简要总结
The investigators hypothesis is that daily use of a proton pump inhibitor (PPI) is associated with significant alterations in the healthy fecal microbiome that are similar to those seen in persons with an initial episode of clostridium difficile infection (CDI).

研究组 & 干预措施
Proton pump inhibitor
We will recruit 10 healthy adult individuals and 5 adult patients with an initial episode of CDI cared for at Mayo Clinic in Arizona. A baseline stool sample will be collected from the healthy individuals. They will then be given a PPI, omeprazole 20 mg, to be taken once (n=5) or twice (n=5) daily for 1 month. Stool samples will be collected after 1 week and again after 1 month. A final stool sample will be collected 1 month after stopping the omeprazole.
A stool sample will be collected from the CDI subjects before treatment of the infection and again 2 months after treatment to avoid enrolling those at risk for relapse (which most commonly occurs during the first 2 months after treatment).
干预措施: omeprazole (Drug)
