Abstract

The topical application of lactobacilli is receiving attention for the prevention of superficial skin and burn wound infections. We studied the properties of Lactobacillus plantarum immobilized in calcium alginate films and investigated the antibacterial activity of these films in a model burn wound in rats. A multiresistant clinical isolate, VIM-2-metallo-β-lactamase-producing Pseudomonas aeruginosa, was used as the indicator strain. Films incorporating L. plantarum at cell concentrations of 10(8)cfu/mL caused a reduction of 5-6 log(10) in P. aeruginosa in the model burn wounds. L. plantarum immobilized in freeze-dried calcium alginate films remained viable during six months of storage at 4 °C.
