Analysis on pathogenic bacterium distribution and drug resistance of the patients with lower respiratory tract infection / 中国基层医药

ABSTRACT

ObjectiveTo analyze pathogenic bacterium distribution and drug resistance to the inpatients suffered from lower respira.tory tract infection in our hospital,and to guide adminisrration in clinical. MethodsThe inpatients' sputum specimens were collected,and automatic microorganism identification and drug resistance test were conducted,and the records were taken down and statisticly analyzed. Results Among 321 sputum examples,194strains pathogenic bacterium were isolated.And pathogenic bacterium distributed were as following there were 126 strains gram-negative bacilli,accounting for 64.95%,there were 32 strains of gram-postive cocci,accounting for 15.98%,and there were 37 strains of fungi,accounting for 19.08%.The drug resistance of gram-negative bacilli to ampicillin,trimethoprim-sulfamethoxazol were relatively high,accounting for 87.45%～97.74% and 75.37%～91.75%,respectively.Pseudomonas aeruginosa and baumanii were resistant to selected antibiotics at high degree,and showed multiple drug resistance. ConclusionThe species of pathogenic bacterium were various.Gram-negative bacteria were the rnain pathogenic bacteria involved in respiratory tract infection.The drug resistance was high in Pseudomonas aeruginosa and baumanii.
