ABSTRACT Acinetobacter baumannii has emerged as an important pathogen lead-
ing to multiple nosocomial outbreaks. Here, we describe the genomic sequence of a
multidrug-resistant Acinetobacter baumannii sequence type 164 (ST164) isolate from
a hospital patient in Sudan. To our knowledge, this is the first reported draft ge-
nome of an A. baumannii strain isolated from Sudan.
A
cinetobacter baumannii is an aerobic Gram-negative bacillus frequently linked to
health care-associated infections. A. baumannii causes a wide spectrum of infec-
tions that includes pneumonia, bacteremia, meningitis, and urinary tract infection (1, 2).
Its ability to persist for extended periods, in combination with increasing antibiotic
resistance, makes it a frequent cause of nosocomial outbreaks. Here, we report the draft
genome sequence of an A. baumannii strain (NUBRI-A) isolated from a patient admitted
to a private hospital in Khartoum, Sudan.
A sputum sample was collected from a 35-year-old male admitted to the Royal Care
International Hospital in Khartoum, Sudan, with a pneumonia infection. The specimen
was directly inoculated on MacConkey agar and then incubated overnight under
aerobic conditions at 37°C. The colony was identified using Gram staining and bio-
chemical tests that included oxidase, catalase, Kligler’s iron agar, sulfide indole motility,
citrate agar, and urea tests. The analytical profile index was used to confirm the species
(3). Genomic DNA was extracted using the QIAamp DNA minikit (Qiagen, Germany), and
paired-end libraries were prepared using the Nextera DNA Flex library kit, followed by
2 300-bp sequencing on a MiSeq platform (Illumina, Inc., USA). The sequenced reads
were trimmed using Sickle version 1.33 (with the parameters -q 20 -l 75) (https://github
.com/najoshi/sickle) and de novo assembled using SPAdes version 3.11 (with the
parameters -careful and -cov-cutoff auto) (4). All resultant contiguous sequences were
then submitted to the NCBI Prokaryotic Genome Annotation Pipeline (5). Multilocus
sequence typing (MLST) was determined using mlst (https://github.com/tseemann/
mlst). This study was approved by the Research Ethics Committee at the National
University in Sudan.
A total of 1,777,192 paired-end reads were obtained from the whole-genome
sequencing of NUBRI-A. Quality-controlled reads (1,768,578 reads; average length,
211 bp) with a Phred score of 20 were assembled. The assembled genome was
composed of 33 contigs (all were longer than 200 bp), and the longest contig size was
1,777,326 bp, covering 3,743,802 bp. The GC content and N
50
value were 38.9% and
390,599 bp, respectively. The genome assembly metric was calculated with QUAST
version 5.0.2 using default parameters. The total number of genes is 3,576; of those,
3,444 are protein-coding genes, 70 are RNA genes, and 62 are pseudogenes. MLST
(Oxford scheme) on this strain revealed that it belongs to sequence type 164 (ST164).
