Overview
S. aureus Intestinal Colonization
Human intestine is a highly complex microbial ecosystem. It accommodates commensal microflora species, various types of secretory fluids, fermentation metabolites and host defense molecules that promote colonization resistance to pathogenic bacteria. However, Staphylococcus aureus, one of the most opportunistic and invasive pathogens, is capable of disrupting this colonization resistance and infecting the intestine. Patients with S. aureus intestinal colonization suffer from fecal incontinence, diarrhea, pseudomembranous colitis and so on.
