An IMP-4-producing Acinetobacter pittii strain coproducing oxacillinases was isolated from a leg wound of a 67-year-old female patient. Identification to the species level by rpoB and gyrB sequencing and multiplex-PCR-based analysis revealed that the isolate was A. pittii. Whole-genome sequencing of this A. pittii isolate determined the presence of blaOXA-96, blaCARB-2, and a novel blaOXA-421 gene. The position of this novel blaOXA-421 gene was similar to that of blaOXA-51 in A. baumannii, downstream of the phosphinothricin N-acetyltransferase gene and upstream of fxsA in the chromosome. This A. pittii isolate was found to belong to sequence type 119 (ST119). Here, we report the first isolation of IMP-4-producing A. pittii ST119 with a novel blaOXA-421 gene from a patient in Australia and characterize its draft genome.
从一名67岁女性患者的腿部伤口分离出一株产IMP-4的皮氏不动杆菌,该菌株同时产奥沙西林酶。通过rpoB和gyrB测序以及基于多重PCR的分析在种水平上鉴定表明,该分离株为皮氏不动杆菌。对该皮氏不动杆菌分离株进行全基因组测序确定存在blaOXA-96、blaCARB-2和一个新的blaOXA-421基因。这个新的blaOXA-421基因的位置与鲍曼不动杆菌中blaOXA-51的位置相似,位于染色体上膦丝菌素N-乙酰转移酶基因下游和fxsA上游。发现该皮氏不动杆菌分离株属于序列型119(ST119)。在此,我们报道了在澳大利亚首次从一名患者中分离出产IMP-4的携带新blaOXA-421基因的皮氏不动杆菌ST119,并对其草图基因组进行了表征。
