Abstract:
OBJECTIVE To investigate the drug-resistance of AmpC enzyme derepressing Enterobacter cloacae isolated from patients of respiratory department.METHODS Totally 364 strains of E.cloacae(162 strains from respiration department) collected from Jan 2001 to Dec 2006 were investigated to know their ward distribution,infection site and susceptibility test results.Three-dimensional tests were adopted to test AmpC lactamase.RESULTS Among the total 162 strains from respiration department,AmpC producers were 76 strains,accounting for 46.91%. Among the 202 strains from the other departments,however,AmpC producers were 36 strains,accounting for 17.82%.And drug-resistance of E.cloacae from respiration department was distinctly higher than that from the other departments.CONCLUSIONS E.cloacae from respiratory department has the higher isolating rate and drug-resistance rate.We should take effective measurement to contain nosocomial infections with E.cloacae.
