Fig 1. Timeline of the immunizations and challenge infections of zebrafish with the parasite Ichthyophthirius multifiliis.

Timeline of exposures and samplings regarding zebrafish used for A) gene expression analyses and B) image analyses investigating neutrophil recruitment. The pink and the blue areas frame the periods of immunizations and challenge infections, respectively. Periods between immunizations and sampling points are indicated as well as immunization and challenge dosages of the parasite.
