Draft genome sequence and intact prophage characterisation of multidrug-resistant Acinetobacter baumannii isolate ABU3 from a tracheal suction specimen in Thailand

Multidrug-resistant <i>Acinetobacter baumannii</i> ABU3 was isolated from a tracheal suction specimen from a 76-year-old female patient in Thailand. The draft genome was sequenced using Illumina NextSeq 550. The genome comprised 95 contigs totaling 3826,273 base pairs with an N50 of 112,717 bp and GC content of 38.89. Digital DNA-DNA hybridisation with <i>A. baumannii</i> ATCC 19606^T revealed 80.3 % similarity. MLST assigned the isolate to ST-164, whereas MLST of the core genome showed 99.0 % similarity to cgST-4302. Resistance gene analysis identified <i>bla</i> _OXA-23, <i>bla</i> _CARB variants, <i>bla</i> _ADC-25, and <i>tet</i>(39). Antimicrobial susceptibility testing showed resistance to carbapenems, fluoroquinolones, beta-lactam combinations, extended-spectrum cephalosporins, and penicillins, with sensitivity to aminoglycosides and folate pathway inhibitors. Two intact prophage regions (23.5 and 26.3 kb) were identified containing structural and functional components. Data are available at NCBI under BioProject PRJNA550309.
