Hello and thanks for posting. Sorry to hear about your friend. As far as the infection is concerned, we do not always have the answers why certain infections are found in the intestinal tract. There are many reasons (one of them certainly being in hospitals as you have eluded to). Since you state that he is still having problems with the staph infection, please make sure this gets addressed this week to eradicate and sometimes you can also recommended a probiotic which provides beneficial bacteria to help balance the microbial population in the gut after the acute infection has been successfully treated.
Best of luck to your friend.
