Correlation of gut microbial compositions to the development of Kawasaki disease vasculitis in children.

Here, we hypothesize that dysbiotic gut microbiota might contribute to the development of Kawasaki disease (KD), a pediatric disease with unknown etiology. This is the second report on gut microbiota composition in KD patients. 16S amplicon sequencing was performed on fecal DNA samples and revealed predominance of bacterial pathogens, such as , ,  and , in the gut of KD patients, but absent or suppressed after immunoglobulin/antibiotics therapy.
