Swab and Send

Help us find the next antibiotic

A close-up of a gloved researcher’s hands holding a petri dish containing diverse microbial colonies. The dish shows a variety of bacterial and fungal growth in different colours and shapes, including green, blue, orange, black, and brown spots, as well as larger textured colonies. Other petri dishes are visible blurred in the background on a lightbox surface, highlighting microbiological analysis in a laboratory setting.

Antibiotic resistance is rising, and we need new antibiotics to protect health worldwide. By supporting Swab and Send, you help our researchers test bacteria and fungi from everyday places for compounds that could become future treatments.

We’re always looking to the future. Our ambition is to be recognised as a global organisation championing world-class research while providing top-level education. We will continue to build equitable and sustainable partnerships to strengthen our impact.

Why this matters

Antibiotics help us treat bacterial infections in people and animals. They also play an important role in food production.

But bacteria evolve quickly. As resistance grows, some antibiotics stop working. This is antimicrobial resistance (AMR), and it is a major global threat.

A major global study estimated that in 2019, bacterial AMR was linked to 4.95 million deaths, including 1.27 million deaths directly caused by AMR.

How Swab and Send works

  • We already test tens of thousands of microbes. With your support, we can go further.

  • 1. You donate to support our work.

  • 2. If you donate £30 or more, we send you a swab pack.

  • 3. You collect swabs from everyday places, for example, the back of a fridge, a phone, or a light switch and send them back to us.

  • 4. We analyse your swabs in the lab to look for microbes that could produce new antibiotics.

Professor Adam Roberts

“When your swab arrives, we grow the bacteria and fungi, then test them against antibiotic-resistant microbes. If anything shows promise, we save it for further research.”

What happens to your swab when it arrives at Adam’s lab?

Follow your swab from the post to the Petri dish. See how we grow microbes, test them against antibiotic-resistant organisms, and store anything that looks promising.

Where have some of our swabs come from?

From slate mines to science centres, people have swabbed all sorts of places. Explore a few of the most unusual samples and the stories behind them.
