FIG 1.

Dysbiosis is associated with enteric pathogen expansion in the gut. Antibiotic treatment causes the depletion of the gut microbiota and a reduction in microbial metabolites. Opportunistic pathogens like Salmonella and C. difficile thrive in such an environment and cause disease. Acute dietary interventions change the metabolic landscape and help to reduce the pathogen load as well as overall pathogenesis of the disease, leading to restored homeostasis. Commensal bacteria are indicated in green, gut pathogens are indicated in red, and purple dots represent gut small molecules like acetate, butyrate, and propionate.
