Tropheryma whippelei

Hello.
My name is T. whippelei.
I'm very mysterious, I don't tell anyone how I get into people.
I'm also very rare.
I like infecting older men.

I mostly infect your intestines.
When I'm there, I stop you getting nutrients from food.
You get fever, weight loss, diarrhoea and cramps.
I also get into the rest of your body, into your heart, lungs, skin, and nerves.
