Abstract:
OBJECTIVE To investigate the current status,the clinical features and the pathogens of invasive fungal infections in hospital in order to provide clinical treatment based on identification and susceptibility test.METHODS The fungus-cultured positive cases among the discharged patients from Jan 2004 to Nov 2006,were analyzed according to their definite diagnosis of invasive fungal infections under the items,such as the patients age,underlying disease,sample,strain,and species distribution.RESULTS The rates of invasive fungal infections were 4.26%.There were 2221 fungus strains belonged to 8 species in all samples;the patients age was 7-96 years with 2 kinds of various underlying diseases;the age of 2221 cases was 60 years old,mainly senile patients with various diseases accounted for 68.29%.Lower respiratory tract was the most frequent infection site.The main pathogens of invasive fungal infections were Candida spp(93.38%).Strains of Candida albicans were the most frequent organism isolated accounted for 66.19% of all the isolates.C.glabrata,C.krusei and C.tropicalis accounted for 9.19%,8.10% and 4.50%,respectively,the others accounted for only 6.32%.The main infected sites were lower respirtory tract,urinary tract and digestive tract.CONCLUSIONS Candida spp are still the main pathogens of invasive fungal infections.The epidemiological properties of invasive fungal infections is changed.The incidence of non-C.albicans and the Aspergillus strains that arouse invasive infections is increasing recently.
