Resumo
The changes related to health environments have been the subject of many studies,
because of the severity and negative impact that can compromise the recovery of the
patient and the well-being of people in local and even the visitors of hospitalized
people. This work aimed to evaluate the presence of microorganisms in bioaerosols in
a medium-sized hospital in the northwest region of São Paulo, in two restricted
locations: intensive care unit (ICU) and Central for Material and Sterilization (CMS). Air
samples were collected at three strategic points, once a month, for six consecutive
months comprising two different times: from 7 am to 7 pm and from 7 pm to 7 am of
the following day. For fungal collection, the spontaneous sedimentation method was
used, by Petri dishes placed in predetermined locations. The plates were closed,
stored in an appropriate place and transported to the microbiology laboratory of
Faculdade Brasil, in the city of Fernandópolis, where they were analyzed. For the
identification of fungi, macro and microscopic morphological characteristics were used,
as well as conventional biochemical methods. The colony-forming units were identified
and accounted for, being analyzed statistically, through analysis of variance (ANOVA)
and cluster analysis by hierarchical method. The following genera and species of fungi
were found: Aspergillus fumigatus, Aspergillus niger, Candida albicans, Cladosporium
spp, Curvularia spp, Fusarium spp, Penicillium spp, Rhizopus spp and Mucor spp. It
was found that the daytime operation period is more prone to infections, since most of
the colony-forming units developed between the hours of 7 am to 7 pm, which
coincides with a greater presence of people in the place. The ICU was the place with
the highest presence of microorganisms,
