  • Airborne bacteria and fungi in different indoor environments: levels and dose rates
    Publication . Paciência, I.; Madureira, J.; Cavaleiro Rufo, J.; Aguiar, L.; Teixeira, João Paulo; Pinto, M.; Moreira, A.; de Oliveira Fernandes, E.
    The study aimed to: (i) quantify bacteria and fungi concentrations in 4 indoor environments; (ii) identify the recovered fungi; (iii) assess the impact of outdoor bacteria and fungi indoors; and (iv) estimate bacterial and fungal inhalation dose rates in children and elderly. Air samples were collected from 20 primary schools, 68 homes, 9 child day-care centres and 22 elderly care centres, with a microbiological air sampler using TSA and MEA culture media.

  • Bacterial and fungal exposure in schools may influence asthma and allergy in children
    Publication . Cavaleiro Rufo, João; Madureira, J.; Paciência, I.; Aguiar, L.; Delgado, L.; Teixeira, J.P.; de Oliveira Fernandes, E.; Moreira, A.
    Development of allergic diseases may be regulated by microbial exposure. Children spend a lot of their time in schools, under an extensive diversity of biological agents, such as bacteria and fungi. This study aimed to characterize indoor air microbiological exposure in schools as a predictor of allergic sensitization and asthma in children.

  • Identification and Levels of Airborne Fungi in Portuguese Primary Schools
    Publication . Madureira, J; Pereira, C.; Paciência, I.; Teixeira, João Paulo; de Oliveira Fernandes, E.
    Several studies found associations between exposure to airborne fungi and allergy, infection, or irritation. This study aimed to characterize airborne fungi populations present in public primary schools in Porto, Portugal, during winter through quantification and identification procedures. Fungal concentration levels and identification were obtained in a total of 73 classrooms. The AirIdeal portable air sampler was used in combination with chloramphenicol malt extract agar. Results showed a wide range of indoor fungi levels, with indoor concentrations higher than outdoors. The most prevalent fungi found indoors were Penicillium sp. (>70%) and Cladosporium sp. As evidence indicates that indoor fungal exposures plays a role in asthma clinical status, these results may contribute to (1) promoting and implementing public health prevention programs and (2) formulating recommendations aimed at providing healthier school environments.
