Oral candidiasis presents with multiple clinical manifestations. Among known pathogenic species, is the most virulent and acts as the main causative fungus of oral candidiasis. Novel treatment modalities are needed because of emergent drug resistance and frequent candidiasis recurrence. Here, we evaluated the ability of L8020, isolated from healthy and caries-free volunteers, to prevent against the onset of oral candidiasis in a mouse model. Mice were infected with , in the presence or absence of L8020. The mice were treated with antibiotics and corticosteroid to disrupt the oral microbiota and induce immunosuppression. We demonstrated that oral consumption of L8020 by -infected mice abolished the pseudomembranous region of the mouse tongue; it also suppressed changes in the expression levels of pattern recognition receptor and chemokine genes. Our results suggest that L8020 has protective or therapeutic potential against oral candidiasis, which supports the potential use of this probiotic strain for oral health management.
口腔念珠菌病有多种临床表现。在已知的致病菌种中, 是最具致病性的,也是口腔念珠菌病的主要致病真菌。由于出现耐药性和念珠菌病频繁复发,需要新的治疗方法。在此,我们评估了从健康无龋志愿者中分离出的L8020在小鼠模型中预防口腔念珠菌病发病的能力。在有或没有L8020的情况下,用 感染小鼠。用抗生素和皮质类固醇对小鼠进行处理,以破坏口腔微生物群并诱导免疫抑制。我们证明,感染 的小鼠口服L8020消除了小鼠舌头的假膜区域;它还抑制了模式识别受体和趋化因子基因表达水平的变化。我们的结果表明,L8020对口腔念珠菌病具有保护或治疗潜力,这支持了这种益生菌菌株在口腔健康管理中的潜在用途。
