Clinical distribution of Pseudomonas aeruginosa and its drug resistance status in the past 5 years

Objective To study the distribution of Pseudomonas aeruginosa and its drug resistance in our hospital from 2006 to 2010 in order to provided the scientific evidence for rational use of antibiotics. Methods Bacteria were identified with the VITEK system and antibiotic sensitivity was tested by BIOMIC.Drug resistance of Pseudomonas aeruginosa was analyzed using the WHONET 5.4 software. Results The most dominant organism was Pseudomonas aeruginosa with a detection rate of 72.9% in sputum and 7.6% in urine from 2006 to 2010.The sensitivity of Pseudomonas aeruginosa to FEP was the lowest（11.4%-34.3%）,followed by CAZ（13.9%-37.7%）,ATM（17.5%-66.7%）,and AMK（13.3%-46.6%）. Conclusion The drug resistance of Pseudomonas aeruginosa isolated from sputum is higher than that isolated from urine with an increase tendency to IPM.
