Bifidobacteria is a genus of probiotic bacteria commonly used to support gut health and modulate the immune system. There is a moderate level of scientific evidence suggesting that supplementation with certain strains of Bifidobacteria can be beneficial in preventing or reducing the severity of some bacterial infections, particularly those affecting the gastrointestinal tract. Clinical studies have shown that Bifidobacteria can help inhibit the growth of pathogenic bacteria such as Clostridium difficile, Escherichia coli, and Salmonella species, primarily through competitive exclusion, enhancement of mucosal barrier function, and production of antimicrobial substances like bacteriocins and organic acids.

Meta-analyses and randomized controlled trials have found that certain Bifidobacteria strains may reduce the incidence or duration of infectious diarrhea in children and adults, especially in the context of antibiotic-associated or acute bacterial gastroenteritis. Some evidence also exists for their adjunctive use in managing bacterial vaginosis and respiratory tract infections, though results are mixed and often strain-specific. It is important to note that the efficacy depends heavily on the specific strain, dosage, and patient population, and not all Bifidobacteria strains have demonstrated clear benefits. Overall, while Bifidobacteria are not a replacement for antibiotics in treating bacterial infections, they may serve as a supportive therapy, especially in maintaining or restoring healthy microbiota and reducing infection risk.
