Comparative transcriptome analysis reveals a serotype-specific immune response in Nile tilapia (Oreochromis niloticus) infected with Streptococcus agalactiae

The goal is to assess the impact of two different strains of Streptococcus agalactiae (SA8-UEL, serotype Ib, and SA10-UEL, serotype III) in the brain of Nile tilapia juveniles. Fish were intraperitoneally infected with the bacteria and the brain was collected upon the appearance of erratic swimming.
