this is amazing. Clostridium difficile is a very dangerous bacteria that is really resistant to antibiotics, I think mostly everybody has it living in their colon but our body's competing bacteria keep it under control. A lot of people in America get it from using wide spectrum antibiotics, for example amoxcillin, which kills a lot of the "good" bacteria in your colon, leaving Clostridium difficile to take over and wreak havoc. You'll know you have it if during or after taking antibiotics you start to get constant diarrhea that gets progressively worse.
