Abstract:
OBJECTIVE To study the distribution of the nonfermenter(NF) and the change in its resistance between 2002 and 2005 in our hospital ICU,and instruct clinical application of antibiotics reasonably.METHODS The(identification) of bacteria, antibiotic susceptibility and the detection by VITEK-32 of GNI~+、GNS-142 were used.Etest was applied for detection of metallo-?-lactamase.RESULTS The detective rate of the NF was 57.3%,(58.3%),67.5% and 69.8%,(respectively) from 2002 to 2005.Pseudomonas aeruginosa(PAE),Acinetobacter baumannii and (Stenotrophomonas) maltophilia accounted for 34.3%,11.1% and 4.0%,respectively.The highest distribution of the NF was in the sputum.The resistance rate of PAE to imipenem was lower,(however),it had rose from 0.0% to 17.8% in 2005.The resistance rate of S.maltophilia to sulfamethoxazole/(trimethoprim) was lower than the others,and rose from 0.0% in 2002 to 13.8% in 2005.The incidence rates of(metallo)-?-lactamase of PAE was 0.8% and of A.baumannii was 4.8%,respectively;the incidence rates of metallo-?-lactamase of A.baumannii and PAE were 0.8% and 4.8%,respectively.CONCLUSIONS The(detective) rates of PAE, and A.(baumannii) are gradually increased during the last four years.The incidence of(metallo)-?-lactamase of PAE and A.baumannii is also lower,and the other resistance is existed.
