Dormant Pseudomonas aeruginosa bacteria (green) colonize tissues as single cells that can be observed here through the Drosophila cuticle, following their escape from the digestive tract in a newly developed latent infection model. They are tolerant to antibiotic treatments and retain their potential for virulence. Melanization, an arthropod-specific host defense plays a key role in the establishment of latency. This study underscores the plasticity of P. aeruginosa behavior in vivo depending on the infection route. Chen et al
