Abstract:
Objective:Through statistical analysis of drug resistance and homology of Acinetobacter baumannii in geriatric department of our hospital, we can provide evidence for clinical experience in antibiotics use and nosocomial infection control.
Methods:The drug resistance of Acinetobacter baumannii isolated from the elderly rehabilitation department in Ningbo Kangning Hospital from January 2017 to December 2018 was analyzed by retrospective analysis.The homology of Acinetobacter baumannii isolated from clinical isolates was detected by PCR ERIC-PCR method and agarose gel electrophoresis method.
Results:The resistance rates of Acinetobacter baumannii to ciprofloxacin and levofloxacin were 41.6% and 35.4%, respectively.The resistance rates to cefepime, ceftriaxone and ceftazidime were 40.3%, 38.9% and 36.7%, respectively.The resistance rate to imipenem was 38.9%, and the sensitivity rates to cefoperazone/sulbactam, gentamicin and tobramycin were all over 70%.A total of 226 strains of Acinetobacter baumannii were genotyped by ERIC-PCR.They were mainly classified into A, B, C, D and E 5 types.Among them, 116 strains were type A, 68 strains were type B, 26 strains were type C, 8 strains were type D and E.
Conclusion:The resistance rate of Acinetobacter baumannii to some antibiotics in geriatric rehabilitation department is still at a high level, so we should continue to strengthen the rational use of antibiotics; at the same time, the strains are highly homologous, and there is likely to be clonal transmission in the department, so we should take more effective measures to prevent and control its transmission in hospital.
