Abstract:
Objective To investigate the distribution and antimicrobial resistance of pathogens isolated from surgi-cal patients with infection.Methods Distribution and antimicrobial resistance of 1 208 pathogens isolated from sur-gical patients with infection from January 2013 to January 2014 were analyzed retrospectively.Results Of 1 208 pathogenic isolates,gram-negative bacteria,gram-positive bacteria and fungi accounted for 64.57% (n = 780 ), 24.92%(n = 301 )and 10.51 % (n = 127 )respectively.The main specimens were sputum (44.78%),urine (21 .11 %),blood(11 .51 %),and pus(10.26%).Antimicrobial susceptibility testing results showed that the produ-cing rate of extended-spectrumβ-lactamases (ESBLs)of Escherichia coli and Klebsiella pneumoniae was 62.60%and 33.61 % respectively,resistant rate to imipenem was 0.76% and 15.57%,respectively.The resistant rate of Pseudomonas aeruginosa and Acinetobacter baumannii to imipenem was 38.93% and 75.80% respectively.Methi-cillin-resistant Staphylococcus aureus and methicillin-resistant coagulase negative Staphylococcus was 71 .68% and 87.93% respectively.Conclusion The major pathogens isolated from surgical patients with infection are gram-neg-ative bacteria,the main infection sites are respiratory tract and urinary tract in this hospital;multidrug resistance is serious,especially carbapenem resistance,which should be paid attention.
