This review examines the role probiotics can play in reducing and inhibiting the growth of biofilms that cause bacterial infections in humans. The use of probiotics as an inhibitory agent against biofilms is a new field of study that requires further research. As of now, there is little research or scientific literature to defend the health claims of several commercially sold probiotics. Also, biofilms are a fairly new field of study even though biofilms are the cause of most bacterial infections. Since biofilms have an increased antibiotic resistance, it has become increasingly more important to find alternative treatments for bacterial infections. However, there have been a couple of studies that have shown positive results for probiotics inhibiting the growth of different types of biofilms such as Lactobacillus acidophilus in patients with dental caries caused by the biofilm formation of Streptococcus mutans. Specifically, the biosurfactant
of the probiotic was used to disrupt the biofilm. Another study was done on patients with Clostridium difficile infection who showed a decline in symptoms when treated with the probiotic yeast Saccharomyces boulardii as an additive to antibiotic treatments . While the oral health and gut health fields have started to utilize the benefits of probiotics, the effect of probiotics on the biofilms that cause infections for patients with medical devices has yet to be studied.
