A cute blog called Adopt a Microbe by Emma Lurie features bacteria as cuddly little cartoons. This one, is heliobacter pylori, or H. pylori, the cause of gastrointestinal ulcers in A LOT of people.
You can call me H. pylori.
I am a helical Gram Negative rod.
I live in the mucous layer of the stomach.
I am famous for causing duodenal and gastric ulcers by making the stomach secrete lots of acid.
I am also a risk factor to some gastric cancers.
More than half the people in the world have me.
In 2005 two scientists from Perth, Western Australia - Robin Warren and Barry Marshall - were given a Nobel prize for their work with me.
Marshall even drank a dish full of me to give himself stomach ulcers and prove their theories.
Before that, everyone thought stomach ulcers were caused by stress!
