Aspergillus
versicolor was aerosolized for 75 minutes and 6 samples were collected at 30 minute intervals for 90 minutes following the aerosolization (2 samples per time period).
Each air

The plates
were then counted to determine the number
of colony forming units (CFU), those that are able to reproduce
