We enlisted citizen scientists to help us classify the many thousands of photographs of the different samples of M. tuberculosis collected by CRyPTIC growing on different concentrations of antibiotics by launching the BashTheBug project on the Zooniverse platform back in April 2017.

In this paper, published in eLife, we investigate how to form a consensus from the many classifications made by the volunteers and demonstrate that the crowd of BashTheBug volunteers are sufficiently accurate (and almost sufficiently reproducible) to pass the ISO standard for antibiotic susceptibility testing.
