“…Some authors used the passive sedimentation technique to collect air samples (Melo et al, 2009;Lobato et al, 2009;Sales et al, 2011;Awosika et al, 2012;Okten & Asa, 2012;Pantoja et al, 2012;Aboul-Nasr et al, 2014;Gonçalves et al, 2018;Calumby et al, 2019;Souza et al, 2019). Open Petri dishes were exposed to air for between 10 and 30 min at a height of 80 to 150 cm from the floor.…”

“…Penicillium prevailed among the isolates identified by Brazilian authors such as Melo et al (2009), who analyzed PICU and NICU indoor air in Pouso Alegre, MG; Calumby et al (2019), who isolated and identified the anemophilous fungal microbiota present in the ICU of a hospital in Maceió, AL; and Gonçalves et al (2018), who studied the indoor air from a university hospital in Pelotas, RS. Calumby et al (2019) reported that Cladosporium constituted 28.1% of total recovered fungi.…”

Invasive fungal infection is an important cause of mortality and morbidity in neonates, especially in low-birthweight neonates. The contribution of fungi in the indoor air to the incidence of mucocutaneous colonization and to the risk of invasive fungal infection in this population is uncertain. This review aimed to identify and to summarize the best available evidence on the fungal contamination in the indoor air of critical hospital areas with an emphasis on pediatric/neonatal ICUs. Publications from 2005 to 2019 were searched in the databases Scientific Electronic Library Online (SciELO), US

“…Studies developed by Tong et al, (2017) and Gonçalves et al, (2017) on fungal dispersion and hospital environments indicated that events of disinfection, ventilation and personnel transit are determining factors for the presence of anemophilus fungi in the environment. Of all factors, human presence contributes significantly to the fungal diversity observed in indoor air in hospitals.…”

Fungi are opportunistic organisms with wide geographical distribution and can also be found in the hospital environment. These microorganisms can cause infections, especially in immunocompromised patients. The aim of this study was to evaluate airborne fungal contamination in two neonatal intensive care units (ICU) of a public hospital before and after cleaning. The technique of Petri dishes exposure containing Sabouraud agar with 50mg/L chloramphenicol was used for sample collection. Air conditioning filters were also sampled using a sterile swab for fungal collection. The identification of fungal isolates was performed by observing macroscopic and microscopic structures. A total of 1305 colony forming units was isolated, where: 718 (55.0%) were isolated before neonatal ICU cleaning and 587 (45.0%) after cleaning. Forty-two species belonging to 24 genera were identified, being Cladosporium cladosporioides, Penicillium aurantiogriseum and Aspergillus oryzae the most frequent species in the analyzed samples. The presence of pathogenic fungi in ICUs demonstrates the need for constant monitoring of indoor air quality in order to better control airborne contamination in hospital environments.

Background and Objectives: It is very common that hospital environment is colonised by microorganisms. This colonisation is a potential threat for hospitalised patients, especially in highrisk services. Quantification of microorganisms from surfaces is an important strategy to control the hospital infection. Materials and Methods: Total 70 samples were collected and seeded in the Mueller Hinton and Sabouraud Agar culture media. Media cultures in Petri dishes were incubated and microbial growth was quantified (CFU/cm 2). Bacteria cultures were characterised by Gram stain. Fungal cultures were submitted for micromorphological evaluation and CHROMagar™ incubation. Results: Bacterial population higher than 250 CFU/cm 2 was found in 11 out of 70 samples. Fungi were found in 3 out of 70 samples. Common manipulation surfaces as water drinking unit, shelf and water tap presented the highest contamination rates. Bacterial cultures (n= 95) showed mostly the presence of Gram-negative bacteria (81%). In addition, regarding the fungal cultures (n= 129) mostly filamentous fungi (72%), from Aspergillus genera were obtained.
