BACKGROUND: Streptococcus mutans is a major pathogen responsible for dental caries. Arginine is a promising potential caries preventive agent which can inhibit the growth of S. mutans. However, the mechanism whereby arginine inhibits S. mutans growth r...

Streptococcus pneumoniae is a leading cause of community-acquired pneumonia and bacteraemia and is capable of remarkable phenotypic plasticity, responding rapidly to environmental change. Pneumococcus is a nasopharyngeal commensal, but is responsible for severe, acute infections followin...

We systematically investigated RcrR's contribution to cariogenic virulence using isogenic wild-type, DeltarcrR deletion mutant, and complemented strains. We assessed bacterial growth, biofilm architecture, acid tolerance, and H+-ATPase activity. To delineate the global regulatory network, we inte...

Extracellular membrane vesicles (EMVs) are produced by many Gram-positive organisms, but information regarding vesiculogenesis is incomplete. We used single gene deletions to evaluate the impacts on Streptococcus mutans EMV biogenesis of Sortase A (SrtA), which affects S. mutans...

The Antibiotic Resistant Sepsis Pathogens Framework Initiative aims to develop a framework dataset of 5 sepsis pathogens (5 strains each) using an integrated application of genomic, transcriptomic, metabolomic and proteomic technologies. The pathogens included in this initiative are: Escheric...

Streptococcus pneumoniae is the primary cause of community-acquired bacterial pneumonia with rates of penicillin and multi-drug resistance exceeding 80% and 40%, respectively. The innate immune response generates a variety of antimicrobial agents to control infection including zinc stres...

In this study, we proposed to obtain the differential metabolic pathways before and after the development of macrolide resistance in Streptococcus suis strain ATCC700494 and the macrolide resistant strain obtained by pre-laboratory induction of strain ATCC700794 as the test strains by non-targete...
