Nanotechnology is also playing a role in enhancing the delivery of probiotics. Delivery of beneficial microorganisms that increase nourishment through natural biological processes has also benefited from nanoen-capsulation technology. Examples of favorable bacteria used in probiotics are Lactobacillus salivarius, Lactobacillus acidophilus, Saccharomyces boulardii, Saccharomyces thermophilus and Bifidobacterium species that aid the digestion of food, increase energy storage and fermentation of sugars, help prevent tumor formation, stimulate the production and release of vitamins and antibiotics, and inhibit the development of pathogenic conditions such as those associated with infections, inflammation, and heart disease [22].

It was shown that a probiotic Escherichia coli strain Nissle 1917 forms stable biofilms on silicone surfaces particularly after modification with a biphenyl mannoside derivative. These biofilms were able to reduce the colonization by pathogenic Enterococcus faecalis for 11 days [65]. In another study, a Lactococcus lactis strain was genetically modified to produce the FimH virulence factor of uropathogenic Escherichia coli (UPEC) on the cell surface. This strain was able to form robust biofilms in abiotic surfaces and survived in the mice bladder. The protective effect against UPEC was demonstrated using a urinary tract infection (UTI) mouse model [66]. It has been shown in vivo and in vitro that Lactobacillus salivarius and its bacteriocin (salivaricin LHM) may be used as therapeutic and prophylactic agents against Pseudomonas aeruginosa infections of the urinary tract [64]. Although these studies did not address the specific case of urological stents, the use of nonpathogenic bacteria to manage biofilm infection on these devices seems a promising strategy given the experimental conditions that were used.
