Resumen:
Airborne fungi have the ability to release into the environment their reproductive structures
called spores, which are transported by the air and when they find a suitable area, they deposit,
colonize, and reproduce. Given the facts, this study aimed to analyze the air quality and research
the fungal microbiota of a hemodialysis clinic located in Rio Grande do Norte. For this, the
spontaneous sedimentation method was used for the deposition of these spores in Petri dishes
with Sabouraud dextrose Agar culture medium, which were exposed in the places for 15
minutes, and incubated at 28°C for up to 14 days. After this period, colonies were counted,
picked and identified macro and microscopically using the microculture technique. With the
identification it was possible to notice the presence of the filamentous fungi Cladosporium spp.
(42.85%) which had the highest prevalence, Aspergillus spp. (7.14%), Bipolaris spp. (3.54%),
and Mycelia sterilia (3.57%), in addition to a number of yeasts (42.85%) whose genera were
not identified. In addition, an equation was used to measure air quality, and it can be seen that
the maximum amount of CFU/m3 found and the I/E ratio were within the limits established by
ANVISA. Therefore, it is possible to conclude that the conduct adopted by the institution is
leading to good results in terms of indoor air quality.
