Abstract: The present invention provides compositions and methods using one or more strains of Akkermansia muciniphila. Particularly, the compositions comprising one or more A. muciniphila strains may be used to add in reduction in obesity and in methods of recolonizing the flora of the gut of a subject, as described in the disclosure.

Abstract: The present disclosure provides methods and systems for genetically altering and screening Akkermansia bacteria, including Akkermansia muciniphila. The methods also provide genetically altered bacteria, libraries of genetically altered bacteria and use of such bacteria for treatment of diseases.

Abstract: Embodiments of the present disclosure relate generally to the genetic analysis of intractable microbes. More particularly, the present disclosure provides materials and methods that incorporate chemical mutagenesis, phenotypic selection, suppression analysis, and genomic sequencing-based mutational mapping, to identify novel genetic regulators in previously intractable organisms, such as microbes that constitute the human microbiome. Given the paucity of experimental tools to manipulate bacterial genomes, there is a need for improved methods for determining how microbial communities assemble and influence human and environmental health.
