Fungal biodiversity in indoor environments in Havana, Cuba

摘要

A study was made of the indoor mycobi-ota in a range of public and private buildings (libraries, museums, laboratories and offices, warehouses, homes and a school) in the city of Havana (Cuba). Culturable airborne fungi were sampled using a slit-to-agar impactor (Chirana aeroscope). High levels of contamination were recorded, with more than 700 colony-forming units per cubic metre of air in 85% of the buildings sampled, and more than 1,000 in 55% of buildings. Of the 28 genera and 31 species identified, the most common were Aspergillm flavus, Aspergillus niger, Penicillium citrinum, Cladospo-rium cladosporioid.es and Cladosporium sphaerosper-mum. Genus and species diversity was analysed, and new findings were obtained regarding Cuba's atmospheric ecosystem.
