Analysis of antibacterial activity of nitrofurantoin from gram negative bacilli / 中国基层医药

ABSTRACT

Objective To understand the antibacterial activity of nitrofurantoin from gram negative bacilli,provide the basis for clinical rational use of furan appropriate for drugs.Methods Gram negative bacilli 5 589 strains isolated from clinical were monitored between January 2009 and December 2009.VITEK 2 Compact automatic bacteria identification instrument was used for bacteria identification and drug sensitive test.Whonet 5.6 software was used for data analysis.Results E.coli and klebsiella bacteria produced acid with nitrofurantoin had good antibacterial activity (resistance to ＜ 4.3%),E.coli and klebsiella pneumoniae to with nitrofurantoin for antimicrobial activity was good (the percentages of 25.6% ～ 25.6%),pseudomonas aeruginosa,acinetobacter baumannii,singular deformation bacteria and glue abdulrahman al saleh,bacterium antibacterial activity of furan appropriate for poorer(ni 93.7% ～ 98.9%).Imine resistance from south pseudomonas aeruginosa (IRPA),resistant to carbon penicillium alkene antimicrobial acinetobacter baumannii(CR-AB) and penicillium carbon alkene antimicrobial drug resistant enterobacteriaceae bacteria(CRE) with nitrofurantoin because of the percentages were 100.0% (108/108),100.0% (335/335) and 96.1% (74/77).Conclusion Urine,blood,pus,and secretion of primary separation of E.coli with nitrofurantoin has better antimicrobial activity; Sputum specimens of primary separation of pseudomonas aeruginosa and acinetobacter baumannii with nitrofurantoin has the high prevalence of resistance.
