ABSTRACT
Objective To investigate the bacterial distribution and antibiotic resistance profile in Tongling People's Hospital during 2016.Methods All the clinically isolated bacterial strains in Tongling People's Hospital during 2016 were identified and tested for their susceptibility to antimicrobial agents.The results were analyzed with WHONET 5.6 software.Results A total of 2 949 strains of bacteria were collected,including 2 134 strains of gram-negative bacteria and 815 strains of gram-positive bacteria.The top five gram-negative bacteria were E.coli,4.baumannii,K.pneumoniae,P.aeruginosa and Enterobacter.The top five gram positive bacteria were coagulase-negative Staphylococcus,S.aureus,E.faecalis,E.faecium and Streptococcus.The prevalence of ESBLs-producing strains was 42.3％ in E.coli and 31.1％ in K.pneumoniae,The prevalence of carbapenem-resistant strains was 1.2％ (8/640) in E.coli isolates and 29.4％ (108/367) in K.pneumoniae isolates.Majority (94.3％) ofA.baumannii strains were susceptible to tigecycline.However,74.3％ and 74.9％ of these strains were resistant to imipenem and meropenem,respectively.Most P aeruginosa strains (78.2％) were resistant to piperacillin,but about 70％ were susceptible to carbapenem antibiotics.The prevalence of methicillin-resistant strains was 32.0％ (74/231) in S.aureus and 65.6％ (170/259) in coagulase-negative Staphylococcus.No staphylococcal strains were found resistant to teicoplanin or vancomycin.No enterococcal isolates were resistant to teicoplanin or linezolid.Conclusions The number of bacterial isolates in this hospital is increasing year by year.The prevalence of multidrug-resistant bacteria is also on rise,especially the pandrug-resistant Enterobacteriaceae and A.baumannii.It is urgently required to strengthen the control of hospital infections.
