Aim of this paper is to present the results of a survey, performed in a teaching hospital of Rome, in order to evaluate the fungal air pollution of operating theatres (OTs) in which also high risk patients underwent an operation. The study was performed in 14 OTs. In each OT, 9 air samples were collected, using an active sampler SAS-PBI. Rodac plates with Sabouraud cloramphenicol and nutrient agar were used; the CFU were counted after incubation for 48h at 37 . Eight (57%) OTs showed at least one sample positive for Aspergillus. 12 (9,5%) of the 126 samples collected were positive. 33,4% of positive samples were collected near the air conditioning system outlet (A. fumigatus, A. flavus, A. niger) and a further 33,4% near the surgical table (A. niger, A fumigatus, A. nidulans, A. flavus). The remaining strains were isolated away from such critical places. All Aspergilli isolated were thermo-resistant.

Abstract
Aim of this paper is to present the results of a survey, performed in a teaching hospital of Rome, in order to evaluate the fungal air pollution of operating theatres (OTs) in which also high risk patients underwent an operation. The study was performed in 14 OTs. In each OT, 9 air samples were collected, using an active sampler SAS-PBI. Rodac plates with Sabouraud cloramphenicol and nutrient agar were used; the CFU were counted after incubation for 48h at 37 . Eight (57%) OTs showed at least one sample positive for Aspergillus. 12 (9,5%) of the 126 samples collected were positive. 33,4% of positive samples were collected near the air conditioning system outlet (A. fumigatus, A. flavus, A. niger) and a further 33,4% near the surgical table (A. niger, A fumigatus, A. nidulans, A. flavus). The remaining strains were isolated away from such critical places. All Aspergilli isolated were thermo-resistant.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
