Researchers from Universitat Autònoma de Barcelona and Laboratorios Ordesa S. L. (Barcelona, Spain), used our v-DNA reagent and v-DNA buffer products for bacterial DNA extraction from fecal samples with the aim to demonstrate the potential of the probiotic strain Bifidobacterium longum subsp. infantis CECT 7210 to reduce the intestinal colonization by pathogens and thus prevent gastrointestinal infections in a weaning piglet model.
