RESUMEN

OBJECTIVE To study the distribution and antimicrobial resistance of Acinetobacter baumannii infection in our hospital.METHODS Five hundred and sixty-nine strains of A.baumannii isolated from patients with infection from Jan 2001 to Dec 2005 were collected and antimicrobial susceptibility tests were performed.RESULTS Two hundred and seventy-five strains(48.3%) of A.baumannii were from intensive care unit(ICU).Four hundred and five strains(71.2%) of A.baumannii were examined from sputum.A.baumannii had various drug resistances to 12 antibiotics,which were monitored and proved tending to strengthen.The resistance rate in the ICU was distinctly higher than the others with significant difference(P

RESUMEN

OBJECTIVE To investigate the vicissitudes of resistance to imipenem in Gram-negative bacilli isolated from clinical specimens.METHODS Gram-negative bacilli were isolated from various clinical specimens in our hosptial from Jan 2004 to Jan 2008.The identification and antimicrobiol susceptiblity test was determined by VITEK-AMS full automated microbiology analyzer.RESULTS A total of 6983 strains of Gram-negative bacilli were isolated,including 92 species and 2986 isolates of Enterobacteriaceae and 3961 isolates of non-fermenters,accounted for 42.8% and 56.7%,respectively.The resistant rate of Enterobacteriaceae to imipenem was lower than 1.0%.The resistant rates of Stenotrophomonas maltophilia,Burkholderia cepacia,Chryseobacterium meningosepticum,Pseudomonas aeruginosaand Acinetobacter baumannii to imipenem were 98.4%,97.0%,98.2%,70.1% and 47.5%,respectively.CONCLUSIONS Non-fermenters are predominant pathogens.Imipenem has high antimicrobial activity to Enterobacteriaceae in invro,but not to non-fermenters.The resistant rates of P.aeruginosa and A.baumannii to imipenem are increasing gradually.
