Abstract:
OBJECTIVE To investigate the drug-resistant genes in Acinetobacter baumannii(ABA) isolated from Shaoxing and the relationship among them to supply evidences for tracing the source of epidemiology.METHODS Nineteen drug-resistant genes were detected by PCR in 39 strains of ABA.RESULTS TEM-gene was found positive in 13 strains of ABA(33.3%),OXA-23 group-gene was in 20 strains(51.3%),aac(3)-Ⅰ gene was in 23 strains(64.1%),aac(6′)-Ⅰ gene was in 25 strains(64.1%),ant(3″)-Ⅰ gene was in 29 strains(74.4%) and qacE△1-sul1 gene was in 32 strains(81.2%).The others were not found in all 39 isolates detected.Clonial transmitted phenomenon was existed.CONCLUSIONS The carrier rate of TEM,OXA-23group,aac(3)-Ⅰ,aac(6′)-Ⅰ,ant(3″)-Ⅰ and qacE△1-sul1 genes is high in ABA.ABA can induce clonial transmitted hospital infection.
