Particle size of airborn Cryptococcus neoformans in a tower.

ABSTRACT

Nearly 10(6) cells of Cryptococcus neoformans were cultured per g of pigeon droppings in a vacant tower. The air in the tower contained an average of 45 viable cells of C. neoformans per 100 liters: 60% of the cells were less than 4.7 micron in diameter. It is estimated that a human exposed to this atmosphere for 1 h would have 41 cells of c. neoformans deposited in the lungs. Sweeping resulted in the aerosolization of large numbers of cells of C. neoformans from 4.7 to 11 micron in diameter, the number of cells less than 4.7 micron remained relatively constant. One minute after sweeping, 4.4% of viable airborne cells of C. neoformans were less than 1.1 micron in diameter. We believe that this is the first report of isolating such small cells of C. neoformans from a natural site.
