Investigation of the effects of three incubation temperature on the density and composition of airborne fungi in an indoor and outdoor space of hospital provided that incubationTemperature had effect on airborne fungi remarkably.Abstract:
Fungi are one of the bioaerosols in indoor air of hospitals. They have adverse effects on staff and patients. The aim of this study was to investigate the effects of three incubation temperature on the density and composition of airborne fungi in an indoor and outdoor space of hospital. Sabouraud dextrose agar was used for culture the fungi. For improvement of aseptic properties, chloramphenicol was added to this medium. The density of airborne fungi was less than 282 CFU/m3. The highest density was detected in emergency room and the lowest of them was in neonatal intensive care unit (NICU) and operation room (OR). Results showed that fungi levels at 25 °C were higher than 37 and 15 °C (p = 0.006). In addition, ten different genera of fungi were identified in all departments. The predominant fungi were Fusarium spp., Penicillium spp., Paecilomyces spp., and Aspergillus niger. Moreover, the density and trend of distribution of Fusaruim spp. in the indoor space was directivity to outdoor space by ventilation system. The present study has provided that incubation temperature had effect on airborne fungi remarkably. We are suggested that more studies would be conducted on incubation temperature and other ambient factors on airborne fungi.read more

Influence of air supply velocity and room temperature conditions on bioaerosols distribution in a class I operating room
TL;DR: In this paper, the authors used the renormalization group (RNG) k-e model as a turbulence model to simulate a full-scale operating room and found that an increase in the air supply velocity would increase the dispersion of bioaerosols particles.
