Streptococcus dentisani inhibits the growth of Candida albicans and Candida glabrata: in vitro assay.
Background: Probiotic bacteria inhibit aggregation, biofilm formation, and dimorphism of Candida spp. However, the effects of a new probiotic, Streptococcus dentisani, on the growth of Candida albicans and Candida glabrata biofilms are unknown.
Objective: To determine the effect of S. dentisani on the different phases of C. albicans and C. glabrata biofilm development.
Methods: Growth quantification and ultrastructural analyses were performed on biofilms of C. albicans ATCC 90028, C. glabrata ATCC 2001, and clinical isolates of C. albicans from oral candidiasis (CA-C1), caries (CA-CR1), and periodontal pocket (CA-P1) treated with cell suspensions of S. dentisani CECT 7746. Cell viability was determined by quantifying colony-forming units (CFU/mL). The ultrastructural analyses were done with atomic force microscopy.
Results: S. dentisani induced a significant reduction (p < 0.05) of CFU/mL of immature and mature biofilm in all strains of C. albicans and C. glabrata. Microscopic analysis revealed that S. dentisani reduced C. albicans density in mixed biofilm. The fungus-bacteria interaction affected cell membrane integrity in yeast.
Conclusion: For the first time, our data elucidate the antifungal effect of S. dentisani on the development of C. albicans and C. glabrata biofilms, supporting its usefulness as a niche-specific probiotic to prevent and treat oral dysbiosis.
期刊介绍：
International Microbiology publishes information on basic and applied microbiology for a worldwide readership. The journal publishes articles and short reviews based on original research, articles about microbiologists and their work and questions related to the history and sociology of this science. Also offered are perspectives, opinion, book reviews and editorials.
A distinguishing feature of International Microbiology is its broadening of the term microbiology to include eukaryotic microorganisms.
