Summary: Increased prevalence and abundance of Selenomonas sputigena have been associated with periodontitis, a chronic inflammatory disease of tooth-supporting tissues, for more than 50 years. Molecular surveys of periodontal disease have confirmed the disease association of periodontal pathogens and highlighted lesser-known organisms such as Filifactor alocis and S. sputigena. However, the pathogenic potential and virulence mechanisms of S. sputigena remain unknown. This study demonstrates that S. sputigena infection induces inflammation and leukocyte recruitment, suggesting its contribution to periodontitis.

Summary: This study found that metal oxide nanoparticles can reduce the incidence of tomato bacterial wilt and alter the composition and structure of the rhizosphere bacterial community. Among them, the application of CuO nanoparticles significantly affected the abundance of beneficial Streptomyces bacteria. This research provides evidence and strategies for using metal oxide nanoparticles to prevent and control soil-borne disease tomato bacterial wilt.

Summary: In this study, RNA secondary structures of influenza A virus were determined using chemical mapping and 4-thiouridine (4sU) crosslinking, revealing both universal and unique features of different strains. The method highlighted the three-dimensional properties and allowed for proposing long-range interactions in the RNA secondary structure. The combination of 4sU mapping with chemical mapping and bioinformatic analysis could enhance RNA structure determination and target recognition for antisense strategies or viral RNA detection.

Summary: This study aimed to analyze the changes in penile microbiome before and after circumcision in pediatric population and evaluate the pathways related to inflammation, barrier protection, and energy metabolism. The results showed a significant reduction in bacteria and fungi after circumcision, especially anaerobic bacteria, which are potential inducers of inflammation and cancer. This is the first study to demonstrate the changes in microbiome after circumcision and provide explanations for the differences in cancer and inflammatory disorders in adulthood among healthy infants after circumcision.

Summary: This study focuses on the analysis of gut microbiota and gonad microbiota from three different spider species. High-throughput sequencing identified variations in microbial composition among different spider species, especially notable differences between female and male spiders. The results also suggest similarities between the gut and ovarian microbiota of spiders, implying potential pathways for microbial transmission within female spiders between the gut and gonad.

Summary: Our study found differences in the rhizosphere bacterial community structures of weedy rice and cultivated rice. The rhizosphere bacterial community and co-occurrence network of cultivated rice changed when disturbed by weedy rice. These differences give weedy rice a nutritional competitive advantage in paddy soils.

Summary: Probiotics may help achieve a balanced microbiome in periodontitis by interfering with the colonization of Aggregatibacter actinomycetemcomitans in the oral cavity. This in vitro study evaluated the effect of two commercially available lactobacilli strains on gingival epithelial cells infected with A. actinomycetemcomitans. The results suggest that these probiotics may reduce the ability of A. actinomycetemcomitans to interact with gingival epithelial cells and modulate the cells' response.

Summary: The oral cavity contains various microorganisms that can cause diseases like periodontitis. Traditional periodontal treatment focuses on mechanical control of biofilm, but chemical control can also be useful. Natural products such as propolis, aloe vera, green tea, cranberry, calendula, myrrha, and salvia have shown potential as oral hygiene products due to their antimicrobial and anti-inflammatory properties.

Summary: This study aimed to evaluate the antibacterial gene expression of dendritic cells challenged with LPS and probiotics. The results showed that LPS upregulated more genes related to inflammation and immune response compared to the groups where probiotics were added. Although probiotics decreased several genes upregulated by LPS, they still upregulated some genes encoding cytokines. Additionally, one specific probiotic promoted the secretion of these proteins.

Summary: This study found that Bifidobacterium animalis subspecies lactis HN019 can reduce the sequelae of experimental periodontitis in rats by modulating systemic parameters. Bifidobacterium lactis HN019 can decrease dyslipidemia, insulin resistance, proteinuria levels, systolic blood pressure, hepatic steatosis, and expression of adipokines, as well as improve intestinal microbiota imbalance and prevent alveolar bone loss. These findings highlight the importance of Bifidobacterium lactis HN019 in preventing the damage caused by periodontitis.
