“…Through oral administration of CA119, almost no signi cant changes were found in the indicators of oxidative stress except for MPO (P < 0.001). However, through oral inoculation, the activity of antioxidant enzymes in the OPM group was signi cantly increased, including T-SOD (P < 0.05) and T-AOC (P < 0.001), these enzymes can remove free radicals and other oxidative substances generated in cells [49,50], to protect periodontal tissue from oxidative damage [6,49]. At the same time, we found that the levels of oxidative substances in the OPM group were signi cantly reduced, including MDA (P < 0.001), H 2 O 2 (P < 0.001), and MPO (P < 0.001, Fig.…”

Periodontitis is a chronic in ammatory disease characterized by the overgrowth of Porphyromonas gingivalis and Fusobacterium nucleatum in the oral cavity. This not only severely affects alveolar bone and connective tissues but also has potential associations with distal intestinal in ammation. This study aimed to elucidate the therapeutic effects of Streptococcus cristatus CA119 on experimental periodontitis in rats and its impact on intestinal morphology. The results demonstrate that CA119 can colonize the oral cavity and exerts antagonistic effects on P. gingivalis and F. nucleatum, leading to a signi cant reduction in the oral pathogen load. Following CA119 intervention, a signi cant alleviation in weight loss in rats induced by periodontitis was observed (P < 0.001). CA119 also regulated the expression of IL-6 (P < 0.05), IL-1β (P < 0.001), IL-18 (P < 0.001), COX-2 (P < 0.001), iNOS (P < 0.001), and MCP-1 (P < 0.01) in the gingival tissue. Additionally, CA119 reduced oxidative stress levels in rats and enhanced their antioxidant capacity. Microcomputed tomography (micro-CT) and histological analysis revealed that CA119 signi cantly reduced alveolar bone loss and reversed the down-regulation of OPG/RANK (P < 0.001). Furthermore, CA119 exhibits a signi cant protective effect against intestinal in ammation induced by periodontal disease and improves the colonic morphology in rats. In conclusion, this study demonstrates the role of CA119, a potential oral probiotic, in preventing and treating experimental periodontitis, which underscores the potential of probiotics as a complementary approach to traditional periodontal care.
