The tiny zebrafish has enabled some big advances in biomedical research, thanks in part to its optical transparency during embryonic stages, which allows for direct, microscopic visualization of biological processes in vivo in real time. Its latest contribution is to our understanding of tuberculosis, a disease in which pathogenic mycobacteria induce the formation of complex cellular aggregates called granulomas.
