Scientists have identified Helico-
bacter pylori, a bacteria that causes
stomach ulcers, in contaminated
water, thus giving a clue to the
source of infection.

Preliminary results of studies conducted by Massachusetts Institute of Technology scientists have shown the presence of the bacteria in a water sample from Narino, Columbia where ulcer infections are common.
