A bacteria that could cause stomach cancer in adults may protect children from developing asthma,according to a study.
The bacterium Helicobacter pylori has co-existed with the humans for at least 50,000 years and can lead to peptic ulcers and stomach cancer.
However,kids between ages of 3 and 13 are nearly 59 percent less likely to have asthma if they carry the bacterium,according to the study among 7000 subjects led by New York University School of Medicine.
