show Abstracthide AbstractStreptococcus suis is a Gram-positive pathogen causing septicemia and meningitis in pigs and humans. We previously found that sRNA rss04 contributes to meningitis induction by regulating capsule synthesis and inducing biofilm formation in a mouse infection model. However, its targets are unknown. In this study, we employed MS2-affinity purification coupled with RNA sequencing (MAPS) to identify the targets of rss04.
