While typically used at high concentrations (1\u20132\u00a0mg\/ml), oral bacteria can be exposed to sublethal concentrations due to the bioavailability and protective barrier of biofilms (dental plaques). Sublethal concentrations can cause transcriptional remodelling of bacteria such as Streptococcus mutans, a key player in dental caries. Using an RNA-seq approach, this report provides a compendium on the effect of sublethal concentrations of chlorhexidine on the transcriptome of S. mutans as planktonic cells and in biofilm states. Streptococcus mutans showed major transcriptional remodelling between planktonic and biofilm states. The transcriptional response towards chlorhexidine was more pronounced in planktonic cells compared to sessile cells. However, the response observed for biofilm-associated cells was not specific to chlorhexidine, as the transcriptional response in biofilms exposed to the \u03b2-lactam amoxicillin was similar to those observed for chlorhexidine. Furthermore, we found that S. mutans modulates the transcription of a multitude of ABC transporters in both planktonic and biofilm-associated cells upon exposure to these antimicrobials.<\/jats:p>","DOI":"10.1093\/femsle\/fnaf100","type":"journal-article","created":{"date-parts":[[2025,9,23]],"date-time":"2025-09-23T12:32:29Z","timestamp":1758630749000},"source":"Crossref","is-referenced-by-count":3,"title":["Transcriptomic
