Summary: Cardiac fibrosis is a fundamental process in cardiac remodeling and is associated with almost all types of cardiovascular diseases. This study explores the relationship between cardiac fibrosis and gut microbiota, finding that dysbiosis of the gut microbiota alone cannot cause cardiac fibrosis. However, healthy fecal microbiota transplantation can alleviate cardiac fibrosis. By targeting the gut microbiota and metabolites, such as probiotics, it is possible to develop new strategies for treating cardiovascular diseases.

Summary: The first microbial colonizers of the infant gut are members of the genus Bifidobacterium, which exhibit different activities beneficial to their host. However, Amoxicillin-clavulanic acid (AMC), the most commonly prescribed antibiotic during infancy, can reduce the diversity of gut microbiota. This study investigated the potential positive effects of AMC-resistant bifidobacterial strains in maintaining the diversity of gut microbiota during AMC treatment.

Summary: This review investigates the roles of Bifidobacterium animalis subsp. lactis HN019 (B. lactis HN019 (TM)) in gut health and its mechanisms of action. Research supports the hypothesis that B. lactis HN019 (TM) has a beneficial role in maintaining intestinal barrier function and normal physiological function in immunosenescent elderly, as well as reducing intestinal transit time and increasing bowel movement frequency in functional constipation.

Summary: This study found that Bifidobacterium pseudolongum CCFM1253 can protect against lipopolysaccharide-induced acute liver injury by regulating inflammation, antioxidative enzymes, intestinal microbiota composition, and liver metabolism. Therefore, it has the potential to serve as a probiotic to improve host health.

Summary: This study aimed to investigate the gut colonization capacity of Bifidobacterium breve CCFM1025 and developed a quantitative PCR assay based on a specific gene sequence. The results showed that CCFM1025 could be quantified in fecal samples and remained detectable in volunteer feces 14 days after cessation of administration, indicating its favorable colonization characteristics. Therefore, CCFM1025 has the ability to colonize the healthy human gut.

Summary: The study found that high doses of Bifidobacterium breve YH68 used alone or in combination with vancomycin and metronidazole have significant therapeutic effects on pCDI mice, reducing C. difficile numbers and toxin levels, decreasing inflammation, and improving tissue pathology. The combination also alleviates the damaging effect of antibiotics on the gut microbiota.

Summary: This study examined the extracellular vesicles (EVs) secreted by a newly sequenced Gram-positive human gut symbiont strain, Bifidobacterium longum AO44. The EVs were found to have anti-inflammatory effects, inducing the secretion of IL-10 from splenocytes and dendritic cells (DC)-CD4+ T cells co-cultures. The protein content of the EVs was enriched in ABC transporters, quorum sensing proteins, and extracellular solute-binding proteins, which are known to play a significant role in the anti-inflammatory effects of other strains of B. longum. This study highlights the importance of bacterial vesicles in modulating the host immune system and suggests their potential as future therapeutics.

Summary: The complete genome sequence analysis of Bifidobacterium longum subsp. longum BCBL-583 isolated from a Korean female fecal sample showed its safety for human consumption as it lacked virulence factors and antibiotic resistance genes. It also exhibited potential benefits for food processing, cholesterol reduction, and anti-inflammation activities. Animal studies demonstrated that the administration of BCBL-583 to high-fat diet mice reduced cholesterol levels, decreased pro-inflammatory cytokines, and increased anti-inflammatory cytokines. Microbiome analysis revealed changes in gut microbiota composition, suggesting its potential for promoting gut health.

Summary: The establishment of the gut microbiota is influenced by factors such as gestational age, delivery mode, and infant feeding habits, leading to qualitative and quantitative changes in the bifidobacterial population. Understanding the impact of perinatal factors on the gut microbiota, especially at low taxonomic levels, is crucial for the development of rational strategies for promoting a healthy early microbiota development. The study provides insights for selecting the most suitable Bifidobacterium species for different groups of neonates and developing bifidobacteria-based products.

Summary: This study found that different strains of B. longum have strain-specific effects in alleviating hypercholesterolemia, mainly due to differences in bile salt deconjugation ability, cholesterol assimilation ability, expressions of key genes involved in cholesterol metabolism, and alterations of gut microbiota.

Summary: 1-kestose is the smallest component of fructooligosaccharides and has significant bifidogenic effects. However, there is a lack of in vivo studies on the synergistic effects of 1-kestose and Bifidobacterium longum in the gut. We demonstrate the synergistic impact of this combination in mice by using an appropriate monitoring regimen.

Summary: The genomic era has generated a vast amount of genetic data in bacterial taxonomy, but there is currently no established approach to reliably identify reference strains. In this study, a comprehensive multi-omics approach was developed, using the Bifidobacterium genus as a test case, to identify the optimal reference strains.

Summary: A study compared saliva, nasal mid-turbinate swab, and nasopharyngeal swab samples in 112 ambulatory patients suspected of COVID-19, finding that while saliva samples had lower sensitivity for SARS-CoV-2 detection compared to NP swabs, they could be an interesting alternative sampling method when NP swabs cannot be collected.

Summary: Accumulated evidence shows that genetic and environmental factors contribute to obesity, with gut microbiota playing a critical role in metabolism regulation and the development of chronic diseases. The study used high throughput sequencing to identify microbial differences in obese individuals from Argentina, US, and UK, revealing distinct microbiotypes and metabolic pathway signatures. This indicates that personalized strategies for managing obesity based on microbiome configuration could be promising.

Summary: A new real-time PCR assay using SYBR Green has been developed for the detection of low levels of Pneumocystis jirovecii with higher sensitivity. This assay targets two regions simultaneously using two primer sets, and it has been found to be more rapid and simpler compared to the current nested-PCR methods. The new assay was able to detect P. jirovecii in samples that were negative for both rounds of nested-PCR, demonstrating its ability to detect low levels of the pathogen.
