AbaR5, a large multiple-antibiotic resistance region found in Acinetobacter baumannii

Abstract

A multiply antibiotic-resistant Acinetobacter baumannii strain, 3208, contains the aacC1-orfP-orfP-orfQ-aadA1 gene cassette array; sul1, tetA(A), and aphA1b genes; and a mer operon in a large region containing a novel transposon, Tn6020, and segments of Tn1696, Tn21, Tn1721, and Tn5393. This region is part of a genomic resistance island, AbaR5, related to and found in the same chromosomal position as AbaR1. This strain is the first European clone I isolate detected in Australia.
