ABSTRACT
Objective To investigate the distribution and antimicrobial resistance of pathogens causing pneumonia in acute stroke patients,and guide clinical antimicrobial use.Methods Patients with stroke-associated pneumonia (SAP)admitted to a tertiary first-class hospital from 2008 to 2013 were investigated retrospectively,distribution and antimicrobial susceptibility testing results of pathogens from sputum were analyzed.Results A total of 98 pa-tients with SAP were investigated,124 stains were isolated from sputum specimens,75 strains (60.48% )were gram-negative bacteria,44 (35.49% )were gram-positive bacteria,and 5 (4.03% )were fungi. There were 21 cases of mixed infection (21.43% ),bacterial alterations during treatment process existed among 23 cases(23.47% ).The top 4 isolated pathogens were Staphylococcus aureus (S. aureus,n= 43,34.68% ),Klebsiella pneumoniae (K. pneumoniae,n= 19,15.32% ),Pseudomonasaeruginosa(P. aeruginosa,n= 18,14.52% ),and Acinetobacterbau-mannii(A. baumannii,n= 18,14.52% ). Antimicrobial resistance rates of K. pneumoniae were all 80% ,resistance rates of P.aeruginosa to imipenem was 33 .33% . No resistant strains were detected among fungi.Conclusion The main pathogens causing SAP in this hospital are S.au-reus,K.pneumoniae,A.baumannii,and P.aeruginosa,except K.pneumoniae,the other strains are severely re-sistant to antimicrobial agents,clinicians should choose antimicrobial agents according to the distribution character-istics and antimicrobial susceptibility testing results.
