RESUMO
Objective To explore the bacterial spectrum and drug resistance that separated from respiratory tract of schizophrene.Methods 311 samples taken from the respiratory tract of schizophrenes were investigated and analyzed.Results From 311 samples 58 pathogenic bacteria were separated,the gram negative was 55.93% and the gram positives was 44.07%;5 most pathogenic commoly bacteria were klesbsiella pneumoniae and S.aureus and escherichia coli and streptococcus and enterococcus;Except that all the staphylococcus were sensitive to vancomycin,enterobacteriaceae were sensitive to imipenem,all the other separated strains showed total resistance to the agents tested in different levels,also the multidrug resistance emerged in lower respiratory tract infections with mulitidrug resistance in high levels.Conclusion The most common pathogenic bacteria separated from these schizophrene are klesbaiella pneumoniae and S.aureus.In clinical therapy,sensitive antibiotics should be selected according to the drug sensitive tests,combine with other agents when necessary to accelerate the clearance of bacteria from infectious respiratory tract in schizophrene.
