The agr locus is important for virulence in a variety of animal models of infection, and has been assumed by inference to have a major role in human infection. The effector molecule of the agr system is a regulatory RNA, called RNAIII, whose synthesis is dependent on agr activation and driven by the P3 promoter of the agr system, RNAIII inhibiting peptide (RIP), is very effective in treating severe polymicrobial infections, including drug-resistant staphylococci like MRSA, since RIP downregulates the expression of genes involved in biofilm formation and toxin production, and upregulates genes involved in stress response.The fact that determining virulence genes may help to differentiate no infected from infected wound is an attractive previous result since the virulence genes of S. aureus were present significantly more in wound with grades 2-4 ulcers than grade I. So we will explore in the paper the virulence profile, the presence and functions of agr locus, clarify a possible relation between agr groups and wound grading in cases presented with diabetic foot ulcers in our locality.
