Résumé
Shewanella xiamenensis has been reported in water environment and in patients and can act as the originator of oxacillinase in gram-negative bacteria. In order to assess genome plasticity and its functional properties related diarrhea symptoms in pilgrim, comparisons of draft genome sequences of the two isolates were conducted with other closely related genomes. We isolated S. xiamenensis 111B and 111D strains from a pilgrim before travels to the Hajj and during travels with diarrhea symptom, respectively. Whole-genome sequencing showed that draft genome size of 111B strain was 5,008,191 bp, containing 49 kb of a putative plasmid. The genome size of 111D was 4,964,295 bp containing 225 kb of a putative plasmid that shared the backbone sequences with the hospital wastewater strain T17. Comparatively, two Hajj strains are identical at 97.3% identity and 98.7% coverage. They are closely related to river water strain, AS58 by SNPs analysis. Notably, a novel bla The whole genome sequences of S. xiamenensis strain 111B and 111D, including comparative genomic analysis, highlight here the potential for virulence factors that might be related to the cause of diarrhea in humans and also indicate the possible acquisition of pathogenic bacteria, including antibiotic resistance genes or plasmids during the Hajj.

CONCLUSIONS
The whole genome sequences of S. xiamenensis strain 111B and 111D, including comparative genomic analysis, highlight here the potential for virulence factors that might be related to the cause of diarrhea in humans and also indicate the possible acquisition of pathogenic bacteria, including antibiotic resistance genes or plasmids during the Hajj.
