Strains Isolated from Mice Intestinal Tract: Molecular Characterization and Antagonistic Activity against Food-Borne Pathogens.

Considering the objectives of "One Health" and the Sustainable development Goals "Good health and well-being" for the development of effective strategies to apply against bacterial resistance, food safety dangers, and zoonosis risks, this project explored the isolation and identification of strains from the intestinal tract of recently weaned mice; as well as the assessment of antibacterial activity against clinical and zoonotic pathogens. For molecular identification, 16S rRNA gene-specific primers were used and, via BLAST-NCBI, 16 , one and one strains were identified and registered in GenBank after the confirmation of their identity percentage and the phylogenetic analysis of the 16 strains and their association with . The 18 isolated strains showed antibacterial activity during agar diffusion tests against ATCC 15313, enteropathogenic O103, and ATCC 49943.

Encapsulation of ATCC 8014 and ATCC 8042 in a freeze-dried alginate-gum arabic system and its testing under gastrointestinal conditions.

The aim of this study was to investigate the viability of ATCC 8042 and ATCC 8014 in a freeze-dried capsules system prepared with sodium alginate and gum arabic using the extrusion technique. The capsules made with alginate 2% (w/v)/gum arabic 2% (w/v) showed higher hardness (7.12 ± 0.
