Abstract:

Objective

To investigate the drug-resistance and distribution of isolated Escherichia coli dynamically, and to provide evidence to improve the clinical experience of drug application and infections control measures.

Methods

Total of 224 stains of Escherichia coli were collected from January 1st, 2015 to March 31st, 2015, whose drug-resistance to 19 antibacterials and the clinical distribution were analyzed by WHONET 5.6.

Results

Drug-resistance rates of 224 stains of Escherichia coli to ampicillin, cefazolin, ciprofloxacin, cefuroxime, levofloxacin, cefotaxime, gentamicin, aztreonam, cefepime, tobramycin, ceftazidime, amoxicillin/clavulanate, cefoxitin, cefoperazone/sulbactam, amikacin, piperacillin/tazobactam, ertapenem, meropenem and imipenem were 84.4% (189 strains), 60.3% (135 strains), 57.1% (128 strains), 57.1% (128 strains), 53.1% (119 strains), 52.7% (118 strains), 45.1% (101 strains), 42.0% (94 strains), 41.1% (92 strains), 37.1% (83 strains), 26.3% (59 strains), 15.2% (34 strains), 12.1% (27 strains), 6.7% (15 strains), 4.0% (9 strains), 4.0% (9 strains), 1.3% (3 strains), 1.3% (3 strains) and 1.3% (3 strains). About 59.4% (133 strains) Escherichia coli were collected from urine specimens, and 17.0% (38 strains) were from sputum specimens; 26.8% (60 strains) were distributed in Urinary Department of Internal Medicine Ward.

Conclusions

Carbapenem-resistant Escherichia coli has been found in our hospital. Dynamic monitoring of the drug-resistance and distribution of the Escherichia coli could improve the accuracy of empirical medication.
