Mohnarin Report 2006-2007:Bacterial Resistant Surveillance among Inpatients of Non-ICU Departments in China / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To investigate the antibacterial resistance of clinical isolates from inpatients of non-ICU departments in China in 2006-2007.METHODS Clinical isolates were collected by member hospitals of Mohnarin according to unified protocol.Bacterial susceptibility testing was carried out using Kirby-Bauer(KB),MIC or E-test methods according to CLSI 2006.The data were analyzed by WHONET 5.4 software.RESULTS A total of 77253 clinical isolates from inpatients of non-ICU departments in Mohnarin member hospitals were collected from Jun 2006 to May 2007,of which Gram-negative bacteria accounted for 53549(69.3%),and Gram-positive cocci for 23704(30.7%).Meticillin-resistant Staphylococcus aureus(MRSA) and coagulase-negative Staphylococcus(MRCNS) strains accounted for 57.6% and 83.3%,respectively.There was no glycopeptide-resistant Staphylococcus to be found,but small part of coagulase-negative Staphylococcus was teicoplanin intermediate or resistant.50.9% Of Enterococcus faecalis and 69.9% of E.faecium strains were resistant to high concentration gentamicin.1.1% And 2.7% of E.faecalis and E.faecium isolates were resistant to vancomycin,0.8% and 2.7% resistant to teicoplanin.There were 9.9% isolates of Streptococcus pneumoniae were penicillin-nonsusceptible.About 34.5% Escherichia coli and 23.5% Klebsiella pneumoniae isolates were ESBLs-producing strains.Isolates of Enterobacteriaceae were still highly sensitive to imipenem and meropenem,the average resistant rate was less than 2%.There were about 70% E.coli isolates resistant to quinolones,and 20-60% of non-fermentative Gram-negative bacilli were resistant to antibacterials.CONCLUSIONS Bacterial resistance is severe in inpatients in our country,and the resistant rates are increasing.More effective measures should be taken
