ANALYSIS ON BACTERIAL DISTRIBUTION AND DRUG RESISTANCE IN LOWER RESPIRATORY TRACT INFECTION DISEASE AMONG SENILE PATIENTS

[Objective] To investigate the bacterial distribution and drug resistance in lower respiratory tract disease among senile patients and to provide data for clinical treatment.[Methods] The sputum and secretion of lower respiratory tract were collected from 629 senile patients who were diagnosed with lower respiratory tract infection patients from 2004 to 2005.A11 the specimen were given identification and antibiotic resistance with Microscan Auto SCANT4.[Results] Among the strains of pathogens,Gram-negative bacilli was 72.7%,Gram-positive 16.4%,and eumycete 11%.The most common five kinds were Klebsiella pneumonia,Pseudomonas aeruginosa,Escherichia coli,S.aureus and eumycete.The drug sensitivity results showed that all the strains were highly resistant to commonly used antibiotics.No vancomycin-resistant strains were found in Gram-positive bacilli.Imipenem,cefazolin and cefoperazone /sulbactam had high sensitivity to Gram-negative bacilli.[Conclusion] The most common strains of the specimen from aged patients of lower respiratory tract infection disease are Gram-negative bacilli and have highly resistance to common and antibiotics.Identification and antibiotic resistance of the secretion of lower tract must be strengthened,and give the effective data for clinician.
