Abstract:
OBJECTIVE To study the degree and regular of Aspergillus flavus air contamination in hospital.METHODS Some ambient air of different environment in our hospital was taken 5 times in one day of four seasons one year by using centrifugal air sampler,and then cultivated(using eumycete cultural methods),counted and analyzed.RESULTS A.flavus strain was collected in all sampling points in four seasons.The concentration of Aspergillus flavus in six standort was diverse from each other,and the highest was the out-patient clinic with 1238.9 CFU/m3.The concentration of Aspergillus flavus in each division of Medical Department was significant difference during four seasons(P0.05).The difference between internal medicine and external enviroment was significant between the first and the third season(P=0.022,P=0.039),but that of the second and the fouth season was not significant(P=0.022,P=0.624).CONCLUSIONS The contamination of Aspergillus flavus in hospital was severe.So it′s necessary to prevent the Aspergillus flavus infection and enhance the environmental control of susceptible population.
