Introduction. Healthcare workers are at risk of occupational infections and some procedures, such as bronchoscopies, are known to increase this risk. Therefore, this study aims to assess the microbial load and composition of aerosols generated by patients during bronchoscopy in order to quantify the occupational risk of professionals. Methodology. Aerosol samples were collected during routine bronchoscopy practice in two hospitals using personal samplers placed on the practitioner's clothing. Samples were cultured in different culture media, and detection of respiratory viruses (SARS-CoV-2, Influenza A/B and RSV) was performed by RT-PCR. Results. Twenty-nine samples were collected from which a total of 234 isolates were obtained, 207 of which correspond to bacterial species and 27 to fungal species. The most abundant bacterial genera are Micrococcus, Staphylococcus and Bacillus and the fungal genera are Aspergillus, Talaromyces, Cladosporium and Trichoderma. A total of 8 SARS-CoV-2 positive samples were also detected. Conclusions. Culturable bacteria from the oral, nasal and lung microbiota are aerosolised during bronchoscopy and could be inhaled by medical staff. The possible presence of pathogens in these aerosols could represent a risk of occupational infection.
