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.

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.

The paper analyzes HIV-1 entry kinetics across 257 isolates, identifying single-residue determinants and showing cooperative sequential roles of co-receptor engagement and gp41 function in entry.
