Abstract:

Background

Staphylococcus aureus is a common pathogenic commensal bacterium. It is estimated that one in three healthy people carry this type of bacteria on their skin, nose, or mouth as normal flora. However, within the hospital environment this, colonization with this microorganisms can lead to serious consequences as in a potentially patients, visitors and staff whose they can act as a reservoir and source for spreading of infection to the susceptible individuals. Most Staphylococcus aureus bacteria can be treated with methicillin- type antibiotics. However, certain type of this bacteria are resistant to this antibiotics. This group of microorganism is called MRSA bacteria

Aim of the Study; To determine the prevalence of methicillin resistant Staphylococcus aureus MRSA and their antimicrobial susceptibility patterns among clinical samples. Materials and Methods; Out of sixty three participants subjected to this study, a total of twenty clinical samples were identified as infected with S. aureus. The sensitivity patterns of these isolates samples were determined by using the Kirby-Bauer disk diffusion method. Results : The prevalence of MRSA among the group studded was 15%. Nine MRSA were isolated from ear specimens ( 22.2%), and eight wereisolates from pus specimens ( 12.5%).Conclusion; The prevalence of MRSA in this study was highly, emphasizing the need for local or country-based surveillance to

characterize and monitor MRSA and to develop strategies that will improve MRSA treatment and control.
