This application belongs to the field of microbial technology, specifically disclosing the application of *
Lactobacillus fermentum* BLF03 in anti-Candida activity. *
Lactobacillus fermentum* BLF03 was deposited on November 6, 2025, at the China General
Microbiological Culture Collection Center (CGMCC) with accession number CGMCC No. 36521. This application proposes a *
Lactobacillus fermentum* BLF03 strain resistant to *
Candida albicans* and *
Candida krusei*, which can significantly inhibit the growth,
reproduction, and hyphal transformation of *
Candida albicans* and *
Candida krusei* at the
in vivo level, alleviate Candida-induced infection symptoms, reduce the expression level of the
inflammatory marker procalcitonin (PCT) after Candida infection, improve the inflammatory stress response induced by infection, and has a significant protective effect against
tissue damage caused by Candida invasion. It also has targeted preventive and adjunctive therapeutic effects on Candida infections in the urogenital tract and other sites, providing a new, safe, and highly
effective strain for anti-Candida products.
