The present study was aimed to investigate the effects of 3D8 scFv-secreting Probiotic () on growth performance, inflammatory responses, and intestinal microbial flora in chickens. To this end, a total of 14 healthy wild-type chickens were divided into two experimental groups. Each group was orally administrated with a daily dose of 10 colony-forming units (CFU) of 3D8 scFv-producing or wild-type (WT) for 35 days. Administration of /3D8 scFv significantly improved the body weight of chickens when compared to /WT group. The bacterial taxonomic composition of the fecal microbiota was determined by pyrosequencing of 16S rRNA gene amplicons. , and were dominant phyla in two experimental groups. However, in 3D8 treatment groups at genus level, the was highly abundant, being represented by 18.12%. In addition, serum levels of primary cytokines such as IL-6, IL-8, TNF-α, IFN-γ, IL-4, and IGF1 were markedly reduced in the probiotic 3D8 group. In summary, our results indicate that the administration of expressing 3D8 scFv has a modulatory effect on inflammatory responses, improves weight gain while not affecting the common microbial composition of the chicken intestine.
