Comparative genomics of two Shewanella xiamenensis strains isolated from a pilgrim before and during travels to the Hajj.

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.
