Abstract:
Objective To evaluate nasal carriage and antimicrobial resistance of bacteria in health care workers (HCWs)in an intensive care unit (ICU),and provide basis for making prevention and control measures of health-care-associated infection(HAI).Methods From April 2014 to March 2015,nasal swabs from HCWs in ICU were collected,carriage and antimicrobial resistance of bacteria were detected.Results A total of 450 nasal swab speci-mens were taken,137 strains were isolated,isolation rate was 30.44%.There were no significant difference in na-sal carriage rates of bacteria in HCWs with different genders,ages,types of work,length of service,and education-al level (P >0.05);nasal carriage rates in HCWs at different seasons were significantly different (P <0.05 ).82 strains (59.85%)were gram-negative bacteria,the major were Klebsiella pneumoniae (21 .16%)and Enterobacter aerogenes (18.98%);55 strains (40.15% )were gram-positive bacteria,the major were Staphylococcus aureus (18.98%)and Staphylococcus epidermidis (15.33%).38 (27.74% )strains were multidrug-resistant strains. 7.69% (2/26)of Staphylococcus aureus were methicillin-resistant strains,3.45%(1/29)of Klebsiella pneumoniae and 3.85%(1/26)of Enterobacter aerogenes were imipenem-resistant strains.Conclusion Nasal carriage rate of bac-teria and detection rate of multidrug-resistant organisms in HCWs in ICU is high.
