Abstract: | Sampling was conducted from June 2007 to May 2008 in an enclosed rabbit house to investigate composition and variability of
airborne fungi. Samples were collected using an Andersen-6 sampler, with Sabouraud culture medium as sampling medium. The
results showed that monthly mean concentration was 2.79–5.46 × 103 colony forming unit/m3 air (CFU/m3 air), with the maximum level in October, and the minimum level in January. Within a day, the maximum level occurred at 09:00,
followed by 17:00 and then 13:00. A total of 6,523 fungal colonies, belonging to 17 genera and 36 species, were obtained.
The predominant genera included Cladosporium, Penicillium, Aspergillus and Altemaria, comprising 71.45% of the colony count. The obtained fungi of the year were mainly centralized in the stage D of the sampler
(2.0–3.0 μm), accounting for 37.8% of the colonies. The minimum value occurred at stage F (<0.65 μm), accounting for 1.10%
of the colonies. |
