What is a key outcome of the study regarding long-term exposure to CHX on Streptococcus mutans?
- Persistence of CHX-induced variants in the oral cavity
- Increased competitiveness against commensal oral streptococci
- Upregulation of dltC and dltD genes in CHX-resistant strains (correct)
- Decreased hydrophobicity in SM-Cs compared to parental strains
How does continuous exposure to CHX affect resistance development in Streptococcus mutans?
How does continuous exposure to CHX affect resistance development in Streptococcus mutans?
- It decreases hydrophobicity in the bacterial strains
- It results in an increase in MIC after 10 passages (correct)
- It leads to a reduction in minimum inhibitory concentration (MIC)
- It induces CHX sensitivity in the parental strains
