Gut microbiota and serum metabolomics in children with human parainfluenza virus infection

Objective

Based on gut microbiota and serum untargeted metabolomics analyses, this study investigated changes in gut microbiota structure and serum metabolic profiles in children infected with human parainfluenza virus (HPIV). By integrating multi-omics data, we aimed to explore interactions between gut dysbiosis and serum metabolic disorders, and their potential roles in HPIV pathogenesis, to provide preliminary evidence for microbiota--targeted and metabolic intervention strategies.
