Background: Streptococcus mutans is studied for its acidogenic and aciduric characteristics, notably its biofilm formation in the presence of sucrose, toward its role in the caries process. Variations in both genotype and phenotype have been reported among clinical isolates of S. mutans.

is considered by many to be the deadliest microbe, with the estimated annual cases numbering more than 10 million. The bacteria, including , are classified into nine major lineages and hundreds of sublineages, each with different geographical distributions and levels of virulence. The phylogeographic patterns can be a result of recent and early human migrations as well as coevolution between the bacteria and various human populations, which may explain why many studies on human genetic factors contributing to tuberculosis have not been replicable in different areas.

Article Synopsis
  • - The study examined the effects of starting antiretroviral therapy (ART) during acute or early HIV infection on the viral reservoir and immune responses in participants from various regions.
  • - Results showed that starting ART earlier resulted in lower levels of HIV DNA in the blood, particularly for those who began treatment in the very early stages of infection, but it did not fully eliminate the presence of HIV-infected cells.
  • - Despite achieving viral suppression at 48 weeks, the study found no strong correlation between HIV DNA levels and the strength of HIV-specific T cell immune responses, suggesting that early treatment may reduce, but not completely prevent, viral rebound after stopping ART.

Background: The continuously increasing demand for removable denture appliances and the importance of adequate denture cleaning have led to the development of various denture cleansing products. The aim of this study was to evaluate the efficacy of two novel denture cleansing agents (GE and TM) and three commonly available cleansers (0.5% sodium hypochlorite; NaClO, 0.

Purpose: To study the antimicrobial effects of a novel vinegar-based denture cleansing agent on oral Streptococci and Candida species and the inhibitory effects on pre-formed bacterial and Candida biofilms on denture base.

Methods: The microorganisms used in this study were Streptococcus mutans (S. mutans), Streptococcus sobrinus (S.
