SRL does not cause glucose intolerance, hypertension, nephrotoxicity or neurotoxicity, offering significant potential advantages over calceneurin inhibitors (CNI). Aim: To report five children treated with SRL. Material and methods: A retrospective review of four children undergoing orthotopic liver transplantation (OLT) and one undergoing renal transplantation

Both Listeria species showed an initial decrease in viable counts followed by the regrowth of the survivors after 1 h in the presence of each bacteriocin. A greater antilisterial effect was observed when the bacteriocins were combined in pairs, maximal inhibition being reached when nisin was involved. When a mix of the three bacteriocins was used, no survivors were observed after 24 h of incubation. Similar results were obtained when the bacteriocin combinations were tested in a meat system, indicating that the use of more than one LAB bacteriocin in combination may be effective in preventing the spontaneous emergence of a bacteriocin-resistant Listeria population.
