Summary: Oral microbiome studies have shown variability in bacterial species associated with caries or oral health across different studies, influenced by factors such as age and sample type. No single bacterial species was consistently associated with caries or oral health in all studies.

Summary: This study evaluated the residual contamination of healing abutments sterilized by dealers of dental implant companies. Approximately 31% of the healing abutments showed visible residual contamination. A significant relationship was found between implant brands and contamination status, indicating that reusing healing abutments is not suitable due to incomplete removal of contaminants.

Summary: The study reports the microbial composition in the buccal cavity of female and male Nile tilapia reared in a recirculating aquaculture system for the first time. Certain bacteria with known metabolic advantages, such as Acinetobacter and Acidobacteria, were more abundant in females compared to males, while opportunistic pathogens like Streptococcus were less prevalent in female buccal cavities. Additionally, there were fewer microbe-microbe interactions of opportunistic pathogens in female fish compared to males.

Summary: This study analyzed the coverage of 16S rRNA gene primers used in oral microbiome studies and identified the best primers. The findings showed that the optimal primers can be utilized for detecting both oral bacteria and archaea, with a wide coverage range.

Summary: Crohn's disease (CD) is a chronic inflammatory bowel disease with an increasing global incidence. Microbial dysbiosis has been recognized as a key factor contributing to CD. This study found distinct microbial dysbiosis in the oral cavity, sputum, and ileum of CD patients, with alterations in microbiota diversity and composition. Additionally, the microbiota changes varied across disease stages.

Summary: By sequencing the microbial communities in samples from patients with primary esophageal squamous cell carcinoma (ESCC) and oral cavity squamous cell carcinoma (OSCC), this study found that these two cancers displayed similar patterns of dysbiosis in their upper aerodigestive microbiota. Certain bacterial genera were commonly enriched or depleted in both types of cancer, suggesting a potential role in the pathogenesis of malignancies.

Summary: The blowfly species Lucilia sericata and Lucilia cuprina play roles as agricultural pests, in forensics, and in medicine. While L. sericata larvae are used in maggot debridement therapy, L. cuprina larvae are major initiators of sheep myiasis in certain regions. Bacterial DNA extraction and sequencing showed that digestive tracts and female salivary glands carried the most bacteria in both species, with genera Pseudomonas and Corynebacterium being highly represented. Further research could focus on key organs like spermathecae and salivary glands to understand the role of bacteria in the blowfly life cycle.

Summary: This study examined the effects of Cry1B protein on the growth and development of non-target natural enemies. The results showed that Cry1B protein had no significant impact on the health indicators of P. astrigera, but it did reduce the number of symbiotic bacteria species and species diversity. The effects of Cry1B protein on symbiotic bacteria varied by growth and development stage and sex.

Summary: This study evaluated the sterilization effectiveness against biofilms on healing abutments used in implant dentistry, revealing that some abutments still had remnant biofilm biomass, including pathogenic species. Further research should be conducted on different materials, design, and connections of healing abutments in relation to clinical disinfection procedures.

Summary: This study used high-throughput sequencing technology to investigate the gut microbiota of different horse breeds and found variations in microbial composition and function. Thoroughbred horses had a more diverse microbiota, while Hybrid horses showed intermediate diversity. The metabolic pathways also differed significantly between breeds.

Summary: The gut microenvironment of houseflies plays a crucial role in their development and immune response. This study isolates and analyzes different bacterial strains from housefly larvae, and finds that the oral administration of various bacteria has differential effects on larval development and immunity. Beneficial bacteria can be used as probiotic additives for larvae feeding, while harmful bacteria could be targeted for pest control. Additionally, the study provides insights into the immune response of houseflies to external microorganism stimulation.

Summary: Soil cadmium (Cd) pollution poses a significant threat to flora and fauna due to its non-degradable and transferable nature. This study investigated the impact of endogenous Cd-polluted mulberry leaves on the gut microbiota of silkworms (Bombyx mori). The results revealed that Cd exposure caused significant changes in the gut bacterial composition of the silkworms, but had negligible effects on the phyllosphere bacteria of mulberry leaves. The findings suggest that the perturbations in the gut microbiota of B. mori are driven by Cd content rather than phyllosphere bacteria.

Summary: We investigated the oral microbiota of 100 healthy dogs and identified a complex community of bacteria and fungi, including potential pathogens to humans. We also observed multiple drug-resistant bacteria in the oral cavity of these dogs. This highlights the risk of transmission of microorganisms from dogs to humans and the challenges in treating infections caused by dog bites.
