Background:
Staphylococcus aureus is one of the important human pathogens which are mainly isolated from wound, skin and contaminated respiratory excretions. Because many of hospital staff and patients carry this pathogen in their nose or skin, close contacts and touching have special role in spreading the infection in hospitals. Also, antibiotic resistant S. aureus, especially Methicillin Resistant S. ?ureus (MRSA) have been seen among subjects. Thus, there should be an investigation for Bacteria colonization in nose of hospital staff and patients. Furthermore, investigation of antibiotic resistance pattern and examination of genotyping properties of resistant strains have a high efficacy in control and recognition of infection origin.
