<p>Scientists at the S N Bose National Centre for Basic Sciences in Kolkata have found a method for early diagnosis of a peptic ulcer-causing bacteria with the help of a biomarker called 'BreathPrint' found in the breath, the Department of Science and Technology (DST) said on Saturday.</p>.<p>The team of researchers at the SNBNC, an institute under the DST, recently spotted the new biomarker for diagnosis of helicobacter pylori in semi-heavy water (HDO) in exhaled human breath.</p>.<p>The team used the study of different water molecular species in human breath, also called 'Breathomics' method, to explore different water isotopes in human exhaled breath, according to a DST statement.</p>.<p>The stomach infection cased by Helicobacter pylori may turn serious if it is not treated early. It is usually diagnosed by the traditional and panfully invasive endoscopy and biopsy tests which are not suitable for early diagnosis and follow up.</p>.<p>"Our gastrointestinal (GI) track plays a crucial role in water metabolism in the body.
