Abstract
In recent decades, the contamination of the atmosphere has occupied a prominent
place causing countless harm, making it a public health problem which
jeopardises in a serious way the hospital environment, bringing a potential risk of
hospital infection (HI). The aim of the study was to identify and classify hospital
fungal contaminants in units of high complexity. The assessment of air quality
was carried out in four categories of environment: High Complexity Intensive
Care Adult Unit (AICU), Newborn (NICU), hallways and corridors and external
area. The monitoring of these environments was conducted in the morning and
afternoon, the air filters were removed and transferred to plates with culture
media BDA and incubated at 28°C, isolated and identified. Ten genera of
filamentous fungi, pathogenic and toxigenic were found. It was found that, in the
afternoon and in the morning, the contamination was significantly lower in
AICU (23.3 CFU/m3), with 55.3 CFU/m3 in NICU. In none of the environments
studied, the average concentration of filamentous fungi exceeded the maximum
recommended by Resolution N°. 09 of the National Agency for Sanitary
Vigilance of 750 CFU/m3.
