Genomic And Culturomic Analysis Of Gut Microbiota Function And Salmonella Enterica Expansion, Gavin Fenske

Electronic Theses and Dissertations

Enteric bacteria that are resident in the hindgut of mammals are critical in immune development, digestion, and colonization resistance against pathogens. One of the major pathogens that gut commensals provide resistance against is Salmonella enterica, a major foodborne pathogen capable of infecting almost every warm-blooded animal. Given the interplay between pathogens and commensals in the gut lumen, the gut microbiota of pigs was studied by combining two disparate techniques: shotgun metagenomics and high throughput culturomics. Metagenomics readily identifies major taxa present in samples and can give an estimation to total genetic catalogue from an environment. However, many rare or …
