CONSIDERING that the majority of human beings have had Helicobacter pylori living in their stomachs most of their lives, it is hardly surprising that this spiral-shaped bacteria has been spotted by scientists long before Australian pathologist and Nobel laureate Prof Emeritus Dr Robin Warren first noticed them in gastric biopsies of patients with gastritis in 1979.
Among the first to report seeing the bacteria in sections of the stomach was noted German-Swiss pathologist Edwin Klebs, who also identified the bacteria that causes diphtheria, and has the bacteria genus Klebsiella named after him.
