OBJECTIVE To construct double gene deletions at the htrA and clpP loci on the chromosome of Streptococcus mutans (Sm) and to remove the antibiotic resistance markers with the Cre-loxP(*) site-specific recombination system. METHODS The htrA gene was cloned into the pGEM-T-Easy TA cloning vector and then inactivated via the insertion of a kanamycin(More)
OBJECTIVE To detect the AI-2 quorum-sensing pathway and construct the luxS g-ene allelic exchange plasmid of Streptococcus mutans. METHODS To detect AI-2 pathway in Streptococcus mutans, the Vibrio harveyi BB170 was used as reporter strain. The PCR fragments of the upstream and downstream regions of luxS and the Erythromycin resistance gene were amplified(More)
OBJECTIVE To investigate the function of luxS in sulfurmetabolism of Streptococcus mutans (Sm). METHODS The growth with absorbency (A) of the standards and mutant strains was measured and analyzed in the sulfur-limited defined medium at different periods. The laser scanning confocal microscopy (LSCM) was used to observe and compare the biofilm thickness(More)
