Abstract:
Objective To investigate the bacterial distribution and resist-ance to antibiotic of bone and joint infection in China, 2012.Methods The bacteria isolated from bone and joint in the tertiary hospitals were routinely identified.Disc diffusion test, minimum inhibitory concentra-tion ( MIC) test and E-test were used to detect the antimicrobial sensi-tivity.Results All the clinical stains isolated from 557 tertiary hospi-tals.2636 pathogenic strains were collected from bone and joint speci-men, which included Klebsiella pneumonia 370 strains (14.0%), Esche-richia coli 348 strains ( 13.2%) , Acinetobacter baumannii 319 strains (12.1%), Staphylococcus aureus 252 strains (9.6%) and Pseudomonas aeruginosa 167 strains ( 6.3%).The resistant rate of Staphylococcus aureus strains to oxacillin were 36.0%, no vancomycin and linezolid re-sistant isolate were found.The resistant rate of Escherichia coli, Klebsiella pneumonia and Enterobacter cloaecae strains to ceftriaxone were 64.6%, 33.0%and 37.4%, respectively, the resistant rate to imipenem were<2%.The resistant rate of Pseudomonas aeruginosa to carbapenem, ceftazidime and cefepime were <20%, the resistant rate to quinolone were <10%.The resistant of Acinetobacter buamannii to cabarpenem were <40%, the resistant rate to amikacin were 18.8%.The resistant rate of Acinetobacter lwoffii to cabarpenem were <1%, and the resistant rate to pipercillin and cefepime were <10%.Conclusion Gram negative bacteria were predominant organism in bone and joint infections in China, it may be related to the initial em-piric therapy always cover Staphylococcus.There were some difference in bacterial resistance to different antibiotics.These data present information for the proper treatment of bone and joint infections.
