This study compares oral and gut microbiomes in HIV patients and finds oral bacteria like Veillonella parvula contribute to systemic inflammation through epithelial barrier disruption and monocyte activation.

The paper develops an ex vivo gut mucosal explant assay to measure HIV susceptibility, showing methamphetamine increases susceptibility.

This study identifies gut barrier integrity biomarkers linked to inflammation and disease severity in hospitalized COVID-19 patients using plasma biomarker analysis and a random forest model.

The paper investigates the association between gut microbiome composition and poliovirus vaccine seroconversion in children in the Democratic Republic of the Congo, finding that early presence of Campylobacter and Veillonella is linked to lower seroconversion rates.
