the future in containing the spread of illnesses caused by the pathogen. Proper hand-washing and containment of infected patients is vital. There are also distinct strains of staphylococcus aureus with various degrees of virulence that demand different treatment protocols. For example, in Blot (et al. 2002) a comparisons between patients with bacteremia involving methicillin-susceptible (MSSA) and methicillin-resistant (MRSA) S. aureus found that patients with MRSA had much higher mortality rates. "MRSA bacteremia had more acute renal failure and hemodynamic instability than patients with MSSA bacteremia. They had a longer intensive care unit stay and ventilator dependency. Patients with MRSA bacteremia had a higher 30-day mortality rate" (Blot et al. 2002: 229). Not all strains are created equal, once again underlining the need for proper whole genome coding to understand…
