Analysis of Bacterial Distribution and Drug Resistance in Lower Respiratory Tract Infection for Patients in Respiratory Department

Objective：To analyze the bacterial distribution and drug resistance in lower respiratory tract infection for patients in respiratory department.Method：We reviewed 224 patients suffered from lower respiratory tract infection,and made the pathogenic bacterium cultivation for secretion of the patients and then took the susceptibility test.Result：Totally 251 pathogenic bacteria were found in secretion of the patients.The major pathogenic bacteria were pseudomonas aeruginosa,baumanii and staphylococcus aureus.Drug resistances were common in Gram-negative bacilli（GNB） and Gram-positive cocci.Piperacillin/tazobactam and cefoperazone/sulbactam and imipenem were the most sensitive for GNB.S.aureus,Streptococcus pneumoniae and S.epidermi were all sensitive to vancomycin.Fungus account to 20.3%.Conclusion：Drug resistance of the pathogenicbacteria in lower respiratory tract infection is common,and it′s of great importance to emphasize pathogenic bacterium monitoring and use the antibacterials exactly.
