Silver Diammine Fluoride Usage in General Dentistry Offices in Louisiana.

To evaluate the current knowledge and usage of silver diammine fluoride (SDF) by general dentists in Louisiana and to identify primary barriers to the imple- mentation of SDF. A 16-item survey was emailed to 1719 Louisiana Dental Association members to identify factors influencing general dentists' usage of SDF. Eighty-two surveys were completed with a response rate of 4.

Impacts of a DUF2207 Family Protein on Stress Tolerance Responses and Biofilm Formation.

Locus SMU.243 in was annotated as a member of the DUF2207 family proteins highly conserved in all bacteria but with unknown function. To investigate its role in physiology, a SMU.

Lacking Is Viable, but Displays Major Defects in Growth, Stress Tolerance Responses and Biofilm Formation.

appears to possess a sole iron-sulfur (Fe-S) cluster biosynthesis system encoded by the cluster. This study was designed to examine the role of in physiology. Allelic exchange mutants deficient of the whole cluster and in individual genes were constructed.

Complete Genome Sequence of Streptococcus mutans 27-3, an Active Extracellular Membrane Vesicle Producer.

Here, we report the complete genome sequence of Streptococcus mutans 27-3. Isolated from a caries-active patient, 27-3 produces significantly more extracellular membrane vesicles than the commonly used laboratory strain UA159. This study provides useful information for comparative genomic analysis and better understanding of regulation of vesiculogenesis in this bacterium.

Azalomycin F Eradicates Biofilm by Rapidly Penetrating and Subsequently Inducing Cell Lysis.

Antimicrobial resistance has emerged as a serious threat to public health. Bacterial biofilm, as a natural lifestyle, is a major contributor to resistance to antimicrobials. Azalomycin F, a natural guanidine-containing polyhydroxy macrolide, has remarkable activities against Gram-positive bacteria, including , a major causative agent of hospital-acquired infections.
