Study on the Genotyping of Aminoglycoside Modifying Enzymes Genes from Pan-drug Resistant Acinetobacter Baumannii / 医学研究杂志

ABSTRACT

Objective To investigate the genotyping of aminoglycoside modifying enzymes on Pan-drug resistant A..baumannii(PDRA)isolated.Methods The antibiotic susceptibility of 16 different antibiotics of A.baumannii were tested by K-B method,aminoglycoside modifying enzymes coding genes of A.baumannii were detected by PCR.Results The detection rates of OXA-23group were 41.8%and aminoglycoside modifying enzymes coding genes of aac(3)-Ⅰ,aac(6')-Ⅰand ant(3″)-Ⅰ were 64.1%,64.1% and 74.4%.Conclusions The study showed that it is more serious for PDRA carrying aminoglycoside modifying enzymes coding genes.
