PP-045 Pathophysiology of cryptosporidiosis in immunosuppressed Balb/c and C57bl/6 mice models

examine the epidemiology and microbiology of bacteremia in adult patients who hospitalized in the infectious disease department of First Hospital, Jilin University. Methods: A retrospective observational study involving 87 adult septicemia patients and 113 blood cultures (Oct 2010-Apr 2011) of septicemia cases was performed in the infectious disease department, and the epidemiology and microbiology were analysised. Results: Among these blood cultures, 38 (33.6%) were pathogens positive. Most common pathogen was Escherichia coli 11 (40.7%), then Staphylococcus 5 (18.5%). Urinary tract infections (41.4%, 36/87) were most common in these patients. Liver abscess (10.7%, 9/87) were risk factor of septicemia too. Conclusions: Gram-negative bacterias is main pathogens of septicemia in our department. Infections such as urinary tract infections, liver abscess, and so on, should be pay more attention.
