Abstract:
Objective To analyze the clinical features,etiology and antibiotics-resistance in purulent meningitis cases identified in our hospital during the recent 5 years.Methods Clinical data were collected and the etiology and antibiotics-resistance were analyzed in 36 children with purulent meningitis during Jan 2007 to Oct 2011,and all cases were identified by a positive cerebrospinal fluid culture.Results There were 2 267 cerebrospinal fluid samples cultured and only 36 samples showed positive results and the rate was 1.6％,and 27 strains (75.0％,27/36) were Gram positive cocco bacteria.The most common bacterium was coagulase negative Staphylococcus and the ratio was 50.0％ (18/36),followed by Escherichia coli ( 13.9％,5/36),Streptococcus pneumonia ( 11.1％,4/36) and Staphylococcus aureus ( 8.3％,3/36).Drug sensitive test showed that 95.2％ of the Staphylococcus was β-lactamase positive and resistant to penicillin,and 33.3％ were sensitive to oxacillin.The death rate was 13.9％ (5/36).Conclusion Staphylococcus,Escherichia coli and Streptococcus pneumonia are the top three pathogens causing purulent meningitis in children in our hospital,and clinicians should choose antibiotics according to the result of drug sensitive test.
