Background/purpose: The ability of probiotics to inhibit adhesion is a crucial characteristic that prevents colonization and infection progression. This study aimed to explore aggregation, adhesion, and cell surface characterization of probiotic and strains and to evaluate the effect of probiotics and their cell-free supernatants (CFSs) as postbiotics on adhesion to human oral keratinocytes.
Materials And Methods: Eight probiotic strains and five reference strains were tested for autoaggregation, coaggregation, adhesin on human oral keratinocytes (H357), and cell surface properties. The anti- adhesion activities of probiotic strains and CFSs were investigated.
Results: The results showed that most probiotics exhibited high adhesion to H357 cells, specifically oral probiotic SD4, SD7, and SD11, and adhesion ability of probiotic strains was strongly related to their autoaggregation, cell surface charges, and hydrophobicity. strains also revealed a high level of adhesion to H357 cells. and showed significantly higher adhesion abilities than others. After a combination of with probiotics or their CFSs, adhesion was significantly reduced. The anti- adhesion property of probiotics was strongly related to their autoaggregation, coaggregation, and adhesion abilities.
Conclusion: This study demonstrated that oral probiotic strains may be useful probiotics for preventing and treating oral candidiasis due to their high ability of aggregation, adhesion, and anti- adhesion to H357 cells.

Periweissella beninensis LMG 25373, belonging to the recently established Periweissella genus, exhibits unique motility and high adhesion capabilities, indicating significant probiotic potential, including resilience under simulated gastrointestinal conditions. This study demonstrates for the first time that P. beninensis LMG 25373^T produces a dextran-type exopolysaccharide (EPS) with a distinctive high degree of branching (approximately 71 % of α-(1 → 6)-linkages and 29 % α-(1 → 3)-linkages).

Background: Long COVID or Post-acute sequelae of COVID-19 is an emerging syndrome, recognized in COVID-19 patients who suffer from mild to severe illness and do not recover completely. Most studies define Long COVID, through symptoms like fatigue, brain fog, joint pain, and headache prevailing four or more weeks post-initial infection. Global variations in Long COVID presentation and symptoms make it challenging to standardize features of Long COVID.

With the in-depth and comprehensive research on probiotic Bacillus, it has become a hot topic in food science. However, the current status of research using bibliometric analysis to assess the application of probiotic Bacillus in food science has not been comprehensively reviewed. The Web of Science (WOS) database was used in this review's bibliometric analysis to determine the hotspots for research as well as the extent of completed experiments.

Aims: Supplementing Lactobacillus alongside antibiotic treatment was a curative strategy to modulate gut microbiota and alleviate antibiotic-associated dysbiosis. But the lactobacilli that are used as probiotics are sensitive or have a low level of resistance to antibiotics, so they usually cannot achieve their beneficial effect, since they are killed by the applied antibiotics. This work aimed to develop the highly resistant Lactiplantibacillus plantarum subsp.
