A bacteria found in the gut or intestines, often responsible for food poisoning.
? Campilobacta ? Spelling is phonetic and not correct. Do you have the exact name?

I am certain that you're thinking of campylobacter.

"When it comes to food poisoning, big outbreaks make headlines. E.
coli in apple juice and alfalfa sprouts. Listeria in cheese and hot
dogs. Salmonella in eggs and on poultry. But the most frequently
diagnosed food-borne bacterium rarely makes the news. The name of the
unsung bug? Campylobacter."
