BACKGROUND: The growing prevalence of antimicrobial resistant bacteria has become a serious worldwide problem. There has been an alarming rise in bacteria strains that have resistance to various antimicrobial agents and this has been reported in many parts of the world. The purpose of this study was to analyze antimicrobial resistance information of bacteria species from non-tertiary care hospitals between 2007 and 2014.
METHODS: Susceptibility data were collected from five commercial laboratories. Duplicate isolates were excluded from the analysis. In the analysis of laboratory-generated susceptibility data, the Clinical and Laboratory Standard Institute (CLSI) recommends including only the first isolate if there were multiple isolates from one patient. Intermediate susceptibility was not included in the calculation of resistant rates. The resistance rate was calculated by arithmetic mean method.
RESULTS: The resistance rate of Oxacillin-resistant Staphylococcus aureus ranged from 55 to 63%. The proportion of Vancomycin-resistant Enterococcus faecium was about 12-28%. Ceftazidime-resistant Escherichia coli and Klebsiella pneumoniae were 29% and 47% in 2014. Cefotaxime-resistant E. coli and K. pneumoniae were 31% and 53% in 2014. Meropenem-resistant Pseudomonas aeruginosa was from 22 to 28%. It was noted that the resistance rate for Imipenem-resistant Acinetobacter baumannii considerably increased from 20 to 73%.
CONCLUSION: Antimicrobial resistance surveillance studies are very important for monitoring the levels of endemic or emerging resistance. Although it is impossible to completely solve the problem, it is still necessary to devote more surveillance efforts to help in mitigating the increasing trend of bacterial resistance. The resistance rates of third generation Cephalosporin (cefotaxime, ceftazidime) gradually increased in E. coli and K. pneumoniae between 2007 and 2014. Noticeably, the increase in Imipenem and Meropenem resistance was drastic in A. baumannii.
