Nanoliposome-encapsulated Phenolic Rich Fraction From Alcea Rosea as a Dietary Phytobiotic in Mice Challenged by Escherichia Coli
Abstract Background: This research was performed to evaluate the antibacterial and health-promoting potentials of the nanoliposome-encapsulated phenolic rich fraction (PRF) from Alcea rosea leaves as a dietary phytobiotic in mice challenged by enteropathogenic Escherichia coli (E. coil; O157: H7). Results: The overall results demonstrated that the nanoliposome-loaded PRF contained gallic acid, salicylic acid, pyrogallol, cinnamic acid, catechin, naringin, ferulic acid. The E. coil challenge in mice impaired the weight gain, food intake, liver enzymes, lipid peroxidation, morphometric characteristics of the ileum, up-regulated the inflammatory genes (COX2, iNOS), down-regulated the antioxidant-related genes (SOD and GPx) and increased the population of E. coil in the ileum. The dietary inclusion of nonencapsulated PRF and nanoliposome-encapsulated PRF at the concentration of 10 mg TPC/kg BW/day improved these parameters however the nanoliposome-encapsulated PRF appeared to be more effective as compared to nonencapsulated PRF in improving the health parameters in mice. Conclusion: Consequently, the nanoliposome-encapsulated PRF could play a critical role as a promising phytobiotic against E. coil infection in mice..
