Pathogens and antibiotic resistance analysis in urinary tract infection

Objective To investigate the bacterial distribution trend of drug resistance in uninary tract infection(UTI).Methods The antibiotic resistance of clinical isolates from urinary trcat infection from July,2004 to December,2007 was analyzed.Results Among 467 isolates,348 strains(74.52%)were Gram-negative bacilli,69(14.78%)were Gram-positive cocci and 50(10.71%)fungi.The majority of Gram-negative bacilli were Escherichia coli(50.01%)and the majority of fungi was Candida albicans,as for Gram-positive cocci,were Enterococcus faecalis and coagulase negative Staphylococcus.Drug resistance rate of common antibiotic against the majority of urinary pathogens showed an ascending trend.Conclusion Ecoli is still the primary urinary pathogen,but the antibiotic resistance of commonly encountered pathogens is on the rise.
