A survey on indoor and outdoor airborne fungal species distribution in a general hospital located in Shanghai, China

Abstract

Abstract:

Objective To monitor the characteristics of airborne fungi distribution around a Chinese general hospital during Autumn in Shanghai,for scientific basis for clinical prevention and treatment of invasive fungal infections.Methods In a randomly selected general hospital in Shanghai,collecting air samples in 26 indoor and 7 outdoor environments using cyclone-based bioaerosol sampling method and precipitation method,simultaneously.The samples were cultivated,separated and purified on the Sabouraud Agar with chloramphenicol and then identified in molecular technique.All of the data obtained was analyzed statistically.Results The genus Penicillium (24.14%) was prominent in the fungal population structure in indoor environments of the enrolled hospital.In contrast,the genus Cladosporium (34.09%) has the advantage in outdoor environments.The proportion of the genus Penicillium in indoor environments (24.14%) is significantly higher than that in outdoor environments (11.09%).Conclusion Although the level of medicine in Shanghai remains leading position in China and the investigated hospital has been conducting disinfection work according to regulations,there is still a high diversity of fungal species distribution found in the surveyed hospital,which contains common opportunistic pathogenic fungi such as Aspergillus fumigatus,etc.Therefore,continue to reinforce the research on environmental surveillance and infection control of general hospital is of significance.
