Abstract:
Objective To study the genotypes of ESBL-producing Enterobacteriaceae in Xi'an city.Methods Totally 125 ESBL-producing Enterobacteriaceae strains were randomly selected from five hospitals of Xi'an City,and TEM-type,SHV-type and CTX-M-type ESBL genes were amplified by PCR.Results Among the 125 ESBL-producing Enterobacteriaceae strains,TEM-type ESBL genes were amplified from 33 strains,SHV-type ESBL genes were amplified from 26 strains,CTX-M-type ESBL genes were amplified from 49 strains,and two or more type ESBL genes were amplified from 22 strains.Conclusion CTX-M-type ESBL are prevalent in ESBL-producing Enterbacteriaceae in Xi'an City.
