Abstract:
OBJECTIVE To investigate the changes in pathogenic bacteria and drug resistance in nosocomial(septicemia).METHODS The blood samples of inpatients were cultured with blood culture apparatus,VITEK-AMS were used to identify the pathogenic bacteria and conduct drug resistance test.RESULTS The proportion of(Gram-positive) cocci had been increasing,coagulase negative staphylococcus increased significantly,but the(proportion) of Staphylococcus aureus decreased significantly.The proportion of Gram-negative bacteria and fungi decreased too.Vancomycin and imipenem were the highest susceptible to Gram-positive and Gram-negative(bacteria),respectively.CONCLUSIONS Gram-negative bacteria are the major pathogens in nosocomial septicemia.But Gram-positive cocci had been increasing in the past years.Coagulase negative staphylococcus is the main pathogen in nosocomial septicemia.pathogenic bacteria are higher resistant to the commonly used antibiotics.
