Mice models serve as a valuable tool to study microbiome-immune system interactions. While the use of germ-free mice may represent the gold-standard method, antibiotic-based microbiome depletion provides a more cost-efficient and feasible system. The protocol here in presented provides a mild antimicrobial regime to deplete basal microbiota in 8-week-old C57BL/6 mice, aiming to ensure reproducibility in microbiota studies.

Background: Methylglyoxal (MGO), a highly reactive precursor of advanced glycation end products (AGEs), is endogenously produced and prevalent in various ultra-processed foods. MGO has emerged as a significant precursor implicated in the pathogenesis of type 2 diabetes and neurodegenerative diseases. To date, the effects of dietary MGO on the intestine have been limited explored.

A major health and financial burden in the chicken sector is salmonella infection. It is difficult to create an oral vaccination that can provide strong intestinal mucosal immunity in birds, particularly cross-protection against several Salmonella serotypes. As a result, the poultry industry needs a powerful oral vaccination platform that uses live bacterial vectors to prevent various Salmonella serotypes.

: This work investigated the effect of bacterial nanocellulose (BNC) alone or with chemisorbed chlorhexidine or povidone-iodine on post-tooth extraction repair in rats undergoing bisphosphonate therapy. : Forty Wistar rats were treated with zoledronic acid, subjected to tooth extractions and allocated into groups according to the material inserted in the post-extraction socket: (1) BNC ( = 10); (2) BNC/Iodine ( = 10); (3) BNC/Chlorhex ( = 10); (4) Control ( = 10). Maxillae were dissected and macro- and microscopically analyzed.
