Dynamic airborne mycobiome in the metropolitan city transit system is driven by seasonality and station type.

ABSTRACT: Subway transit systems serve as the primary transportation mode in metropolitan areas. The quality of the airway in transit plays a crucial role in human health as commuters and workers are exposed to microbes transmitted from passengers and circulated within built environments. The diversity and dynamics of bacterial microbiome in these environments have been relatively well studied. However, the fungal communities remain poorly investigated. In this study, we conducted a year-long comprehensive investigation of the mycobiomes within the world's second largest subway system and analyzed the seasonal dynamics of fungal composition across intercity hub stations, urban hub stations, and suburban stations. We found a high diversity of the subway mycobiome that varied seasonally and was influe
