The phyllosphere supports a tremendous diversity of microbes and other organisms. However, little is known about the colonization and survival of pathogenic and beneficial bacteria alone or together in the phyllosphere across the whole plant life-cycle under herbivory, which hinders our ability to understand the role of phyllosphere bacteria on plant performance. We addressed these questions in...

Human milk oligosaccharides are complex sugars that function as selective growth substrates for specific beneficial bacteria in the gastrointestinal system. Bovine milk is a potentially excellent source of commercially viable analogs of these unique molecules. However, bovine milk has a much lower concentration of these oligosaccharides than human milk, and the majority of the molecules are sim...

Human intestinal bacteria have many roles in human health, most of which are beneficial or neutral for the host. In this review, we explore a more sinister side of intestinal bacteria; their role as traffickers in antibiotic resistance genes. Evidence is accumulating to support the hypothesis that intestinal bacteria not only exchange resistance genes among themselves but might also interact wi...

    In conclusion, UTI is a globally distributed disease with emergence of multidrug-resistant bacteria; thus, new drug discovery or activation of previously used drugs is an urgent issue. Methenamine has been suggested as a beneficial agent for the UTI prevention as it works as a urinary antiseptic by safely producing formaldehyde to prevent bacterial growth while avoiding bacterial resistance...

PURPOSE OF REVIEW Probiotics are live, nonpathogenic bacteria that confer health benefits beyond their nutritional value. In inflammatory bowel disease, where changes in bacterial flora have been demonstrated, there is an increasing interest in modulating the flora with probiotic strains. The beneficial effect of probiotics is demonstrated mainly in pouchitis and ulcerative colitis; however, th...

Despite preventive measures, incidence of burns is still one of the important medical problems. Nowadays, it has been suggested that some strains of probiotic bacteria have beneficial effects in treatment of skin injures like skin wounds. The aim of the present study was to evaluate the effects of Lactobacillus acidophilus on second-degree burn wounds in rats. Second-degree burn wounds were ind...
