Abstract:
Antibiotic-associated diarrhea is a relatively common problem, and the main bacterial cause is Clostridioides difficile followed by Staphylococcus aureus and other pathogens. The diagnostic procedure for methicillin-resistant S. aureus enteritis is not well established. Phagocytosis is a key antimicrobial process involved in host defense. Phagocytosed bacteria identified by Gram staining are one marker to identify causative microorganisms and select subsequent treatment strategies. However, there are few reports on fecal Gram staining using phagocytosed bacteria as a target for diarrhea treatment. We report the successful use of fecal Gram staining to diagnose and treat methicillin-resistant S. aureus enteritis.
