Abstract:
Objective To investigate the bacterial distribution and resistance in orthopedic patients with wound infections in the hospital in 2014 .Methods The bacteria identification and the antimicrobial susceptibility test were conducted by VITEK‐2 compact automatic system .Results A total of 864 pathogenic strains were collected ,with Gram‐positive bacteria 451 strains (52 .2% ) , Gram‐negative bacteria 398 strains(46 .1% ) .The first major pathogens of Gram‐positive bacteria were Staphylococcus aureus(n=233 ,27% );The top three pathogens of Gram‐negative bacteria were Pseudomonas aeruginosa(n=94 ,10 .9% ) ,Enterobacter cloacae (n=63 ,7 .3% ) ,Acinetobacter baumannii(n=58 ,6 .7% ) .All the Staphylococcus aureus isolates were susceptible to vancomycin , tigecycline ,nitrofuratoin ,quinupristin/dalfopristin ,linezolid .The resistant rates of Acinetobacter baumannii were higher than 50%to multiple antibiotics .Conclusion Staphylococcus aureus were predominant pathogens in orthopedic patients with wound infec‐tions in our hospital .Meantime ,Pseudomonas aeruginosa and Enterobacter cloacae were the prime pathogens in the Gram‐negative bacteria .The drug‐resistance situation is still severe ,and more effective measures should be taken to control the dissemination and growth of resistant strains .
