STAR Protoc. 2023 Sep 15;4(3):102386. doi: 10.1016/j.xpro.2023.102386. Epub 2023 Jun 27.

Abstract

Dysbiosis of the gut microbiome is implicated in the growing burden of non-communicable chronic diseases, including neurodevelopmental disorders, and both preclinical and clinical studies highlight the potential for precision probiotic therapies in their prevention and treatment. Here, we present an optimized protocol for the preparation and administration of Limosilactobacillus reuteri MM4-1A (ATCC-PTA-6475) to adolescent mice. We also describe steps for performing downstream analysis of metataxonomic sequencing data with careful assessment of sex-specific effects on microbiome composition and structure. For complete details on the use and execution of this protocol, please refer to Di Gesù et al.1.
