Shigella serotypes associated to MSM transmission establish persistent infection in zebrafish. Shigella flexneri

In high-income countries, sexual transmission among men who have sex with men (MSM) is the dominant cause of domestic Shigella transmission. Torraca et al. discover that three serotypes of Shigella most associated with MSM transmission also persist in zebrafish. These results indicate that Shigella serotypes associated with MSM transmission can establish carriage in the host, and highlight the use of zebrafish infection to study Shigella persistence in humans.
