The Guy
Barry Marshall was born in Kalgoorlie, Western Australia, in 1951. He was the eldest of four kids. His dad did a variety of things to make a living, and his mom was a nurse. When he came of age, Marshall attended the University of Western Australia School of Medicine.
While Registrar in Medicine at Royal Perth Hospital, Marshall and a fellow research physician, Dr. Robin Warren, began studying the gut microbiome.
Curiously, there are more bacteria in and on your body than there are cells. That means when you look at someone, there is actually more stuff that’s not them than is them. That applies to dirty farmers, adorable little infants, and even pretty girls. That’s kind of creepy if you let yourself think about it.
Drs. Marshall and Warren observed that a lot of people with gastritis, stomach ulcers and gastric cancer tended to have spiral bacteria in their stomachs.
Eventually, they cultured Helicobacter pylori and suspected that particular microscopic beastie to be the culprit. When they announced their suppositions, they were laughed out of the scientific circles.
Their paper on the subject, presented to the Gastroenterological Society of Australia, was rated in the bottom 10% of submissions in 1983. After all, everybody knew that gastric ulcers were caused by spicy foods and high-stress jobs. Marshall later said, “Everyone was against me, but I knew I was right.”
There was reason to be skeptical. The first 30 of 100 gastric samples that the men harvested did not culture out H. pylori. However, Marshall later discovered that the lab techs were discarding the cultures at the two-day mark, which is customary. H. pylori takes longer than that to grow. Warren and Marshall believed they were on to something.
