Summary: Enterococcus faecalis can form cardiac microlesions during severe infection, with DsbA protein playing a key role in virulence and microlesion formation. Additionally, the bacterium promotes cardiomyocyte death and modulates proinflammatory cytokine levels, contributing to the immune response suppression.

Summary: This research aimed to explore the relationship between TNF-alpha, L. acidophilus, L. gasseri, obesity, and early childhood caries. The study found that in obese children, an increase in BMI and TNF-alpha levels was associated with an increase in the number of decayed surfaces. In eutrophic children, the presence of L. gasseri and L. acidophilus was linked to an increase in the number of decayed surfaces.

Summary: This study investigated the prevalence of virulence factors, drug resistance and its genetic determinants, and clonal lineages of E. faecalis and E. faecium clinical isolates in northern Japan. The results showed that E. faecalis isolates had a higher prevalence of virulence factors promoting bacterial colonization compared to E. faecium. There were evident differences in resistance to certain antibiotics and its determinants between the two species. Additionally, the first identification of optrA gene in ST480 E. faecalis in Japan was reported.

Summary: The study evaluated Enterococcus faecalis strains isolated from endodontic failures for the presence of virulence genes, biofilm formation capacity, and activity of gelatinase and beta-lactamase. Results showed diverse patterns of virulence gene detection among the strains, with most capable of forming biofilm. Some strains exhibited gelatinase production, while beta-lactamase resistance was detected in different isolates.

Summary: The study evaluated the antimicrobial effectiveness of a novel nanocomposite (NC) prepared using a combination of zinc oxide, silver, and chitosan with lemon extract as a cross-linking agent against Enterococcus faecalis (E. faecalis). The NC showed improved antimicrobial action against E. faecalis compared with its individual components under laboratory conditions.

Summary: Enterococcus faecalis, a commensal in the human gastrointestinal tract, is a known cause of nosocomial infections. Its transition from a planktonic to a sessile state, along with the acquisition of multidrug resistance, poses challenges for treatment. Several key genes and molecular pathways, including quorum sensing, aggregation substance, surface adhesions, stress-related response, and sex pheromones, play critical roles in the sessile state. It is crucial to decode the hidden agenda of E. faecalis and understand the factors influencing biofilm formation in order to develop novel strategies to combat infections.

Summary: The study evaluated the effectiveness of Antimicrobial Photodynamic Therapy (aPDT) on Enterococcus faecalis and Actinomyces israelii in root canal treatment. Results showed that aPDT did not significantly improve periapical repair compared to conventional treatment. Molecular methods may not be efficient in detecting bacteria post-treatment, and colony-forming units could be an effective quantifying method. Further research is needed to determine the potential effectiveness of aPDT.

Summary: The study evaluated the influence of physical exercise on the concentration of salivary immunoglobulin A (sIgA) in athletes, showing that physical exercise does not have a significant impact on sIgA concentration. However, due to the risk of bias and very low certainty of evidence, further studies with better methodologies are needed.

Summary: This study investigated the carriage prevalence, risk factors, serotypes, and antimicrobial resistance among pneumococcal isolates recovered from adults living in a Brazilian urban slum. The results showed a low frequency of pneumococcal carriage among the adult population but a high diversity of serotypes. Concerningly, some isolates displayed resistance to antimicrobial agents.

Summary: This study investigated the prevalence, capsular types, antimicrobial resistance, and risk factors among children in Niteroi city, Brazil, after nine years of using the PCV10 vaccine. The findings showed that PCV10 serotypes were almost eliminated, but the frequency of multidrug-resistant isolates, particularly associated with the serotype 6C/D, remains a concern. Replacing PCV10 with PCV13 is recommended to reduce the proportion of erythromycin-resistant and penicillin non-susceptible isolates.

Summary: The aim of this study was to investigate the association between single nucleotide polymorphisms in nitric oxide synthase and persistent apical periodontitis. The results showed that the genotype and allele distributions were not statistically significant between the persistent apical periodontitis and healed groups. Therefore, this study did not find an association between single nucleotide polymorphisms and persistent apical periodontitis.
