Abstract Bacteroides Fragilis (BF) is a symbiotic bacterium in human intestinal tract, and also an anaerobic bacterium with relatively high positive rate in clinical work. 12 strains of anaerobic bacteria isolated from 8 cancer patients from June 2020 to December 2021 were identified as Bacteroides Fragilis by MALDI-TOF technique.Analysis of medical records showed that: five patients suffered with colorectal cancer; surgery is the most common predisposing factor for Bacteroides fragilis bloodstream infetion(4/8);Imipenem and cilastatin sodium was seclected for treatment in 4 patients,and the other 4 patients took other different types of antibiotics.All patients were effectively treated with antibiotics, got controll of fever and infection.It turned to be negative for the subsequent blood culture reexamination.This cases analysis of bloodstream infection caused by bacteroides fragilis in cancer patients, is to provide evidence for microbiology detection and clinical diagnosis and treatment .
