Abstract

Abstract: Objective To analyze and monitor the distribution trend of bacterium strains in blood cultures for blood and body fluid specimens in Shanghai Public Health Clinical Center, and to evaluate the false positive / false negative detection results of automated blood culture analyzer. Methods A total of 2 044 blood culture results of different clinical blood and body fluid specimens from January to May, 2011 were collected. Specimens were cultured and identified byMéliès automated blood culture analyzer and identification board. The results were analyzed.Results Different specimens had different positive rates. The puncture fluid specimens had the highest bacterium culture positive rate (38.10%), followed by blood specimens (30.74%). The 231 bacterium strains were isolated. The total positive rate was 11.30%. Coagulase-negative Staphylococcus was the most, accounting for 41.13%, followed by fungi (18.18%) and Staphylococcus aureus (0.87%). Conclusions The bacterium identification and distribution of the blood and body fluidspecimens and the analysis of pathogens and contaminative bacteria will help for guiding the clinical treatment and prevention of sepsis.
