Clinical Distribution and Antibiotic Resistance of 1909 Stains of Pseudomonas Aeruginosa / 医学研究杂志

ABSTRACT

Objective To discuss the clinical distribution and antibiotic resistance of 1909 strains of Pseudomonas aeruginosa(PA)to 19 antibiotics.Methods To collect and isolate clinical specimens from Jan to Dec in 2007,and analysis the drug resistance of 1909 stains of PA.Results The top three departments of infection rnte are Senior Officials inpatient Ward(38.9%),Neurology Department(28.1%)and Pneumology Department(19.58%).The drug with the highest level of antibiotic resistance is Trimethoprin/Sulfa(96.3%),the second one is Tetracycline(95.3%),and drugs with low level antibiotic resistance are imipenem(39.8%),Ceftazidime(29%),Piperacillin/Tazobactam(28%),amikacin(14%),respectively.Conclusion PA is a main pathogenic bacteria for bedridden patients and critically ill patients in ICU.It's important to choose antibiotics reasonably,and it's necessary to acontrol the path of hospital-acquired infection.
