Human-bacterial symbiosis?

Post by Ultrashogun » Wed Jan 04, 2006 6:13 am

Formally the relationship between humans and the bacteria in our intestines is a symbiosis, but I never read about it mentioned in this way, is it one, or not?

yes, it's a symbiosis. E.coli uses the digested food to muliply itself, but it thereby produces vitamin K for the organism. So it's a mutualism.
