Abstract
A descriptive study was developed to monitor air fungal contamination in one
Portuguese maternity. Sixty air samples were collected through impaction
method. Air sampling was performed in food storage facilities, kitchen, food
plating, canteen, pharmacy, sterilization areas, genecology wards, intensive care
unit, operating rooms, urgency and also, outside premises, since this was the
place regarded as reference. Besides air samples, forty three samples were
collected by swabbing the surfaces using a 10 by 10 cm square stencil.
Simultaneously, temperature, relative humidity and particles counting (PM10)
were registered. Twenty three species of fungi were identified in air, being the
two most commonly isolated the genera Penicillium (41,5%) and Cladosporium
(28,4%). Regarding yeasts, only Rhodotorula sp. (45,2%), Trichosporon
mucoides (51,6%) and Cryptococcus neoformans (3,2%) were found. Thirteen
species of fungi were identified in surfaces, being the most frequent the
Penicillium genus (91,6%). Concerning yeasts found in surfaces, four species
were identified being Rhodotorula sp. (29,1%) the most frequent.
There was no coincidence between prevailing genera indoors and outside
premises. Moreover, some places presented fungal species different from the
ones isolated outside. In the inside environment, Aspergillus species were
isolated in air and surfaces. There was no significant relationship (p>0,05)
between fungal contamination and the studied environmental variables.
Keywords: air, surfaces, fungal contamination, environmental variables,
maternity.
