In the co-cultivation of L. sporogenes and B. clausii probiotic strains, obtained from "Lactovit Forte" and "Enterogermina" preparations and strains of E. coli ATCC 25922 and S. aureus ATCC 25923, an antagonistic interaction was determined. The addition of 0.0313 mg/ml of ciprofloxacin enhanced the antagonistic interaction between probiotic strains, in particular B. clausii and cultures of E. coli ATCC 25922 and S. aureus ATCC 25923.enhuman microbiotaantagonistic activityprobiotic drugsantibioticsArticle
