Fungi genus and concentration in the air of onion fields and their opportunistic action related to mycotic keratitis.

The authors determined fungi concentrations and genera from onion fields located in monsoon and nonmonsoon areas of Taiwan, as well as concentrations from a county housing location, which served as the comparison site. The authors explored the relationship(s) among onion harvesting, monsoon characteristics, airborne fungal levels, and mycotic eye infection. Airborne fungal levels in the onion field in the nonmonsoon area were the highest, followed by decreasing levels in the monsoon area and control sites, regardless of the sampling periods.
