【摘要】Objective To understand the distribution and antimicrobial resistance of pathogens isolated from bone and joint infection sites of orthopedic patients,so as to provide reference for prevention and therapy of bone and joint infection.Methods 114 specimens from bone and joint infection sites of orthopedic patients between June 2010 and October 2013 were surveyed,pathogens and antimicrobial susceptibility of pathogens were analyzed.Results A total of 145 pathogenic isolates were
obtained,62.07%(n=90)of
which
were
gram-negative
bacteria,34.48%(n=50)were gram-positive bacteria,2.07%(n=3)were
Candida spp .,and 1 .38%(n =2)were anaerobic bacteria. The top 4 pathogens were Pseudomonas aeruginosa (20.69%),Staphylococcus aureus (12.41 %),Escherichia coli (11 .03 %),and Enterobacter cloacae (9.65%).These pathogens presented remarkable resistance.The resistant rate of Pseudomonas aeruginosa to ceftazidime was up to 40.00%;the resistant
