Abstract:
OBJECTIVE To analyze the pathogens distribution and the antibiotic resistant characters.METHODS Sputum culture was performed in 267 cases who suffered from lower respiratory tract infection in emergency ward from Jan 2004 to Jun 2007.The results of 183 pathogens and drug sensitivity were analyzed.RESULTS The detected 183 strains of pathogens showed that Gram-negative bacilli accounted for 77.1%(Klebsiella pneumoniae was in the first place) and Gram-positive cocci were for 22.9%(Enterococcus faecium and Staphylococcus aureus were in the first places),the total drug resistance rate of Gram-negative bacilli to gentamicin,cefazolin,SMZ/TMP,piperacillin,ciprofloxacin and aztreonam had highly reached 60.5-70%,however to meropenem,cefepime,amikacin,imipenem and Sulperazone was 32.5-38.6%.Gram-positive cocci appeared generally higher multidrug resistant,the drug resistance rate of Gram-positive cocci to penicillins and erythromycin was all 100%,but the resistantce of Gram-positive cocci to vancomycin hadn′t been found.CONCLUSIONS Gram-negative bacilli are major pathogens in lower respiratory tract infection of emergency ward,K.pneumoniae is in the first place of Gram-negative bacilli and E.faecium and S.aureus are in the first places of Gram-positve cocci,both of them appearing highly multidrug resistant,analysis of pathogens and drug sensitivity are necessary to rational antibiotics usage,and the immunological protection should be enhanced.
