Abstract:
OBJECTIVE To analyze the distribution and anti-microbial resistance profile of pathogenic bacteria isolated from hospitalized neonates in Wuhan area.METHODS The strains of bacteria isolated from neonates in hospitalization of Wuhan area from 2006 to 2007 were identified by VITEK 32 automatic bacteria system and antimicrobial susceptibility test was performed by Kirby-Bauer method.The standards of NCCLS issued in 2006 were used to assess the results of antimicrobial susceptibility.RESULTS A total of 3892 strains of bacteria were isolated from 10053 specimens,the positive rate was 38.7%.The Gram-positive cocci and Gram-negative bacilli accounted for 41.0% and 55.2%,respectively.The leading 8 species on the list of isolated strains in the two years accounted for 90.8% of all the isolated strains.MRCNS accounted for 68.6% of coagulase negative staphylococcus,and the MRSA kept a low rate(2.6%) in Staphylococcus aureus.The infection rate of newborn by Enterococcus in blood was remarkably higher than that of the past report in this area.The ?-lactamases-producing Escherichia coli and Klebsiella pneumoniae were accounted for 46.9% and 34.7%,respectively.CONCLUSIONS The distribution and anti-microbial resistance of hospitalized neonates in Wuhan area have regional and group characteristics;it′s necessary to strengthen monitoring the regional epidemic characteristic status and the drug-resistant status of the pathogenic bacteria among neonates.
