04 Apr 2019 --- A patent-pending probiotic mix may help shield patients who suffer from gastrointestinal (GI) diseases from harmful biofilms – antibiotic-resistant microbial communities. This is according to a study from the Case Western Reserve University and University Hospitals (UH) Cleveland Medical Center. The study tested the ability of a novel probiotic to prevent and treat biofilms containing yeast bacteria. The findings show that the probiotic weakened the bacteria and stunted its growth. The researchers conclude that the new probiotic may boost the prevention and treatment of GI diseases.
