Study gives more insight into bacterium's protective role in chronic rhinosinusitis

A rise in chronic rhinosinusitis (CRS) in Japan has prompted a study on the role of the nasal microbiome in the development of the condition. Researchers collected nasal swabs from 143 subjects and found significant differences in microbiome diversity between those with CRS and healthy control subjects. The composition of the microbiome also differed significantly between eosinophilic (ECRS) and non-eosinophilic (non-ECRS) CRS, with the bacterium Fusobacterium nucleatum being less abundant in ECRS patients.
