ABSTRACT
OBJECTIVE I understand all types of hospital clinical specimens sent from the main Gram-negative bacillus distribution and resistance,for clinical anti-infection treatment and provide the basis for the rational use of antibiotics.METHODS Clinical submitted the sputum,Blood,Urinary tract secretions,Wound secretions,Humoral etc all kinds of specimens from the conventional training,use Viekt-ATB auto-system,and K-B paper disk diffusion in accordance with NCCLS standards was employed for drug sensitivity tests.RESULTS July 2006 June 2007 Clinical specimens were isolated various major G-Bacillus 707,Habitat of the top three are:Escherichia coli,Klebsiella pneumoniae,Pseudomonas aeruginosa,16 kinds of antibiotics resistance in varying degrees.three major imipenem Enterobacteriaceae bacteria resistant rates are 0.0%,Highly resistant to ampicillin,to cefoperazone/sulbactam,piperacillin/tazobactam resistance rate of 3.3% to 34.0%.In non-fermented bacteria,In addition to Stenotrophomonas maltophilia Aeromonas natural resistance to imipenem,The remaining resistance to imipenem rate of
