Meningitis Model Shows Infection’s Sci-Fi-Worthy Creep Into the Brain

A transparent zebrafish larva is infected with Cryptococcal meningitis and photographed under a microscope. Scientists observe as the infection (visible red orbs) takes over the brain. Macrophages (shown in blue) attack the infection as it travels through green blood vessels and throughout surrounding tissue. The eyes of the fish are located at the top- and bottom-left corners of the image. Stefan Oehlers/Duke Medicine
