Anti-oral cancer properties of potential probiotic lactobacilli isolated from traditional milk, cheese, and yogurt.

A Nature study explored the potential of Lactobacillus strains, isolated from traditional dairy products like cheese, milk, and yogurt in Iran, as probiotics with anti-cancer properties against oral cancer. Researchers tested 21 Lactobacillus strains on oral cancer cell lines and identified four (Y33, M45, C5, C28) with promising probiotic characteristics, including good viability, antibiotic resistance, and strong adhesion to human intestinal cells.
