Genotyping of E.coli and klebsieua pneumoniae producing extended spectrum ?-lactamases in Jilin area of China / 基础医学与临床

ABSTRACT

Objective To genotype strains producing ESBLs in Escherichia coil and Klebsieua pneumoniae to provide references for the clinical application of drugs.Methods PCR was used to determine the genotype of the ESBLs.Results The percentage of TEM type,SHV type and NO-TEM-NO-SHV type in Escheroichia coil was 80.4%,7.8% and 11.8%,in Klebsieua pneumoniae was 78.1%,71.9% and 25.0%.Most of Klebsieua pneumoniae produced more than two Extended Spectrum ?-lactamases.Conclusion The difference in the distribution of genotypes in different regions is confirmed.
