This study identifies that the K-antigen of Porphyromonas gingivalis coats outer membrane vesicles, not the bacterial cell surface, and shows its presence in subgingival plaque from periodontal patients.

This study shows that Porphyromonas gingivalis and other oral bacteria can inhibit SARS-CoV-2 infection through cytotoxicity and unknown mechanisms, with individual variation in oral microbiome activity.

This study characterizes PorX, a response regulator in the Type-IX secretion system, revealing its unique enzymatic activity and zinc-dependent dimerization, with implications for virulence factor secretion in bacterial pathogens.
