Fungal populations in the bedroom dust of children in Havana, Cuba, and its relationship with environmental conditions

The study of the fungal community composition in house dust is useful to assess accumulative exposure fungi indoor environments. objective this research was characterize diversity and its association with environmental conditions bedrooms. For this, collected from 41 bedrooms children between ages 8 9 a family history asthma, residents Havana, Cuba. content each sample determined by two methods: plate culture malt extract agar direct microscopy.

Through microscopy, 10 2311 fragments hyphae spores corresponding mainly Cladosporium, Coprinus, Curvularia, Aspergillus/Penicillium, Xylariaceae, Periconia were identified. culture, 0–208 CFU quantified, where Aspergillus, Penicillium predominated. culturability evidenced differences quantification both methods. A positive relationship found type cleaning furniture, presence trees front bedroom, relative humidity, temperature, air conditioning, natural ventilation specific spore types genera. use different identification methods allowed detect greater residences evaluated. Monitoring these allergens childhood can help prevent sensitization allergic child, development other respiratory diseases.
