Say it like this: klos-TRID-ee-um DIF-ih-seel in-FEK-shun. The stress (loudest part) falls on the second syllable of Clostridium (TRID) and the first syllable of difficile (DIF). The whole phrase takes practice, but breaking it into three separate words makes it easier.
What's the correct way to say the first word, Clostridium?

Pronounce it: klos-TRID-ee-um. It has four syllables: KLOS-TRID-ee-um. The stress goes on the second syllable (TRID), not the first. A common mistake is stressing the first syllable (KLOS), which sounds wrong.

What do the word parts of Clostridium mean?

Clostridium comes from Greek and Latin roots: "closter" means spindle or closed, and "idium" is a scientific suffix for a small organism. The name refers to the bacteria's spindle-like shape when it forms protective spores.

What does difficile mean in plain English?

Difficile is a Latin word meaning "difficult" or "hard to treat." The bacteria earned this name because it's hard to get rid of and resists treatment, not because it's hard to pronounce!
