RESUMO
Objective To investigate the distribution status of Pseudomonas aeruginosa (PA) in children in Suining area and the changes of drug-resistance spectrum to provide the basis for clinical antibacterial drugs selection .Methods The ATB microbiologi-cal system was adopted to identify the bacteria and the K-B method was used to conduct the drug sensitivity test .The detection situ-ation of PA in our hospital from January 2010 to December 2012 was performed the statistical analysis on the distribution in various specialties of pediatrics and drug resistance .Results Among 46 isolated strains of PA ,39 strains were mainly distributed in the specialties of respiration ,neonatology and pediatric intensive care unit (PICU) ,which accounted for 84 .8 % ,22 strains were isolated from sputum specimens ,which accounted for 47 .83% .The isolation rate in last three years showed the rising trend year by year , and the resistance to antibiotics was increased year after year .Conclusion PA is one of the main pathogens of clinical infection .We should strengthen its drug-resistance monitoring and use antibacterial drugs reasonably .
