Analysis about blood samples of pathogenic bacteria separated and identified

Objective:To analyze pathogenic bacteria and the types of its drug sensitivity which was isolated in the blood culture experiments in our hospital during January 2010 to June 2011.Methods:The blood samples from patients were cultured through the blood culture,positive instrument strains was given drug sensitive analysis,the drug sensitivity test and identification of strains was made by bacteria identification system of the MicroScan walkAway-40.Results:In 2 960 blood culture samples,322 cases were isolated.There were 115 plants for gram negative bacteria,the separating rate was 3.9%(115/2 960);172 plants for bacterium of positive of bacteria,the separating rate was 5.8%(172/2 960);35 cases for fungi,the rate was 1.2%(35/2 960) .The separation of pathogenic bacteria were staphylococcus aureus,solidify enzyme negative staphylococcus aureus,pneumonia crayresearch bacteria,escherichia coli and multiple fungus primarily.In the bacterium of positive of bacteria were found vancomycin resistant strains,gram-negative bacterium of common carbon penicillium kind was highly sensitive to antibiotics.Conclusion:Gram-negative bacteria infection of the highest proportion,bacterium of positive of bacteria accounts for poorer;Separation of the common bacteria cultivation income for clinical common antibiotics sensitivity low existence.
