Clostridium difficile

Here's a trick if you are looking for C. difficile-related articles:

Ovid Medline:search: clostridium difficile
MeSH suggestions include:
exp Clostridium difficile/
exp Clostridium Infections/

Ovid EMBASE:
search: clostridium difficile
heading suggestion:
exp Clostridium difficile/

search: clostridium infections
heading suggestion:
exp Clostridium Infections/

So the heading: Clostridium Infections does exist but you'll only find it if you know where to look for it.

BTW, CINAHL(EBSCO version) returns the same headings as Ovid Medline.
