Lower Respiratory Tract Infection in Respiration Department Caused by Pseudomo nas Aeruginosa:Resistance Analysis

Objective To investigate the resistance of pseudomonas aeruginosa to antibiotics in lower respiratory tract infection in respiration department caused by pseudomonas aeruginosa to guide the reasonable use of antibiotics clinically.Methods The sputum samples from the inpatients with lower respiratory tract infection in the respiratory department between Jan.2009 to Dec.2009 were collected,isolated and cultured,and the identification and susceptibility testing were carried out by using an automatic microbiological analyzer.Results The resistance rate of pseudomonas aeruginosa to ceftriaxone(97.2%) was the highest,followed by cotrimoxazole(72.2%),cefotaxime(62.5%),ceftizoxime(62.5%),tetracycline(62.5%)and aztreonam(51.4%),the resistance rate of 6 antimicrobial drugs reaching 50%.Conclusion Lower respiratory tract infections caused by pseudomonas aeruginosa show multiple drug resistance,and therefore,reasonable care should be needed in clinical use of antibiotics.
