Complete genome sequence of an extensively drug resistant (XDR) M. morganii SMM01 isolated from a patient with urinary and fecal incontinence



M. morganii is a gram-negative, non-lactose fermenting and an opportunistic pathogen frequently associated with nosocomial infections. Although first isolated in 1906 from a pediatric fecal sample, not many M. morganii isolates have been sequenced. The objective of this work is to determine the complete genome sequence of an XDR M. morganii strain (SMM01) isolated from the urine of a patient with urinary and fecal incontinence and to characterize its antimicrobial resistance profile.

Data description

Here, we report the complete genome sequence of M. morganii SMM01 generated from the hybrid assembly of Illumina HiSeq X and Nanopore MinION reads. The assembly is 100% complete with genome size of 39,30,130 bp and GC content of 51%. Genomic features include 3617 CDS, 18 rRNAs, 78 tRNAs, 4 ncRNAs and 60 pseudogenes. Antimicrobial resistance profile was characterized by the presence of genes conferring resistance to aminoglycosides, β-lactams, fluoroquinolones, chloramphenicol, and tetracyclines. Secondary metabolite biosynthetic gene clusters like NRPS, T1PKS, thiopeptide, beta-lactone, and bacteriocin were identified. The genome data described here would be the first complete genome of an Indian M. morganii isolate providing crucial information on antimicrobial resistance patterns, paving the way for further comparative genome analyses.


M. morganii is a gram-negative, facultative, non-lactose fermenting bacterium belonging to the tribe Proteae of Enterobacteriaceae family. This opportunistic pathogen was first reported in 1906 from a pediatric fecal sample [1]. M. morganii is often encountered among postoperative, immunocompromised, and intensive care unit patients [2, 3] causing catheter-associated urinary tract infections (CAUTI), sepsis and wound infections [4]. As on 24th January 2021, 98 M. morganii genomes were available in the NCBI Genbank, of which 20 were complete genomes. The objective of this study is to characterize a new, clinically isolated XDR M. morganii strain by whole genome sequencing to understand its antimicrobial resistance profile.

Here, we report a complete genome sequence of M. morganii, isolated from the urine sample of a male patient in 2018 at Sri Sathya Sai Institute of Higher Medical Sciences (SSSIHMS) Prasanthigram, India (14.1670 N 77.8091 E). The patient was admitted to the urology ward due to urinary and fecal incontinence and had a history of Road Traffic Accident (RTA), 1 year prior to the isolation of the strain. The isolate was identified as M. morganii by MALDI-TOF MS. Antibiotic Susceptibility Testing (AST) and Minimum Inhibitory Concentrations (MICs) were determined using Vitek2 as per CLSI guidelines [5].

Whole genome sequencing of M. morganii SMM01 was performed using Illumina HiSeq X (short reads technology) and Nanopore MinION (long reads technology) platforms. The reads from both the sequencing platforms were used to generate hybrid assembly using Unicycler. To the best of our knowledge, this would be the first complete genome sequence of M. morganii from India.

Data description

Upon isolation and strain purification, the isolate SMM01 was cultivated in LB broth. AST was performed using N281 card in Vitek2 and the study isolate SMM01 was found to be resistant to all the tested antibiotics except aminoglycosides (Amikacin and Gentamicin). Total genomic DNA was extracted using Macherey Nagel Nucleospin® DNA extraction kit as per manufacturer’s instructions.

Oxford Nanopore Technologies (ONT) Minion sequencing libraries were prepared using the ligation sequencing kit (SQK-LSK109) and data was collected from the FLO-MIN106 flow cell. Base-calling and demultiplexing was done using Albacore v2.0.1. MinION sequencing run produced 30,881 reads with the mean read quality score of 7.7 as assessed with NanoStat [6] (Data file 1) [7]. The passed reads were taken for adapter removal using Porechop v0.2.4 ( Illumina sequencing libraries were prepared using the NEBNext Ultra II DNA library preparation kit (E7645S). The libraries were pooled after performing quantity and quality checks using Qubit2 and Agilent Bioanalyzer DNA 100 kit. Illumina HiSeq X was used to sequence the multiplexed libraries. Demultiplexing was performed using bcl2fastq v2.2 (RRID:SCR_015058). Quality of the reads was assessed with FastQC [8] and MultiQC [9] (Data file 2) [10]. The processed reads from both Illumina and Nanopore were used to generate hybrid assembly using Unicycler v0.4.8 [11] and the final assembly quality was assessed with QUAST [12] (Data file 3) [13].

The final complete genome assembly (Data set 1) [14] has a total length of 39,30,130 bp, GC content of 51.0% and genome coverage of 189.69x. A total of 3777 genes were predicted by NCBI Prokaryotic Genome Annotation Pipeline (PGAP) v 4.13 [15] in the genome. These include 3617 protein-coding genes, 78 tRNAs, 18 rRNAs, 4 ncRNAs, and 60 pseudogenes. Genome completeness analysis with BUSCO v3.0.2 [16] using the “gammaproteobacteria_odb9” dataset with 452 benchmarking universal single-copy orthologs (BUSCOs) showed the presence of 100% complete BUSCOs in the hybrid assembly (data file 4) [17]. The genome was found to possess several antibiotic resistance genes, secondary metabolite gene clusters and prophages.

Given the quality control measures applied, we believe the complete genome of M. morganii strain SMM01 represents a high-quality dataset that would enhance the study of the antimicrobial resistance patterns. It may further aid in comparative genomic analyses of this emerging pathogen along with its biosynthetic and metabolic potential.

Table 1 Overview of data files/data sets


The complete genome sequence of M. morganii SMM01 was generated from a hybrid assembly using Illumina and ONT technologies to ensure accuracy and completeness. Further, Unicycler autocorrects read errors and polishes (using Pilon) the assembly to ensure accuracy. Annotation and further downstream specialized analyses were performed using robust and validated bioinformatics tools and webservers. Therefore, the authors are not aware of any limitations in the data.
