In this study, the emmission of the Bacterial
bioaerosols in the different respiratory system in a neonatal
intensive care unit (ICU). In this study, a six-stage Andersen
impactor was used for the sampling of bioaerosols with a flow rate
of 28.3 L / min. The concentrations obtained from bacterial
bioaerosols ranged between 67 and 423 CFU / m3, with an average
value of 110.13 CFU / m3, which can represent a possible threat to
the health of the workers and neonates in the ICU. The results
indicated than Staphylococcus saprophyticus and Staphylococcus
epidermidis predominated, especially in the fifth and sixth stages,
which means second bronchi and alveoli. While Staphylococcus
was the most prevalent genus, Alloiococcus otitidis, Bacillus
subtiles, Bacillus thuringiensis, Kocuria rosea and Pseudomonas
pseudoalcaligene occurred in the alveoli.
