Experimental Identification of Mucoid Pseudomonas Aeruginosa Strains Causing Infections and Cases Review / 现代检验医学杂志

ABSTRACT

Objective To investigate the clinical distribution and antibacterial drug susceptibility of mucoid Pseudomonas aeruginosa (mPa).Methods By looking at the patients’general information,disease information and the information of anti-microbial usage,cases of 53 strains of non-repetitive mucoid Pseudomonas aeruginosa were collected from hospitalized pa-tients from Jan 2013 to Dec 2013,and drug susceptibility were analyzed.Results A total of 53 strains of mucoid Pseudo-monas aeruginosa were isolated from sputum specimen,mainly elderly patients with a mean age of 66.7±9.1 years old;50 patients had chronic history of respiratory infections,all patients were used during the hospital stay of two or more kinds of antibiotics,used jointly only 11 cases of macrolides.All strains to commonly used antimicrobial agents showed a higher sen-sitivity in vitro,in addition to ticarcillin/clavulanate (64.2%),cefepime (60.4%),other drug sensitivity was higher than 70%.Conclusion Mucoid Pseudomonas aeruginosa was susceptible to chronic respiratory infection history of the elderly,its antimicrobial susceptibility was high in vitro,the use of antimicrobial agents in clinical was combined therapy compared,but utilization rate of macrolides drugs was low.
