Effect of microencapsulated Fiber2-displaying probiotics loaded with inulin nanoparticles on immunity against fowl adenovirus serotype 4 in chickens.

ABSTRACT: In this study, phthalate inulin nanoparticles (PINs) were chemically modified and characterized. The internalization of PINs into the probiotic E. faecalis, which delivering Fiber2 protein of fowl adenovirus serotype 4 (FAdV-4), was investigated. The expression of the Fiber2 protein in E. faecalis was detected using western blot analysis. To protect recombinant E. faecalis from degradation of in the gastric acid environment, sodium alginate was used to encapsulate the bacteria. The survival ratio and release of E. faecalis in simulated gastrointestinal fluid was assessed. Oral administration of microencapsulated E. faecalis loaded with PINs (Micro-E/Fiber2-PINs) or inulin (Micro-E/Fiber2-inulin) was conducted, followed by an experimental challenge with FAdV-4 in chickens to evaluate immune
