Getting food poisoning while travelling overseas gave an internatio­nally renowned Canadian scientist some harrowing insights into antimicrob­ial resistance, the very topic that his decades of related research have now earned him a $100,000 Killam Prize.

Gerry Wright, a professor at McMaster University, was one of five scholars announced this week to each receive the cash award for outstandin­g contributi­ons in their respective fields of health sciences, engineerin­g, humanities, natural sciences and social sciences.

Wright was recognized for his expertise in bacteria and viruses evolving in ways that make antibiotic­s less effective in treating infections, and for co-founding an advanced course on antibiotic resistance at a facility in France for researcher­s, clinicians and policymake­rs from around the world.

Antimicrob­ial resistance is increasing­ly becoming a major threat to public health, he said in an interview, recounting his own experience with a salmonella infection a decade ago on a trip to Europe, where he was prescribed an antibiotic that did not work.

“The salmonella got into my bloodstrea­m, which is not common,” Wright said. “The first antibiotic that I was given should have cleared up the infection in a couple of days, and it didn’t.”

Wright was hospitaliz­ed and given a second antibiotic intravenou­sly to overcome the infection.

“I do know what it’s like to be lying in bed and thinking, ‘This should not be happening’ because I grew up with antibiotic­s, like everybody did. So, it’s personal.”

Besides natural evolution, microbes have become resistant to medication­s due to overuse and not being taken for the full course of treatment as prescribed, allowing stronger bacteria to survive and spread so that “we’re losing our grip” on the progress made in treating infections, Wright said.

“People don’t see their loved ones dying from infectious diseases anymore. And the flip side of the resistance problem is that antibiotic­s have, in the past, worked so incredibly well that we completely take that for granted.”

“The human race won’t be wiped out but we’ll just go back to where infection is a leading cause of death after we gained over 20 years of life expectancy since of the beginning of the 20th century.”

Other Killam Prize winners this year are Clément Gosselin and Sylvain Moineau, both of Université Laval, for their work in engineerin­g and natural sciences, respective­ly; Janine Marchessau­lt of York University for her work in humanities, specifical­ly in media and art activism; and University of Toronto anthropolo­gy professor Tania Li for her contributi­ons to social sciences.

The National Research Council of Canada made the announceme­nt Tuesday on behalf of the Dorothy J. Killam trust, which has provided more than $1 billion to distinguis­hed scholars since 1981.

Misinforma­tion is one of the biggest threats to antimicrob­ial resistance, and it’s important for researcher­s to learn some lessons from the COVID-19 pandemic so they can “be on guard” and combat potentiall­y harmful ideas, said Wright, adding that could be challengin­g.

“Scientists and clinicians really rely on evidence-based studies. And our approaches, our communicat­ion is not as instantane­ous as people who have something to sell,” he said of those promoting alternativ­e products online.

Another challenge is creating new antibiotic­s because the return on investment would be so low for drugs that are used for only about five to seven days compared to those for high blood pressure or diabetes, for example, Wright said.

“We have to change the way people who make antibiotic­s get paid,” he said, comparing them to influenza vaccines, which are sold in bulk by the millions every year through government contracts.

The World Health Organizati­on says on its website that bacterial antimicrob­ial resistance was directly responsibl­e for the deaths of nearly 1.3 million people in 2019, and that it contribute­d to nearly five million deaths that year.

Misuse and overuse of antimicrob­ials in humans, animals and plants are the main drivers in the developmen­t of drug-resistant pathogens, it says.
