Abstract:
OBJECTIVE To investigate the phylogenetic analysis of Acinetobacter baumannii strains in elderly.METHODS The 33 kinds resistant genes were detected by PCR and cluster analysis.RESULTS The positive rates of AmpC(chromosome type),TEM and PER were 85%,55% and 25%,respectively.The positive rates of aac(3)-Ⅰ,ant(3″)-Ⅰ,aac(3)-Ⅱ,aac(6′)-Ⅰb and armA were 95%,95%,40%,15% and 35%,respectively.The positive rate of qacE△1-sul1 was 75%.There were very high positive percentages of AmpC(chromosome type),TEM,PER,aac(3)-Ⅰ,ant(3″)-Ⅰ,armA and qacE△1-sul1 genes in A.baumannii isolates among elderly.There were clones transmitted phenomenon.CONCLUSIONS The resistance phenotype of A.baumannii isolates among elderly is in accordance with genetic testing.A.baumannii can induce clones transmitted hospital infection.
