I don’t know about you, but the last two winters where I live have been plagued by extreme flu seasons, with scores of friends and coworkers complaining about getting sicker than they had in ages. Now that it’s summer, I don’t want to think about the hacking and nose-blowing of winter, but a lot of people have started asking an important question: are pathogens getting stronger?
Statistically, we know that many infections have become resistant to drugs. Between overused antibiotics and America’s obsession with antibacterial hand gel, we have created an evolutionary arms races that’s produced super bugs and drug-resistant strains. Some experts fear that resistant infections could kill 10 million people a year by 2050. Fortunately, scientists are out there fortifying our defenses. At The Atlantic, Maryn McKenna writes about the scientist who revived a largely abandoned technique: collecting germs from filthy places. Gathering samples from everything from train station handrails to dog dishes to the bottom of peoples’ shoes, Adam Roberts believes that the answers to our global resistance problem lies not simply in gene-research, but in what’s called the natural microbial world, which is were our first antibiotics came from.
He decided to start where pharmaceutical chemistry had left off decades earlier: in the messy real-world settings where bacteria duke it out. He launched his campaign, called Swab and Send, in February 2015. For £5, participants got a sample tube, a mailing envelope, and an explanation of what Roberts wanted them to look for: a spot in the environment where bacteria were likely to be competing for nutrition and room to reproduce. He asked them to use their imagination. The less sanitary, the better.
In a departure from the first antibiotic searches, Roberts does not ask his sample-collectors to focus on soil. Instead he wants them to search in places his predecessors may have overlooked. “There’s such a rich microbial environment everywhere around us,” he says. “Every single place is a niche, where bacteria will have evolved and adapted independently. Soil may have evolved biological warfare, if you like, completely differently than a marine environment, or a muddy environment, or contaminated pond water. There’s a possibility of different chemistry everywhere.”
The Swab and Send campaign fired people’s enthusiasm: Within two months, Roberts received more than £1,000, and hundreds of swabs. Small checks continue to arrive by mail. (The price of participation has gone up, to £30 for five swabs.) Elementary schools invite Roberts to make presentations, and he gives the kids swabs to take home. He has taken sample tubes to parties and to newsrooms. He has two swabs that were swiped across desks in the Houses of Parliament.
